Open Die Forging ss420 Steel Turbine Blade Steel Steam Blade

Forged steel blade with1.4021 420 SUS420JI

This grade(1.4021, sus420JI, 420) is designed to achieve a good balance of corrosion resistant and mechanical properties. The chromium and molybdenum provides corrosion resistance. The low carbon and increased nickel content provides a high strength martensitic structure but with good toughness. There are also significant amounts of austenite and ferrite in the steel. This structure also gives a much improved weldability compared to normal and higher carbon martensitic grades. It is proving to be a replacement for grade 431 (1.4057) in some applications.
Applications which illustrate these features include:
Hydroelectric turbine blades, Mining, cement plants, hydrofoil legs, anti-seismic applications, helicopter landing grids, penstocks, , hardboard and chipboard press plate, propeller shafting, pulp and paper.
