The Stainless Steel 201 Angle is an austenitic alloy primarily made of iron, containing about 16–18% chromium, 3.5–5.5% manganese, 4–5.5% nickel, along with trace elements like nitrogen and carbon. It boasts excellent toughness, moderate resistance to corrosion, and high yield strength. Typical mechanical properties include a tensile strength of around 520 MPa, yield strength of 275 MPa, and good elongation of about 45%. SS 201 is more affordable than 300-series grades due to its lower nickel content, yet it still performs well for many structural and decorative applications.
