hardox 450 steel wear resistance PVQ steel plate

Carbon steel SA516Gr70 corresponding material is SA516 Gr485 steel. SA516 Gr485 is called according to the min. tensile strength 485MPa. Our company can supply Hardox 450 steel wear resistance, ASME SA516Gr70 carbon steel plate and sheet with thickness ranging from 5mm to 150mm. SA516Gr70 steel plate for pressure vessels and boiler is delivered in hot rolling, controlled rolling, normalizing, while plate thickness greater than 40mm must be normalizing.

In recent years, in line with the development trend of iron and Hardox 450 steel wear resistance steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which Hardox 450 steel wear resistance are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than Hardox 450 steel wear resistance. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel Hardox 450 steel wear resistance is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.

The amount of Vanadium in steel material is generally between 0.04% and 0.12%. The role of Vanadium is to affect the microstructure and properties of steel material. It mainly precipitates in the ferrite at the austenite grain boundary, and can inhibit the recrystallization of austenite and prevent the crystal during rolling. The grains grow, which refines the ferrite grains and improves the strength and toughness of Hardox 450 steel wear resistance etc. steel material.
