Chemical Analysis

Chemical Analysis finds the percentages of Carbon, Phosphorus, Copper, Manganese, Chromium, and Sulphur with the help of a spectrometer. It reveals the deficiencies and level of impurities in the steel.

Tensile Testing

Stress is applied to a test piece by tensile force, usually to crack it, to determine rigidity, yield quality, and the occasion of failure. The test is performed on mild steel, tor steel, and high tensile steel to determine properties like rate prolongation, Young’s modulus, and high quality. The estimations taken during the test detect the properties of steel when it is under a tensile load. 

Yield Stress Testing

The test determines the level to which steel can handle stress. It tests the approximation of the elasticity limit of the metal. When the load is added to the metal and does not reach the yield point, it will return to its original shape after removing the stress. 

Bend/Re-bend Testing

Here, the TMT bars are bent at the midpoint to 180 degrees to check for cracks and fractures against the bent side. In the re-bend test, the bar is bent at an angle of 135 degrees. After keeping the TMT bar in boiling water at 100 degrees for 30 minutes, allow it to cool down. As soon as it has cooled, twist it again at 157.5 degrees, and look for any cracks or ruptures. It must be visible with normal or corrected vision. If no cracks or fractures appear, the bar is of good quality
