Cold Work Die Steels DC53 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 DC53 was initially developed with the Wire EDM process in mind. The high temperature double draw 520° C (970° F) or higher was part of the development criteria in determining alloy content, and heat treat requirements for DC53. This high temperature double temper relives a considerable amount of stress in the steel which in turn minimizes movement in the part when Wire EDM cutting hardened DC53.  Click here for more information. WELDING With special care DC53 can be welded. Use any appropriate weld rod such as an H72A rod which is commonly used for high carbon, high chrome die steels similar to D2. The weld rod should be dry to prevent bubble cracks in the weld. Placing the rod in a 350 degrees Celsius (650 degrees Fahrenheit) oven for one hour is generally sufficient.
