Top Choice for Overall Cost-Performance: DC53
Key Advantages: Offers twice the toughness of SKD11 at only a slightly higher price. Hardness reaches 62–63 HRC after high-temperature tempering (520–530°C). It outperforms SKD11 in wear resistance, crack resistance, and machinability (cutting/grinding), significantly reducing the risk of chipping or cracking failures and extending service life.
Typical Applications: Precision stamping dies, cold forging dies, deep-drawing dies, stainless steel sheet punches, and most standard cold-work die applications.
Versatile, High-Value Choice: A2 (Equivalent to GB 5CrMo1V / JIS SKD12)
Key Advantages:Known as a general-purpose cold-work die steel, it offers balanced overall properties and excellent machinability. It ensures high processing efficiency, minimal heat-treatment distortion, and low manufacturing costs, with a die life reaching 110,000–120,000 cycles.
Typical Applications: Hardware stamping dies, drawing dies, thread-rolling dies, cutting blades, and other standard cold-work die applications operating at room temperature.
Entry-Level, High-Value Choice: Cr12MoV
Key Advantages:Costs only 15–20% more than the traditional Cr12 grade but offers double the toughness and double the die life. When calculated based on the cost per die unit, it is far more economical than Cr12. It is widely available on the market and easy to procure.
Typical Applications: Cost-sensitive applications involving standard cold stamping dies and silicon steel sheet blanking dies, provided there are no heavy impact loads.
