304 Stainless Steel Pipes and Tubes Corrosion Resistance
Excellent in a wide range of atmospheric environments and many corrosive media. Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 600C. Considered resistant to potable water with up to about 200mg/L chlorides at ambient temperatures, reducing to about 150mg/L at 600C.304 Stainless Steel Pipes and Tubes Heat Resistance
Good oxidation resistance in intermittent service to 8700C and in continuous service to 9250C. Continuous use of 304 in the 425-8600C range is not recommended if subsequent aqueous corrosion resistance is important. Grade 304L is more resistant to carbide precipitation and can be heated into the above temperature range.
Grade 304H has higher strength at elevated temperatures so is often used for structural and pressure-containing applications at temperatures above about 5000C and up to about 8000C. 304H will become sensitised in the temperature range of 425-8600C; this is not a problem for high temperature applications, but will result in reduced aqueous corrosion resistance.
