Stainless Steel Pipe grades comparison at glance

TYPE 304 / 304L STAINLESS PIPE

  • An austenitic chromium-nickel stainless steel
  • General purpose corrosion resistance
  • Non-magnetic except when cold worked

TYPE 304H STAINLESS PIPE

  • Higher carbon than Type 304 for better high temperature creep properties
  • Corrosion resistance same as Type 304
  • Used in high temperature over 1000 degrees F

TYPE 309S STAINLESS STEEL PIPE

  • Superior heat resisting austenitic stainless steel
  • Good for continuous exposure to 2000 degrees F
  • Slightly better corrosion resistance than Type 304

TYPE 310S STAINLESS STEEL PIPE

  • Superior heat resisting austenitic stainless steel
  • Good for continuous exposure to 2100 degrees F
  • General corrosion resistance better than Type 304 and 309

TYPE 316 / 316L STAINLESS STEEL PIPE

  • An austenitic chromium-nickel stainless steel
  • Improved corrosion and heat resistance
  • Improved corrosion resistance to chlorides

TYPE 317L STAINLESS STEEL PIPE
