Introduction Cold Working Tool Steel(1.2746)
The cold working tool steel focuses on the hardness and wear resistance. High carbon content, alloy elements to increase hardenability and improve wear resistance. Cold work tool steel includes moulds for blanking, blanking, punching, trimming, punching, scissors, cold heading and cold extruding, bending and drawing dies.
Compared to cold work tool steel and tool steel. There are many things in common. It is required that the die has high hardness and wear resistance, high bending strength and enough toughness to ensure the smooth progress of stamping process. The difference lies in the shape and the process complexity of the die, and the large area of friction and the possibility of wear. Therefore, it is difficult to repair. So the wear resistance of the die working better withstand the punch pressure. Also, due to the complex shape is easy to produce stress concentration, so the requirements of high toughness; die size and complicated shape. The deformation and cracking tendency therefore require a higher hardenability, smaller. In a word, to be higher than the cutting of steel cold permeability, wear resistance and toughness of tool steel in quenching requirements. But in terms of red hardness, low requirements or basically not required (because it is cold forming, so the corresponding) formed some suitable cold working die steel, for example and the development of high wear-resistant steel, micro deformation and high toughness cold working die steel for cold working die.
Characteristic (1.2746)
Vacuum degassed refining steel with pure inner quality.
Good machinability (20% more cutting than SKD1).
Good hardenability, air quenching and hardening (not easy to crack).
Excellent wear resistance (used as a blanking die for stainless steel and high hardness material) Good toughness.
