Hot rolled marine grade LR FH40 hull steel plate manufacturer

Q420B material is a low-alloy high-strength structural steel. , Q420 is not high-strength steel, it is still low-carbon steel. Its tensile strength has been improved a bit. The tensile strength of Q235 steel is 235MPa, and the tensile strength of Q420B steel is 420MPa. Q420B low alloy steel has high strength and good fatigue resistance; high toughness and low brittle transition temperature; good Cold forming performance and welding performance; has good corrosion resistance and certain wear resistance.

Marine grade LR FH40 hull steel plate,304 stainless steel plate products have strong corrosion resistance. For ordinary alkali solution and organic acid, inorganic acid has good corrosion resistance. This material is a high alloy steel, which can resist corrosion in air or chemical corrosive medium.
