|1.4418 Stainless Steel Grades Stocked:|
EN 10088-3 – 1.4418, QT 900
Rounds: 3mm dia. to 520mm dia
- Excellent fatigue resistance
- High tensile strength
- Good weldability
- High toughness, even maintained after welding
- Better corrosion properties than most stainless martensitic steels
This is a high strength, low carbon martensitic stainless steel. In our stock standard condition the steel matrix consists of 80% Martensite, 10% Austenite and 10% Ferrite. This composition allows a low carbon martensitic structure after quenching and tempering.
This grade is designed for applications in slightly corrosive environments, where good fatigue resistance, strength and weldability are required. Specific uses are water turbine parts, propeller shafting, shafting, bolts, shear pins, piston rods and equipment for hydro power stations.
