Stantuf 500 High Strength Low Alloy Steel Plate Manufacturer & Supplier
Stantuf 500 is a quenched & tempered high strength low alloy (HSLA) plate with a minimum yield strength of 500 MPa. Low carbon and micro-alloying give excellent weldability and formability at a far better strength-to-weight ratio than mild steel.
