Properties
Stainless martensitic chromium-nickel-steel with high strength and good toughness. High-gloss polishable. Good corrosion resistance (PREN≈19).
The formation of chromium-depleted areas by improper heat treatment increases the risk for intercrystalline corrosion.
Delivery Condition
- quenched and tempered (+QT)
- quench., tempered, stress relieved (+QT +SR)
- annealed (+A) max. 295 HBW
Application Area
Parts for high mechanical loads in corrosive environment.
Standard material for highly stressed shafts, piston rods and valves in all applications.
Typical Applications
- General mechanical engineering and equipment construction
- Chemical and petrochemical industry
- Nonwovens industry, technical textiles
- Surgical instruments
- Water and wastewater treatment
- Oil and gas industry
