High Chrome Casting Manufacturer in China
JC Casting is a professional High Chrome Casting manufacturer, supplier, and foundry in China, specializing in the production of wear-resistant high chromium cast iron castings for mining, cement, power generation, steel plants, aggregate processing, and heavy industrial applications.
With advanced foundry facilities, precision molding technologies, strict quality control systems, and comprehensive material testing capabilities, we provide custom-engineered high chrome castings that deliver exceptional abrasion resistance, impact strength, and extended service life under severe working conditions.
Whether you require OEM wear parts, crusher components, pump parts, mill liners, or customized high chromium cast iron castings, JC Casting can provide reliable manufacturing solutions from prototype to mass production.
What Is High Chrome Casting?
High Chrome Casting refers to wear-resistant castings produced from High Chromium Cast Iron (HCCI), typically containing 12%–30% chromium and 2%–3.6% carbon. The material forms hard chromium carbides (M7C3) within the iron matrix, providing outstanding resistance to abrasion, erosion, and moderate corrosion.
Compared with ordinary cast iron and carbon steel castings, high chrome castings offer:
- Excellent wear resistance
- High hardness (HRC 55–68)
- Good heat resistance
- Improved corrosion resistance
- Long service life in abrasive environments
- Reduced maintenance costs
These properties make high chrome castings ideal for handling abrasive materials such as ore, coal, cement clinker, sand, gravel, and mineral slurries.
