A573 Gr 70 chemical composition Delivery State

DC53 mold steel has better machinability and abrasiveness than SKD11. DC53 cold work die steel A573 Gr 70 chemical composition 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.

The advantage of hot-rolled stainless steel plate is that it can eliminate the damage caused by A573 Gr 70 chemical composition metal structure in the process of ingot casting to a certain extent, eliminate some tiny defects in the structure, refine the grains of stainless steel material, promote the structure of steel closer, and improve the performance of the material as a whole. This kind of lifting is mainly manifested in the rolling direction, which can make the A573 Gr 70 chemical composition steel no longer isotropic to some extent, and some defects such as bubbles, cracks and looseness formed during pouring can be eliminated under high temperature or high pressure.

Firmly establish the "people-oriented, safe development" concept, strictly follow the safety production policy of "safety first, prevention first, comprehensive management", strengthen and improve the management and supervision of safety production in an all-round way, and strive to improve the controllability of safety management And effectiveness, cultivate safety culture, improve long-term safety production mechanism, and build a harmonious BEBON.
