And the wear-resistant plates are also used in wheel device, grab equipment, bucket body, edge, lining plate, hopper, funnel, bucket valve, etc. parts.

DC53 mold steel has better machinability and abrasiveness than SKD11. DC53 cold work die steel CCS grade D hull shipbuilding plate is widely used in punching die, cold work forming die, cold drawing die; forming roll, punch; precision stamping die; precision cutting die for wire cutting and punching die for various purposes; difficult to process materials Tools for plastic deformation; cold forging, deep drawing and thread rolling dies; high-speed punching punches, stainless steel punches.

Hydrogen (H) is the most harmful element in general steel such as CCS grade D hull shipbuilding plate. 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.

CCS grade D hull shipbuilding plate product plate specification range:
Thickness 3-150mm
Width 1500-4020mm
Length 4000mm-17000mm
Heat treatment: annealing, or normalizing and tempering
