The mechanical properties of 316S11 stainless steel include:
– Tensile strength: 485 MPa (70,300 psi)
– Yield strength: 170 MPa (24,700 psi)
– Elongation at break: 40%
– Hardness, Brinell: 217
– Modulus of elasticity: 200 GPa (29,000 ksi)
The corrosion resistance of 316S11 stainless steel is excellent in a wide range of environments, including those containing chlorides and other corrosive agents. This makes it suitable for use in marine and coastal applications, as well as in industrial settings where corrosion is a concern. The addition of molybdenum to the alloy enhances its resistance to pitting and crevice corrosion, further extending its useful lifespan in harsh conditions.
