A2 is an American high toughness wear-resisting tool steel, belonging to the wind hard section steel. The mass fraction of carbon is about 1%, and the hardness can reach 57~62HRC after heat treatment, and the mass fraction of chromium is about 5%. After grinding, the steel surface luster is dark, corrosion resistance is good, ductility is very strong, and the damage resistance of the cutting edge of the mold is good. The steel has good hardenability, uniform carbide distribution, certain impact and good wear resistance. It has good air quenching performance, small size deformation, uniform and fine carbide and good wear resistance after air quenching.
American A2 steel practical characteristics:
(1) be cutting, be abrasive good. The cutting ability and grinding ability are better than SKD11, so the processing tool life is longer and the number of processing hours is less.
(2) In the heat treatment of the advantages of quenching hardening can be higher than SKD11, so can improve the vacuum heat treatment hardness defects.
(3) The advantages of wire cutting by high temperature tempering can reduce residual stress and eliminate residual Wastin iron, can prevent wire cutting cracking, deformation problems.
(4) The advantages of surface hardening treatment after surface hardening treatment surface hardness is higher than SKD11, so it can improve the die performance.
(5) Advantages of repair welding operation because of the lower preheating and post-heating temperature than SKD11, repair welding operation is easier. Features: Universal cold working die steel, high hardness, high toughness.
American A2 steel uses:
● Precision stamping die.
● Precision punching die for wire cutting and stamping die for various purposes.
● Tools for plastic deformation of difficult-to-machine materials.
● Die for cold forging, deep drawing and thread rubbing.
● High speed punching punch, stainless steel plate punch.
● Drawing die, rolling die, embossing die, wear plastic molding die.
