What is DC53 steel?

DC53, is an improvement over alloy tool steel D-2. It eliminates the disadvantages of insufficient hardness and toughness that are a result of high-temperature tempering found with D-2. DC-53 is noted for causing less tool wear and machining times that are faster than D2 Tool Steel.

How to heat treat DC53?

DC53 can be annealed by uniformly heating the part to 800° C (1,475° F) to 850° C (1,550° F), and holding for 2 hours followed by a slow cooling at no more than 27° C (50° F) degrees per hour to until the it has dropped below 500° C (930° F).

Is DC53 stainless?

DC53 die steel is the preferred die steel for stainless steel stamping dies. Because of the anti-cracking performance of DC53 die steel, it is the better steel in cold work die steel. Of course, DC53, which has poor purity and poor heat treatment, is also easily cracked.

What is SKD11 material?

SKD11 Tool Steel is a high- carbon and high- chromium alloy tool steel. It has good wear resistance and size ability after heat treatment and is suitable for making long-life high-precision cold-work dies. SKD11 Tool Steel of Applications: 1) Making knife-edge mold, scissors, circular saw blades, metal stamping mold.

How good is DC53 steel?

Double the toughness of SKD11 DC53 has relatively well-performing toughness among all cold die steels. Therefore, tools and dies made of DC53 are less faced with the problems such as cracking and chipping, which often seriously affect conventional tools and dies, and enjoy greater durability.

What makes dc53 steel better than D2 steel?

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.

When to use a third temper on dc53 steel?

If size change or distortion of hardened DC53 due machining, grinding, applying surface treatments or wire EDM work is a concern in high precision applications, an optional third temper of 400° C (750° F) can be applied to the initial heat treat process.

What’s the hardness of a mold steel dc53?

Description: DC53 is a general-purpose cold work die and mold steel whose strength and toughness approach those of high-speed steels. Higher hardness (62-63 HRc) than D2 after heat treatment.
