Chemical Composition:

JIS G4305 SUS305 boasts a well-balanced chemical composition that ensures superior performance. Its key elements include:

· Carbon (C) ≤ 0.12%

· Silicon (Si) ≤ 1.0%

· Manganese (Mn) ≤ 2.0%

· Chromium (Cr) 17.0% - 19.0%

· Phosphorus (P) ≤ 0.045%

· Sulfur (S) ≤ 0.030%

· Nickel (Ni) 10.5% - 13.0%

This composition, enriched with higher nickel content compared to SUS304, imparts exceptional corrosion resistance and enhanced formability.

Mechanical Properties:

SUS305 cold rolled stainless steel plate exhibits impressive mechanical properties, suitable for rigorous working conditions:

· Yield Strength (YS): ≥ 175 MPa

· Tensile Strength (TS): ≥ 480 MPa

· Elongation (EL): ≥ 40%

· Hardness (Hv): ≤ 200

These properties, coupled with its high ductility and low work hardening rate, make SUS305 ideal for intricate forming and shaping processes.

Heat Treatment State:

SUS305 stainless steel plates are typically supplied in the annealed and solution-annealed state, denoted as NO.1, 2D, or 2B finishes. This heat treatment ensures optimal internal stress relief, enhancing formability and corrosion resistance.

Available Production Sizes:

TJC Steel Group offers a comprehensive range of SUS305 cold rolled stainless steel plates to cater to diverse customer requirements. Standard plate sizes include:

· Thickness: 0.3 mm to 6.0 mm (custom sizes available upon request)
