HSLA SA283 Gr D carbon steel plate sheet supplier

Q690D steel material is a low-alloy ultra-high strength steel grade. Standard: GB/T 3077. The hardenability of steel is high, and the critical hardenable diameter in oil is 60mm (96% martensite). After quenching and tempering, steel can obtain high strength, and has certain toughness, and can be processed into shape. But cold deformation plasticity and weldability are low.
