nm500 steel chemical composition pressure vessel heavy plate supplier

CortenB vs 45#: Corten B medium-carbon quenched and tempered steel has higher strength, toughness and hardenability than 45# steel. Corten B steel can obtain better comprehensive mechanical properties after quenching and tempering. The cutting performance is still good, but the welding performance is poor, the cold deformation plasticity is low, and the temper brittleness tendency. It is generally used in quenched and tempered state, and can also be used in quenched, tempered or normalized state.

The NM500 steel chemical composition, wear-resistant plate after VD treatment is generally high-quality wear-resistant plate with high added value. In addition to the strict requirements for the composition of wear-resistant plate, the requirements for the anti-fatigue pull-out damage performance of the wear-resistant plate are also very strict. Therefore, the non-metallic inclusions, especially the large non-metallic inclusions and brittle inclusions, must be strictly controlled.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the NM500 steel chemical composition metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between NM500 steel chemical composition strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
