ASTM A312 304 stainless steel pipe contains 16% to 24% chromium, as well as small amounts of carbon and manganese. The most common form is 18-8 stainless steel. It contains 18% chromium and 8% nickel. 316 stainless steel pipe has almost the same physical and mechanical properties as 304 stainless steel. The main difference is that 316 stainless steel contains about 2% to 3% molybdenum. Additives improve corrosion resistance, especially against chlorides and other industrial solvents.
