hardess of nm500 steel plate price may fluctuate in a narrow range recently

ASTMA335 steel pipe of grades P23,P91, P92, P122, and P911 shall be reheated and furnished in the full-annealed, isothermal annealed,or normalized and tempered condition. If furnished in the normalized and tempered condition, the minimum tempering temperature for Grades P5, P5b, P9, P21, hardess of NM500 steel plate product and P22 shall be1250°F [675°C], the minimum tempering temperature for Grades P1, P2, P11, P12, and P 15 shall be 1200°F [650°C].

hardess of NM500 steel plate, low alloy high strength steel can meet the requirements of various structures (such as large bridges, pressure vessels, ships, etc.) in engineering. At the same time, it is required to reduce the weight of the structure, improve the reliability and save materials and resources. Low alloy high strength steel is mainly used to manufacture various engineering structures with high strength requirements, such as bridges, ships, vehicles, high pressure vessels, oil and gas pipelines, large steel structures, etc. Because low alloy high strength steel can obtain high strength without complicated treatment process or even heat treatment, the quality of engineering structure is greatly reduced. Therefore, low alloy high strength steel is commonly used to replace the general carbon structural steel.

Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled hardess of NM500 steel plate products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the hardess of NM500 steel plate rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.
