Stainless Steel 202 is a low-nickel, manganese-strengthened austenitic alloy that performs similarly to 304 in mild, indoor environments at a lower material cost.
Stainless Steel 202 is a chromium-manganese-nickel austenitic alloy, like 201, developed as a nickel-conserving alternative to 304. It offers good strength, formability, and weldability at lower cost, but weaker corrosion resistance than 304, especially against chlorides and pitting.
Stainless Steel 202 is not recommended for marine, outdoor, or heavy chemical exposure, but is well suited to indoor architectural trim, restaurant and kitchen equipment, hose clamps, and general hardware where budget outweighs corrosion demands.
