ABS DH40 rolled steel plates composition characteristics

Katalor Steel can roll various specifications of ABS DH40 rolled steel plates and ABS Grade DH40 shipbuilding steel sections according to user requirements. It can also cut steel plates and special-shaped parts according to user requirements, and deliver finished or semi-finished products.

ABS DH40 rolled steel plates composition characteristics:
Low carbon due to high requirements for toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%.
ABS DH40 rolled steel plates add manganese-based alloy elements.
Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of the steel. In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, and improve toughness and process performance.
