The basic information of C53 steel plate:

The DC53 plate is in the SKD11 (Crl2MoV) based on the improvement of the cold die steel, the conventional heat treatment conditions, residual austenite decomposition of almost all of it can be omitted, cryogenic treatment, the hardness of the strong can keep high toughness.

DC53 steel plate heat treatment hardness is higher than SKD11, high temperature (520-530 DEG C) after tempering up to 62-63HRC of high hardness, strength and wear resistance in DC53 over SKD11.

Toughness of DC53 steel plate is 2 times that of SKD11, the toughness of the DC53 die are more prominent in the cold, made of DC53 tools seldom cracks and crack, greatly improving the service life.

Less stress after high-temperature tempering reduced the residual stress line cutting processing of residual, wire cutting processing of crack and deformation after suppression.

DC53 steel plate cutting and grinding of more than SKD11, DC53 cutting and grinding was better than that of SKD11, the use of DC53 can increase the life of tool and die and reduce the machining process.

Manufactured with DC53 tools seldom cracks and crack, greatly improving the service life.

Characteristics and applicable scope of DC53 steel plate:

Application of DC53 steel plate:

Precision stamping die:

Wire cutting machining precision punching die and all kinds of stamping mould

Plastic deformation with the tools of difficult to machining materials.

Mold for cold forging, deep drawing and rolling

Other: high-speed punch, punch stainless steel plate

Factory state: HB255

DC53 steel sheet:

(1) by cutting the sex, be abrasive are better than the SKD11, so that the machining tool life is long, the processing work hours than the province.

(2) the hardening can be higher than SKD11, so it can improve the defects of vacuum heat treatment hardness.

(3) by high temperature tempering can reduce the residual stress and the elimination of residual austenite, can prevent trouble cracking, deformation of the wire cutting.

(4) the surface hardness of surface hardening is higher than SKD11, so it can improve the properties of mould.

(5) as the preheating and post heat temperature are lower than that of SKD11, so the repair welding operation is simple.

DC53 plate and other information:

The appropriate adjustment of quenching temperature, tempering at 200 c hardness and impact toughness of DC53 are higher; in the 400 to 500 DEG C when the tempering hardness, toughness decreased drastically at 600 DEG C during tempering; impact toughness is high, the hardness decreased significantly.

Precision die, mold, cold roll wheel tooling, complex shape of the appropriate use of low temperature tempering process, in order to make the mold work parts to obtain high hardness, high toughness, good wear resistance, high strength, can effectively prolong the service life of the die, to prevent excessive wear, deformation, cracking and other early failure phenomena.

C. by complex mold larger impact load can use low quenching process with high return, the impact toughness is high, to prevent the mold to produce the brittle fracture phenomenon
