P355NH pressure vessel steel sheet material size list and range

Hydrogen (H) is the most harmful element in general steel such as P355NH pressure vessel steel sheet. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.

We have efficient and quick logistic team service. We promise that after the customer places the order, the spot products will be shipped, processed, and cut on the same day. The steel P355NH pressure vessel steel sheet products will be shipped in 2-5 days according to the characteristics of the product. The company has always been adhering to the service concept of "integrity, pragmatism, enthusiasm" and dedicated to providing our customers with high-quality steel products and after-sales service.

P355NH pressure vessel steel sheet product plate production process:Raw materials (scrap steel, pig iron and molten iron) → electric furnace (100 tons electric arc furnace smelting) → converter → LF furnace molten steel refining treatment → VD or VOD furnace molten steel vacuum treatment → die casting (various key die casting lines) or continuous casting (large Slab caster) (50 tons of slab electroslag furnace for remelting a steel ingot) → heating (continuous furnace and soaking furnace) → steel plate rolling (4100 and 4200mm rolling mills) → steel plate heat treatment (normalizing and tempering) Quality) →Steel plate cutting inspection→Inspection
