High Hardness Mold Steel Supplier
High Hardness Mold Steel Supplier
High Hardness Mold Steel Supplier | Precision Tool Steel for Extreme Conditions
is commonly used in the manufacturing of molds and dies for industrial applications. It’s known for its ability to withstand high pressures and temperatures, making it ideal for processes like injection molding, die casting, and extrusion molding. The steel is typically treated to achieve a high level of hardness, which enhances its durability and performance in shaping materials like plastics, metals, and rubber.
Some common types of high hardness mold steels include:
H13 Tool Steel – Known for its excellent toughness and resistance to thermal fatigue, it's often used for hot working tools and molds.
P20 Steel – A versatile mold steel known for its ease of machining and good hardness properties.
D2 Steel – A high-carbon, high-chromium tool steel that is hardened to a very high level, offering great wear resistance.
S7 Steel – A shock-resistant steel with high toughness and hardness, suitable for heavy-duty applications.
Why Choose Our High Hardness Mold Steel?
Unmatched Durability
Hardness range: 50-65 HRC (Customizable via vacuum heat treatment)
Wear resistance: 3-5x lifespan vs. conventional steel in aluminum die casting molds
Thermal stability: Maintains hardness up to 600°C (H13 steel for hot forging dies)
Material Innovation
Micro-alloying technology: Vanadium/Niobium additives refine grain structure (e.g., DC53 steel with 0.9% V)
Surface hardening options: Nitriding/TiN coating for critical components like injection mold cores
Certified Quality
ISO 9001 & IATF 16940 certified production
Full traceability: Mill test reports with chemical composition & impact toughness data
