JIS SPA-C weathering steel

SPA-C is a common material in weathering steel. The delivery status of steel mills is mostly in the form of hot-rolled coils, and those above 20 mm are usually ex-factory flat sheets.

Weathering Steel SPA-C has good atmospheric corrosion resistance and is a Japanese material standard for excellent atmospheric corrosion resistance steel plates, sheets and strips. The atmospheric corrosion resistance of SPA-C is significantly better than carbon steel with or without copper added in most environments.

SPA-C alloy composition:
Silicon: 0.25
Manganese: 0.20
Phosphorus: 0.70
Copper: 0.25
Chromium: 0.30
Nickel: ≤0.65

SPA-C mechanical properties:
Steel grade: SPA-C
Yield strength: ≥ 325 MPa
Tensile strength: ≥ 450 MPa
Elongation: ≥ 26

Weathering Steel SPA-C Applications:
SPA-C weathering steel is widely used in railway carriages, container production, bridge construction, construction, etc.
