Mechanical Testing of Steel

At Raipur Metallurgical Lab (RML), we offer a comprehensive range of Mechanical Testing Services to assess the properties of materials like steel, ferrous, and non-ferrous metals. Our laboratory is equipped with the latest and most sophisticated equipment to perform mechanical tests according to national and international standards..

Mechanical Testing of Steel Used For

Mechanical testing of steel is the process of checking how steel performs under different conditions. It helps determine the strength, flexibility, and durability of steel to make sure it can handle the forces and pressures it will face in construction. These tests help engineers and builders ensure the steel used in buildings, bridges, or other projects will perform well and last a long time.

At Raipur Metallurgical Lab, we perform all necessary mechanical tests on steel to make sure it meets the required standards for construction needs.

Tensile Testing

Tensile testing is a crucial process that helps determine the strength and flexibility of materials under tension. It is used to measure how much stress a material can withstand before breaking or deforming.

At Raipur Metallurgical Lab (RML), we are equipped with two FIE make electronic Universal Tensile Machines, with capacities of 60 kN and 100 kN, which are used to test materials under both tension and compression.

Through tensile testing, we can determine key mechanical properties of materials, including:

Ultimate Tensile Strength (UTS)

Yield Stress (YS)

Proof Stress

% Elongation

% Reduction in Area

We conduct these tests on a variety of materials such as plates, pipes, TMT bars, and both ferrous and non-ferrous materials.

Bend & Rebend Testing

Bend and rebend testing are important processes used to check the ductility and flexibility of materials, especially metals like TMT bars. These tests help determine how much a material can bend without breaking or developing cracks, which is essential for construction materials that need to withstand forces and pressure.

At Raipur Metallurgical Lab (RML), we are equipped with various mandrel sizes to perform bend and rebend tests according to the requirements of different national and international standards, such as IS, ASME, AWS, ASTM, and others.

We use these tests to ensure that the materials used in your projects have the necessary strength, flexibility, and durability to meet industry standards.

Hardness Test

Hardness testing is an important process used to measure how resistant a material is to indentation, scratching, or wear. It helps determine the strength and durability of materials like steel, alloys, and castings.

At Raipur Metallurgical Lab (RML), we use a Saroj Make Brinell Hardness Machine to determine the hardness value of various materials, including:

Forging Materials

Castings

Plates

Rounds

Alloy Steels

This machine applies a specific load to the material and measures the size of the indentation left on the surface. The hardness value helps engineers and manufacturers understand how well the material will perform under pressure or wear and tear.

By conducting hardness tests, we ensure that the materials used in your projects meet the necessary strength and durability standards.

Impact Testing

Impact testing is used to evaluate the toughness and notch sensitivity of materials, especially metals. It measures how well a material can absorb energy before it fractures, helping to determine its resistance to sudden impacts or shocks. Impact testing is particularly important for metals like carbon steels, which can experience a "ductile to brittle transition" at low temperatures. This behavior is tested by exposing materials to sub-zero temperatures to evaluate how they respond to impacts in cold conditions.

Charpy Impact Testing

The Charpy Impact Test, also known as the Charpy V-notch Test, is a standardized test that determines the amount of energy a material absorbs during fracture. In this test, a pendulum hammer strikes a notched specimen, and the energy absorbed by the specimen during the fracture is measured. There are two types of notches used in this test:

V-notch

U-notch

This test helps assess the material's toughness and its ability to withstand impacts without breaking.

Izod Impact Test

The Izod Impact Test is another method to measure the impact resistance of materials. In this test, the specimen is clamped vertically with the notch facing the striker. A pendulum hammer strikes the specimen, and the amount of energy absorbed is measured. The key difference between the Charpy and Izod tests is that in the Izod test, the notch faces the striker, whereas, in the Charpy test, the notch is positioned away from the striker.

Both tests are essential for understanding how materials will perform under sudden impacts and ensuring their suitability for engineering applications where toughness is crucial.

Microstructure Analysis

Microstructure analysis is an essential process for examining the internal structure of metals. It provides valuable insights into the material’s properties, helping to determine its performance and suitability for various applications. At Raipur Metallurgical Lab (RML), we use advanced technology to conduct detailed microstructure analysis of metals like steel, iron, and aluminum.

We are equipped with a Metallurgical Microscope named MAIS (Metallurgical Image Analysis System), which is an advanced system for metallographic studies. This system is based on technology transferred from the Bhabha Atomic Research Centre (BARC) and complies with ASTM Standards. The system uses fully automatic software to analyze the microstructure of materials, ensuring precise and reliable results.

Key Characteristics We Analyze:

Grain Size Analysis

Nodularity

Inclusion

Decarburization

Phase/Segmentation

Flake Analysis

Porosity Analysis

With this advanced system, we can provide you with detailed insights into the properties of your materials, helping ensure their quality and performance in various applications.
