Thick plate blanking die
Dec 09, 2017

Thick plate blanking die

Stamping die plate punching force to withstand higher than the punching die, die for heavy load blanking, easy to wear, chipping and fracture, it requires the mold material should have high wear resistance and toughness.

Traditional mold steel Traditional heavy duty blanking die steel mainly T8A, Cr12MoV, W18Cr4V,

W6Mo5 Cr4V2 and so on.

Which T8A carbon tool steel, although the hardenability, toughness than the T10A steel has improved, but easy to survive reticular carbide, poor heat-hardening, can only be used for small batch of medium-sized blanking die. T8A tool steel heat treatment process: 790 ~ 820 ℃ water or oil quenching, tempering 160 ~ 180 ℃, hardness 58 ~ 61HRC.

W18Cr4V, W6Mo5Cr4V2 is a high-speed tool steel, with high hardness, compressive strength and wear resistance, but lower toughness, work may have chipping or fracture, and the price is more expensive. It is recommended to use low temperature quenching, rapid quenching and other process measures to improve its toughness. For large workpiece batch blanking die, you can use W18Cr4V, W6Mo5Cr4V2 steel punch, Cr12MoV steel die.

W18Cr4V steel recommended heat treatment: 1220 ~ 1250 ℃ quenching; 550 ~ 570 ℃ tempering 3 times.

W6Mo5Cr4V2 steel's recommended heat treatment process: 1160 ~ 1200 ℃ Quenching: 550 ~ 570 ℃ tempering 3 times.
