FAQ

• Stainless Steel
• Carbide Steel
• Carbon Steel
• High-speed Steel
• Cobalt Steel

Steel is prepared into various sections like

• Plates and Tubes
• Strip and Profiles
• Rails
• Rods
• Wire and Bar

The main challenges that steel industry is facing now is

• Overcapacity
• High raw material cost
• Price volatility

Impurities percentage is very minimal, and it is added according to the requirements

• Silicon
• Sulphur
• Carbon
• Phosphorous
• Manganese, etc.

There are various methods for doing QC for steel

• Using Microscope: A cross section of highly polished sample is observed under 100-500 magnification diameters. It will reveal the presence of alloy metals in it and help to determine the strength and behaviour of steel under set condition
• Rockwell and Brinell hardness tests: This test is done to check the hardness of steel by impressing into the test specimen.
• Charpy and Izod test: In this test, a metal pendulum of specific weight is allowed to strike the testing sample and after that the energy absorbed by the specimen is measured. This test is done to measure the material behaviour on exposing high rate of loading, bending, tension or torsion
• Salt Bath Immersion techniques: This technique is used to check chemical, electrochemical or metallurgical interaction between the environment and the material
• Magnetic particle inspection: To detect crack, tears, seams and inclusion
• Ultrasonic sound Waves: It is used to detect porosity, internal cracks, shrinkage voids and large non-metallic inclusions
