25CD4S - 1.7214 - Available from stock
The 25CD4S is analloy steel, weak in carbon and enriched mainly with chromium and molybdenum.
Technical overview of this steel:
- Europe: 25CD4S | 25CrMo4 | 1.7214
- Europe: EN 2205 | EN 2206 | EN 2209 | EN 2542 | EN 2543
- Good general mechanical properties, including tensile strength and ductility.
- Creep strength: efficient at high temperatures, which is important for long-term under-load applications.
- Excellent weldability due to its low carbon content, meaning welded structures can be manufactured without any need for preheating in many cases.
- Can undergo quenching and tempering to enhance its mechanical properties.
- 25CD4S is a specific name that emphasises the steel’s chemical make-up and properties, especially for welding, and mechanical strength.
