Open Die Forging 420 Steel Turbine Blade Steam Turbine Blades

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.

Heat treatment:
Normalized / Annealed / Quenched / tempered

Surface Treatment:
painting,plating,polishing,black oxide,transparent anti-rust oil,sand blasting

Quality control:
UT,MT,RT,PT,chemical composition test,mechanical property test,etc.

Inspection:
1, Raw material certificate(material chemical composition)
2, Heat treatment sheet report
3, Dimension inspection report
4, UT test report

Delivery condition:
