Benefits of DC53

Benefits of DC53

Welding
Lower minimum pre- and post-heating temperature than D2 reduces the incidence of weld cracking and simplifies welding. Low hardness decline in heat affected zone minimizes deterioration in die performance.

Weld Rod - any appropriate weld rod used for high carbon, high chrome die steels such as D-2.

Machining/Grinding
Machines and grinds better and faster than D2 for longer tool life and reduced tool manufacturing time.

EDM
Residual stress caused by quenching is minimal in DC53. Therefore, problems such as cracking and distortion are prevented during and after wire electro-discharge machining.

Sub-surface hardness decline of DC53 just below wire electro-discharge machining is much less than D2; thus making DC53 dies more durable.

Stability
High-temperature tempering (520C) allows maintenance of die accuracy without the troublesome application of subzero treatment, reducing costs and increasing productivity.

Surface Enhancements
Surface hardening treatments such as CVD, PVD, TD, and nitriding require the use of high temperatures. DC53s higher inner hardness than D2 after such treatments, preventing the hardened layer from peeling off and making surface hardening treatments more effective.

Wear
Superior wear-resistance coupled with high toughness make DC53 suitable for use in
wear-resistant parts subject to impact and bending stress.

Strength
Dies made of DC53 and heat-treated using standard method possesses up to 25% higher bending strength than D2. Secondary refining decreases nonmetallic inclusions and carbide size for a substantially increased fatigue strength that of D2.

Toughness
Superior impact value minimizes fracture and chipping problems thus ensuring more durable dies.
