Is carbon steel 20#? Carbon steel means that alloy elements are not specially added into the steel, which is divided into ordinary carbon structural steel and high-quality carbon structural steel. The grades of ordinary carbon structural steel are Q195, Q215, Q235 and Q275. The grades of high quality carbon structural steels are: 10#, 20#, 45#, 15Mn, 20Mn, 25Mn, 30Mn, 35Mn, 40Mn, 45Mn, 65Mn, etc. It can be seen that hot rolled RA 40 hull steel plate, 20# steel is carbon steel, but carbon steel means more than 20# steel.
The tensile strength of seamless steel pipe is more than 8-10 times of that of ordinary steel, and its elastic modulus is better than that of steel, with excellent creep resistance, corrosion resistance and seismic resistance; the mechanical performance of seamless steel pipe is excellent, easy to machine, etc.; the seamless steel pipe hot rolled RA 40 hull steel plate is highly elastic, reused in mechanical equipment, memoryless, deformation free, and antistatic.
keyword} 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
