Material                                                          Description

Aluminized Steel coated with aluminum/silicon on both sides. Provides strength and heat protection

200-Series

Material                                                          Description

201 General purpose stainless steel, very economical

202 General purpose stainless steel, very economical. Has more Chromium (Cr), Manganese (Mn), and Nickel (Ni) than 201

300-Series

Material                                                          Description

301 Highly ductile stainless steel that has excellent weldability, strength and corrosion resistance

302 Higher strength (due to increased carbon content) than 304, but with the same corrosion resistance

303 Strength and corrosion resistance characteristics similar to 304, but with sulfur and phosphorus for free machining

304 Most common grade of stainless steel, with 18/8 (18% chromium, 8% nickel). Excellent strength and corrosion resistance

309 Strength and corrosion resistance similar to 304, but with better heat resistance

316 Marine-grade stainless steel that contains molybdenum to prevent specific forms of corrosion (especially chloride)

400-Series

Material                                                          Description

409 Very economical stainless steel, used principally in automotive exhaust systems

410 High strength stainless steel with excellent wear-resistance

420 High strength, cutlery grade stainless steel, with excellent polishability

430 Good formability, but temperature and corrosion resistance is reduced. Widely used for automotive trim applications

431 Excellent impact strength at high hardness levels. Used in a variety of aircraft and general industrial applications.

439 Higher chromium content than 409 for increased temperature, corrosion, and oxidation resistance

441 Higher grade version of 409, stabilized with titanium and columbium for increased oxidation, creep resistance, and improved formability
