Stainless Steel 301
Material type: Metal
Type 301 is an austenitic stainless steel with a nominal composition of 17 percent chromium and 7 percent nickel, which provides good strength and ductility when cold worked.It also has excellent corrosion resistance properties.
Process compatibility
Material Color
Silver
Material advantages
301 is well suited to welding, forming and drawing. This high strength grade of steel is available in several conditions or tempers.
Material shortcomings
Type 301 is corrosion resistant in many environments, but the corrosion properties are less than that of 304/304L stainless steel.
Recommended description
In the annealed condition, Type 301 offers the highest level of stretch formability of any stainless steel and in the heavily cold worked condition offers the highest strength level of any 300 series stainless steel. Type 301 is non-magnetic in the annealed condition but becomes magnetic as a result of cold working.
