Characteristics of SKD11 Cold Work Mold Steel
High Hardness and Wear Resistance
Heat-treated hardness: Up to 58-62 HRC (can be elevated to 62-63 HRC through special treatment in specific applications), meeting the demands of high-load cold work molds.
Source of wear resistance: High carbon (1.4%-1.6%) and chromium (11%-14%) contents form abundant carbides, significantly enhancing wear resistance and extending mold service life.
Typical applications: High-wear scenarios such as punching dies for stainless steel plates, deep-drawing dies for mobile phone metal casings, and hardwood carving tools.
Excellent Toughness
Impact resistance: Impact toughness ≥4.8 J/cm², enabling it to withstand impact loads in complex-shaped molds and reducing the risk of chipping or cracking.
Crack resistance: Fine and uniform carbide particles result in minimal loss of toughness after quenching, making it suitable for molds prone to impact (e.g., shearing blades, punches).
Corrosion Resistance
Role of chromium: The high chromium content (11%-14%) provides a degree of corrosion resistance. While not as robust as stainless steel, it maintains stable performance in humid or mildly corrosive environments.
