It contains the lowest chromium content of all stainless steels and has excellent oxidation resistance in high temperatures and good welding performance,which is the least expensive steel and a low cost option for corrosion resistant stainless steel.


304 stainless tail pipe

Grade 304 was popular used for tail pipe for recent years.304 grade stainless is tough and nearly impervious to rusting, because it has around 20% chromium and 10% nickel content and is the highest quality stainless steel used in the automotive world.
