S31800 stainless steel introduction
S31800 stainless steel is a duplex stainless steel with excellent corrosion resistance and high strength. Its chemical composition is between austenite and ferrite, combining the advantages of both, and is widely used in chemical, petroleum, natural gas and other fields.
Main parameter of S31800 Stainless Steel
Chemical composition (typical value) :
- Carbon (C) : ≤ 0.03%
- Silicon (Si) : ≤ 1.00%
- Manganese (Mn) : ≤ 2.00%
- Phosphorus (P) : ≤ 0.030%
- Sulfur (S) : ≤ 0.020%
- Chromium (Cr) : 21.0-23.0%
- Nickel (Ni) : 4.5-6.5%
- Molybdenum (Mo) : 2.5-3.5%
- Nitrogen (N) : 0.08-0.20%
Mechanical properties of S31800 Stainless Steel
- Tensile strength: ≥ 620 MPa
- Yield strength: ≥ 450 MPa
- Elongation: ≥ 25%
- Hardness: ≤ 290 HB
- Physical properties:
- Density: 7.8 g/cm³
- Melting point: 1420-1465 °C
- Coefficient of thermal expansion: 13.7 × 10⁻⁶ /K (20-100 °C)
