Cold work die steel compared with cutlery steel in common

Cold work die steel compared with the cutlery steel. There are many things in common. Mould has high hardness and wear resistance, high bending strength and toughness, enough to ensure the stamping process smoothly, the difference between mold shape and complex process. Friction and the area is large. Wear more likely. So difficult to grinding. Therefore requires a higher wear resistance to change mould to work under pressure. And due to the complex shape is easy to produce stress concentration, so the requirement with high toughness; Mold size, complicated shape. So to demand higher hardenability, small deformation and cracking tendency. In a word, cold work die steel hardenability, abrasion resistance and toughness in the requirement for the cutlery steel. 

Performance: the type of high carbon and high chromium ledeburite steel, has a good hardenability and good wear resistance. Because carbon mass fraction of up to 2.30%, in steel and steel becomes hard and brittle, so the impact toughness is bad, almost unable to bear large impact load, brittle crack, and easy to form uneven eutectic carbides. 

USES: used in the manufacture of impact load is small, and require high wear resistance of cold die and punch, shear hard and thin metal cold cutting blade, drill sets, gauge, wire drawing die, stamping die, drawing die and screw thread rolling plate, rolling dies, etc. 

USES: used in the manufacture of impact load is small, and require high wear resistance of cold die and punch, shear hard and thin metal cold cutting blade, drill sets, gauge, wire drawing die, stamping die, drawing die and screw thread rolling plate, rolling dies, etc. 

Products: hot rolled, cold drawn material, forging material, hot-rolled steel, cold drawn steel wire. 

Cold work die steel fatigue fracture resistance: by certain of fracture under cyclic load cycles or in the specified cycles cause sample fracture load values to characterize, small energy available repeated impact rupture work or repeated impact fracture life, a compression fatigue strength or fatigue life, the contact fatigue life of contact fatigue strength or several indexes to reflect.
