- Good - Best resistance within the group of materials classed as martensitic stainless steels, but also susceptible to intergranular corrosion
Machinability
Poor
Weldability
Good
Other properties
- Nickel-free martensitic ferromagnetic structure with high tenacity - The steel is usually tempered (Rm = 1400 N/mm²/Rp0.2 = 1200 N/mm²) - Can be mechanically polished to a mirror finish - Suitability for electropolishing: good - For use in the temperature range -40° - 400°C
Main uses
Machine and structural parts that are subject to high levels of mechanical stress in the food, petrochemistry, seafaring, automotive, aviation or chemical industries: - Pump parts - Helical and turbine blades - Compressor wheels - Piston rods - Shafts - Valve cones
