Unique Characteristics | Fabrication Characteristics | Heat Treat | Surface Enhancements | Applications Unique Characteristics CHEMICAL COMPOSITION Grade C Si Mn Ni Cr Mo W V DC53 1.0 1.0 0.4 8.0 2.0 0.3 Higher hardness (62-64 HRc) than D2 after heat treatment. Twice the toughness of D2 with superior wear resistance. Substantially higher fatigue strength compared to D2. Smaller primary carbides than D2 protect the die from chipping and cracking. Secondary refining process (DLF) reduces impurities. Machines and grinds up to 40% faster than D2. Less residual stress after wire EDMing. FATIGUE STRENGTH TEMPER RESISTANCE Fabrication Characteristics MACHINING DC53 can typically be machined 20% to 40% faster than D2 while experiencing as much as 50% less tool wear and breakdown. Faster feeds and speeds reduce machining cost and yielding an improved surface finish. WIRE EDM WELDING Heat Treat DC53 HEAT TREAT DC53 is only as good as the heat treatment it receives. The heat treat process can be broken down into two segments, Hardening & Tempering. DC53 is typically air hardened using a vacuum furnace however it can also be processed by using a gas or electric furnace with or without a controlled atmosphere when wrapped in stainless foil or salt bath hardened by immersing the part in high temperature salts. AIR HARDENING SALT BATH HARDENING TEMPERING INSPECTION VACUUM TEMPERING CRYOGENICS FORGING ANNEALING Surface Enhancements SURFACE TREATMENTS DC53 is well suited for supporting a wide variety of surface treatments which include Case Harden Nitride (Nitriding) which is diffused into the substrate tool steel or use the Physical Vapor Deposition (PVD), Chemical Vapor Deposition (CVD) and Thermal Diffusion (TD) otherwise known as Thermal Reactive Diffusion (TRD) which are applied on the surface. Surface treatments are either into the surface of the substrate tool steel which is otherwise known as case hardening or on the surface in the form of a surface coating. These treatments while very hard are also very thin making them nearly impossible to detect using a conventional hardness testing methods. When a combination of diffusion and surface coatings are used, a Vickers Micro Hardness Tester should detect a rise in surface hardness however, it will not reflect the hardness of the actual surface treatment alone.

Dimensions (mm) Cold pressing Ni-based alloy (0.2 mmt) D2 HRc58/59 Tempered at 510°C HRc62/63 Tempered at 520°C 35tx100Wx250L Evaluation 5,000S 25,000S 5 times Considerations Conventional Steel–The worked material is tough and chipping and seizing of the die edge were problematic. DC53–Both high temperature tempering and high hardness are important in preventing seizing and extending the life of the die edges. High hardness, when tempered at high temperature, and homogeneous structure of DC53 were greatly effective in meeting these requirements.
