Alloy Structural Steel

 

The alloy structural steel is widely used in automobile manufacturing, railways, ships, aircraft, missiles, weapons,  bridges, pressure vessels, heavy machine tool manufacturing etc.,

​

The main futures are 

• Varying yield strength, tensile strength, resistance to tempering.

• Excellent physical or mechanical properties after specific heat treatment

• Widely used in almost all critical industries.
