Common Stainless Steel Alloys

Below is a brief overlook at common stainless steel alloys. Click on alloy number of each to learn more about the actual composition and common uses for that particular alloy.

303 – Best for uses requiring extensive machining with good resistance to corrosion.

304 – The most commonly used stainless steel alloy, valued for it’s ease of forming, corrosion resistance and welding properties.

309– Most often used in applications requiring strength, corrosion and high temperature resistance.

316– Second only to 304 in popularity, this alloy contains molybdenum however provides better corrosion resistance than the number one alloy.

409 – This steel alloy is used where high temperature, good corrosion resistance and formability is required.

410 – Provides corrosion and scaling resistance with good impact strength, maintains excellent mechanical properties when heated.

416 – A chromium steel always magnetic, provides excellent machinability, not recommended for applications requiring welding.

430 – A non-hardenable steel alloy with formability and good resistance to corrosion.
