Chemical Composition: S32205 stainless steel, also known as Duplex 2205, belongs to the duplex stainless steel family, renowned for its superior corrosion resistance and high strength. The chemical composition of S32205 typically includes:
Chromium (Cr): 22-23%
Nickel (Ni): 4.5-6.5%
Molybdenum (Mo): 3-3.5%
Nitrogen (N): 0.14-0.2%
Manganese (Mn): 2% max
Silicon (Si): 1% max
Phosphorus (P): 0.03% max
Sulfur (S): 0.02% max
The presence of these elements imparts exceptional corrosion resistance and mechanical properties to S32205 stainless steel.
2. Mechanical Properties: S32205 stainless steel exhibits remarkable mechanical properties that contribute to its widespread usage. Some key mechanical properties include:Tensile Strength: S32205 offers a minimum tensile strength of 620 MPa (90 ksi).
Yield Strength: It provides a minimum yield strength of 450 MPa (65 ksi).
Elongation: S32205 demonstrates a minimum elongation of 25% in 50 mm.
Hardness: Typically, S32205 has a maximum hardness of 31 HRC.
These mechanical properties make S32205 stainless steel suitable for demanding applications where high strength and corrosion resistance are critical.
