1.2888 – RM10Co steel is a high-alloy special steel with extremely high tempering resistance. RM10Co is suitable for particular requirements in respect of hightemperature wear resistance and resistance against molten metals. Both 1.2888 and 1.2885 materials have Co content and they are within our capacity.

Chemical composition%of the ladle analysis of grade1.2888
| Element Name | Content Range | Role in X20CoCrWMo10 - 9 Steel |
|---|---|---|
| Carbon (C) | Approximately 0.17 - 0.23% | Determines the strength and hardness of the steel; forms carbides to enhance wear resistance; the content is strictly controlled to avoid excessive brittleness caused by a too high carbon level. |
| Cobalt (Co) | Approximately 9.5 - 10.5% | Improves high-temperature strength and stability; enhances red hardness, enabling the material to maintain its hardness and strength at high temperatures, making it suitable for high-temperature applications such as gas turbines and aerospace components. |
| Chromium (Cr) | Approximately 9 - 10% | Provides corrosion resistance by forming a passive oxide layer; contributes to improving hardenability, allowing the steel to maintain the required mechanical properties after heat treatment. |
| Tungsten (W) | Approximately 5 - 6% | Improves strength and wear resistance by forming hard carbides; has a positive impact on high-temperature strength, enabling it to perform well under high-load and high-temperature conditions. |
| Molybdenum (Mo) | Approximately 1.8 - 2.2% | Improves hardenability; contributes to improving high-temperature strength and creep resistance; can dissolve in the matrix or form carbides to enhance the mechanical properties in high-temperature and high-stress applications. |
| Vanadium (V) | Approximately 0.1 - 0.5% | Forms hard and stable vanadium carbides, significantly enhancing wear resistance and strength; has a beneficial effect on the grain refinement of the steel, thereby improving its toughness and fatigue resistance. |
| Silicon (Si) | Approximately 0.15 - 0.35% | Helps with deoxidation during the smelting process; has a slight impact on strength and hardness. |
| Manganese (Mn) | Approximately 0.4 - 0.6% | Helps with deoxidation; improves hardenability and strength to a certain extent. |
| Phosphorus (P) | ≤ 0.03% | Maintained at a low level because an excessive amount will lead to brittleness and reduce the quality of the steel. |
| Sulfur (S) | ≤ 0.035% | Maintained at a low level because an excessive amount will lead to brittleness and reduce the quality of the steel. |
