Use Of Cold-made Die Steel
Jul 26, 2018

Cold die steel used to make die (blanking die, die, bending mold, etc.), heading die, cold extrusion and drawing film, rolling wire mold, rubbing wire board. They have to make the metal at room temperature in the mold to create plastic deformation, and therefore under great pressure, friction or impact. Cold as the normal failure of the mold is excessive wear, sometimes will be brittle broken, cutting edge and early scrap. Therefore, cold die steel and cutting tool steel in the use of the requirements are very similar, mainly require high hardness, high wear resistance and sufficient strength and toughness, but also have a higher hardenability and lower quenching deformation tendency.
