Core Key Advantages
- Outstanding Work-Hardening Performance: Original hardness is around 200HBW; under continuous impact and friction, surface hardness quickly rises above 500HBW, while the internal matrix remains high toughness to avoid fracture.
- Superb Impact & Abrasion Resistance: Single-phase austenite structure prevents brittle cracking under heavy shock, ideal for severe wear & impact working conditions.
- Non-Magnetic Property: Suitable for equipment operating in magnetic interference environments.
- Custom Alloy Optimization: We add Cr, Mo, Ni, W elements to upgrade anti-wear, anti-crack and high-temperature performance based on client working conditions.

Our Heat Treatment Technology
High manganese steel castings must be heat treated to improve their performance before use.
We do precise and smart temp control heat treatment-water quenching for all of our high Mn steel castings. Its main procedure is:
- Heat to 1050–1100℃
- Hold temperature 2-4 hours
- Rapid water quenching to get single-phase supersaturated austenite structure, which is the base of high work hardening and toughness.
Common Cracking Causes & Preventive Solutions
Below is the list of reasons may cause cracks on high manganese steel castings, according to our long-term manufacturing experience.
|
Cause Category |
Causes |
Prevention Measures |
|
Structural Design |
Large wall thickness change |
Control thickness difference less than 3mm, add big enough fillets (internal R≥5mm, external R≥3mm) |
|
Casting |
Excessively high or low casting temperature |
Precisely control casting temperature with correct range |
|
Wrong pouring speed |
Adjust pouring speed |
|
|
Unexperienced design of casting gate and risers |
Optimize mold design, using side risers instead of top riser |
|
|
Wrong operation of gate and riser cutting |
Using easy cutting riser; using saw cutting instead of flame cutting |
|
|
Heat Treatment |
Fast temperature change, large temperature difference between castings and furnace |
Preheating 1-1.5 hour below 650℃, then rise the temperature. Slower heating: ≤30-40℃/h when temperature ≤650℃; ≤50-60℃/h when temperature ＞650℃ Rapidly immerse castings into water |
