What is Metal Testing?

Metal Testing services are a set of procedures that are used to evaluate the physical and mechanical properties of metal materials. These services typically include tests such as tensile testing, hardness testing, and impact testing to determine the strength, ductility, and toughness of a metal. Other tests such as chemical analysis, corrosion testing, and microstructure analysis can also be performed to determine the composition and quality of the metal. These tests are performed on various types of metals like Aluminium, Copper, Iron, Steel, Zinc, Nickel, etc.


The results of these tests can be used in a number of ways, such as:
Quality Control: To ensure that the metal materials used in a project meet the necessary specifications and codes, and are suitable for their intended use.
Compliance: To ensure that metal materials and structures comply with industry standards and regulations, and meet safety and performance requirements.
Research and Development: To develop new metal materials or improve existing ones through testing and characterization.
Failure Analysis: To determine the cause of failure in a metal component or structure, and identify ways to prevent similar failures in the future.
Material Selection: To compare different metal materials and determine which one is the most suitable for a particular application.

Overall, Metal Testing in Chhattisgarh plays a vital role in ensuring the quality, safety and reliability of metal-based products, structures and components.

MECHANICAL TESTING PARAMETER
Tensile Test :- For tensile tests, we have a computerised universal testing machine (UTM) with a 1000 KN capacity. The resistance of a material to a static or gradually applied force is measured by a tensile test. In the testing apparatus, a machined specimen is put, and load is applied. Elongation is measured using a strain gauge or extensometer. Tensile strength is defined as the stress produced at the maximum applied force. The yield strength is the stress under which a certain amount of plastic defines how far the specimen can be stretched without breaking. Using a tensile yet, one can learn about a material's strength, stiffness, and ductility.
Bend Test & Re-Bend Test :- The process of bend testing is used to assess the relative ductility of metal that is to be manufactured (often sheets, plates, or wire), as well as the soundness and toughness of metal. Typically, the specimen is bent over a mandrel with a predetermined diameter.
Hardness Testing :- Hardness testing evaluates a material's resistance to penetration and quantifies the indentation's permanent depth. Metal Testing in Chhattisgarh is incredibly helpful in the material selection process since it produces a hardness value, which shows how easily a material can be machined and how well it will wear. Simply put, the harder the material is, while employing a fixed force and a specific indenter.
Impact Test :- Engineering materials can be assessed for their toughness and notch sensitivity using the impact test. Metals' toughness is typically tested using this method. The impact of a heavy pendulum or hammer falling at a fixed distance at a predetermined speed causes the test specimen with notches to break. Metal Testing in Chhattisgarh test gauges the amount of energy the fragmented specimen has absorbed.
I. CHARPY IMPACT TEST :- A "V" or "U" Notch is used to mill a test specimen to a 10 mm X 10 mm (full size) cross section. Where the material thickness is constrained, sub-size specimens are used. At cryogenic temperatures, specimens can be tested.
II. IZOD IMPACT TEST :- The test sample is made of machined steel and has a square, round section with one, two, or three notches. It is clamped vertically on the anvil with the notch facing the hammer.

One of the well-known companies that provides Spectro chemical testing for different types of metals & alloys of engineering materials is National Building Material Lab as well as we are top provider of Metal Testing in Chhattisgarh. This facilitates research into the test materials' varied chemical characteristics. We have a German-made SPECTROMAXx system installed, which can examine both ferrous and non-ferrous metal.
It has incredibly simple operation. All operational parameters are independently monitored by the SPECTROMAXx arc/spark OES metal analyzer. Based on the provided sample attributes, it dynamically calculates the necessary measurement time and even indicates when the spark stand needs to be cleaned depending on the type of samples being investigated.
Its spark OES technology is dependable and extremely potent, making it the most extensively used method in the field of solid-state analysis of metals and alloys. Its appeal is a result of its quick speed. It is great to use since it does not require sample dissolution and because it produces a huge amount of sample analysis output, 400 to 500 samples can be analysed in a single day. These advanced tools provide multi-element analysis and are quite sensitive. In comparison to the conventional wet analytical approach, it is also time and money efficient.

Metallography testing facilities are just one of the exact testing services that National Building Material Lab provides. Metallography is the discipline of science that uses microscopic methods to explore the structure and behaviour of metals and alloys. The primary goal of doing metallographic tests is to look at the microstructure of any sample of a metal or alloy. By using a light optical or scanning electron microscope, the three-dimensional arrangement of atomic elements ranging from 1 pm to 1 mm is investigated.
Phase transition, volume fraction, grain size, depth banding, non-metallic inclusion in steel, porosity cross contamination, and a number of other intriguing characteristics are studied within the microstructure category. The microstructure denotes the mechanical characteristics, such as ductility, influence, toughness, and corrosion resistance. Because understanding and controlling behaviour of metals and alloys requires a thorough understanding of their microstructure, NBML provides Metal Testing in Chhattisgarh that support quality control, failure analysis, and research and development.
The metallurgists at NBML are highly skilled in the metallographic preparation and examination needed to assess the properties of metals. They have a high level of expertise in evaluating the heat treatment state, microstructure, and forming procedure of a certain material. The team conducts macro- and micro-examinations, including weld examination, case depth and decarburization measurement, micro-hardness testing, and coating/plating evaluation.

Micro-Examination : This is done on samples that have been either mounted on a resin mould or cut to size. These samples are polished to a smooth finish, often using a one-micron diamond paste, and are normally etched in the proper chemical solution before being examined under the metallurgical microscope. The most frequent use of micro-examination is to evaluate the material's structure, while it can be used for a variety of other applications as well. In addition to micro-examinations, several standard procedures, such as phase counts or particle size assessments, are carried out.
Macro-Examinations : A specimen is etched during macro-etching, and macro-structural analysis is performed at low magnifications. It is a method that is widely used to assess steel goods like billets, bars, blooms, and forgings. For both carbon and low alloy steels, there are many methods for evaluating a steel specimen using a graded series of images that demonstrate the occurrence of specific circumstances. Depending on the type of investigation, a variety of different etching reagents may be utilised. Because of differences in chemical composition, manufacturing processes, heat treatment, and many other factors, steels respond differently to etching reagents.
Polished and etched cross-sections of welded material are also subjected to macro-examinations. The weld run sequence, which is essential for weld procedure qualifications exams, is one of the elements that can be determined throughout the examination. In addition, the sample's flaws are examined for conformance with applicable criteria. Slag, porosity, a lack of weld penetration, a lack of sidewall fusion, and an unsatisfactory weld profile are some of the characteristics seen in this kind of study. Such flaws can be detected procedurally using magnifications up to 20X or a conventional visual check. A photomicrograph, which is a common practice, is a photograph of the part that serves as a permanent record.
Weld Examination : There are various ways to evaluate welds using metallographic and one of them is metal testing and we provide Metal Testing in Chhattisgarh. Weld deposits can be visually inspected for significant flaws such porosity or a lack of fusion defects in its most basic form. On a smaller scale, the study might take the shape of a phase balance analysis of the weld cap or weld root, or it might even involve looking for non-metallic or third phase precipitates. Determine the causes of subpar mechanical test results by looking at weld development patterns.
Case Depth : Case Hardening is the process of hardening ferrous materials so that the surface layer, also known as the case, is significantly harder than the other materials (known as the core). Carburizing, nitriding, carbonitriding, cyaniding, induction, and flame hardening are used to manage this process. These procedures have an impact on the mechanical qualities and chemical composition. The suitable methodology is chosen depending on specific requirements and can be chemical, mechanical, or optical for determining case depth.
Decarburization Measurement : Decarburization measurement is a technique used to identify changes brought on by carburization in the microstructure, hardness, or carbon content of steel sections. A consistent microstructure, hardness, or carbon content of the specimen interior are observed to estimate the depth. This technique finds carbon content surface losses brought on by heating at high temperatures.
Evaluation of Coating or Plating : The main purpose of coating or plating is to protect the substrate. The performance of the coating or plating is significantly influenced by thickness. The specimen has a section that has been cut off, mounted transversely, and processed using methods that are acceptable or appropriate. An optical microscope is used to gauge the cross section's thickness. The evaluation of plating can be aided by thickness measurements, surface analyses, and cross-sectional metallographic studies of substrates with plating.
Grain Size Determination : In order to establish a scale for grain size, ASTM E112 shows charts with outline grain structures for various dimensions. These universally accepted standards range from ASTM NO. 00 (very coarse) to 10 (very fine). A material's grain size is important as it affects its mechanical properties. In most materials, a refined grain structure gives enhanced toughness, and alloying elements are deliberately added during the steel-making process to assist with grain refinement. Grain size is determined from a polished and etched sample, using optical microscopy at a magnification of 100X or 500X.
