40B steel plate is alloy structural steel plate formed by adding boron to the carbon structural steel with a carbon content of 0.40%. en 10149-2 s420mc equivalent, 40B steel plate has high hardness, toughness and hardenability, and has good comprehensive mechanical properties after quenching and tempering, which can be used instead of 40Cr steel. 40B steel plate chemical elements: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.60-0.90, B: 0.0005-0.0035. 40B steel plate is used to manufacture parts with larger section and higher performance requirements.

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
