Stainless Steel Grades for Angle

304 (Austenitic)

One of the most widely used general-purpose stainless steels. It possesses an excellent combination of strength, corrosion resistance and fabricates well. To reduce carbide precipitation when welding, use 304L for its lower-carbon content.

316 (Austenitic)

Superior corrosion resistance compared to other 300 series alloys when used in used harsh corrosive environments (ex. sea water, chemicals, etc.). To reduce carbide precipitation when welding, use 316L for its lower-carbon content.

321 (Austenitic)

Titanium stabilized stainless steel to prevent intergranular formation of chromium carbide. It exhibits strength characteristics superior to those of 304 stainless, thus making it best suited for parts which cannot be subsequently annealed.

410 (Martensitic)

The lowest alloy content of the three general-purpose types. It is a heat-treatable chromium type used for highly stressed parts needing the combination of strength and corrosion resistance.

409 (Ferritic)

The lowest chromium content of the stainless steels, 409 combines good elevated temperature corrosion resistance with medium strength, good formability, and overall cost.

430 (Ferritic)

A general-purpose non-heat-treatable chromium type used for highly polished trim applications in mild atmospheres. Its strengths are in ductility, formability, good corrosion and oxidation resistance, thermal conductivity and finish quality.
