What is the difference between stainless steel grade SS304 and SUS304?

Comparison: SS304 vs. SUS304 Stainless Steel Grades

Overview:

The primary distinction between SS304 and SUS304 stainless steel grades lies in their specifications. SS304 adheres to standard specifications, whereas SUS304 is defined by the Japanese Industrial Standards (JIS).

Composition:

  • SS304: Contains 18-20% chromium and 8-10.5% nickel.
  • SUS304: Chromium content ranges from 16-18%, with nickel content ranging from 7-9%.

Corrosion Resistance:

Slight variations in chromium and nickel content render SUS304 more resistant to corrosion, particularly in highly corrosive settings like marine applications or saltwater environments.

Mechanical Properties - SUS304:

  • Density: 8000 kg/m³
  • Young’s Modulus: 190 GPa
  • Tensile Strength: 520 MPa
  • Yield Strength: 240 MPa
  • Poisson's Ratio: 0.27-0.30
  • Hardness (Brinell): 88 HB

Mechanical Properties - SS304:

  • Density: 7860 kg/m³
  • Young’s Modulus: 190-210 GPa
  • Tensile Strength: 400-510 MPa
  • Yield Strength: 205-245 MPa
  • Poisson's Ratio: 0.26
  • Hardness (Brinell): 160 HB
