Product Description

Cold work  steel DC53 Forged Steel Bar GB Crmo2VSI Steel Bar Manufacture Cheap price

DC53 modified form D2/1.2379/SKD11 etc, with high wear-resisting cold working, die steel, HSSD DC53 steel has the properties of high strength and high wear resistance, replace a new generation imported common cold working die steel with high Abdur ability high wear-resisting.

DC53 is a vacuum melting chrome-nickel-molybdenum alloy steel, quenched and tempered before delivery, has the following advantages: no quenching and heat treatment deformation risk; no heat treatment costs; shorten the mold production cycle; reduce the mold required Cost (for example, no need for out-of-plane deformation); molds are easy to modify; nitriding and surface hardening treatments can be applied to enhance the surface hardness and wear resistance of the mold.

Specifications
DC53, Cr8Mo2SiV Good abrasive resistance, tenacity.Direct sales from the factory & Best after-service.Delivery hardness:≤255HB

Heat Treatment condition
Quenching temperature: 1000-1040 degrees Celsius.Cooling Medium: oil-cooling or air-cooling.Tempering temperature: 180-200 degrees Celsius, by two times; Tempering Hardness: 63.HRC.1060-1080 degree Celsius

Application
Suitable to make the punch dies or drawing dies which are complicated in shape and high in precision; to make the cold-work dies formed by linear cutting; high-speed punch head and cold forging die;

5.Feature: 

1.Easy to be machined and ground. The machinability and grind ability are better than SKD11, so the tool life is longer and the machining time is less.

2. The advantages of heat treatment are that the hardening capacity of quenching is higher than that of SKD11, so the defect of insufficient hardness in vacuum heat treatment can be improved.

3. Advantages in wire cutting processing: high-temperature tempering can reduce residual stress and eliminate residual austenite, preventing cracks and deformation caused by wire cutting.

4. Advantages of surface hardening treatment: the surface hardness after surface hardening treatment is higher than that of SKD11, so the mold performance can be improved.

5. Advantages in repairing and welding operations: since the preheating and post-heating temperatures are lower than those of SKD11, it is easier to repair and weld. Features: universal cold die steel, high hardness, high toughness DC53 die steel.

6.Application:
Used for various large-sized or medium-sized precision plastic mold and alloy parts. 
Ideally suited for the production of plastic molds; 
Die holders, zinc die casting dies, backers, bolsters and injection molds; 
Shafts rail and wear strips; 



7. Stock:
