ASME SA213 TP904L Seamless Tube | Bright Annealed 904L Stainless Steel Tube

ASME SA213 TP904L Seamless Stainless Steel Tube

ASME SA213 TP904L seamless tubes are high-alloy austenitic stainless steel tubes designed for corrosive and high-temperature environments.

Grade 904L stainless steel (UNS N08904) contains high levels of nickel, chromium, molybdenum, and copper, providing outstanding resistance to:

• Strong acids such as sulfuric acid

• Pitting and crevice corrosion

• Stress corrosion cracking

• Chloride corrosion

Because of these properties, SA213 TP904L bright annealed tubes are widely used in heat exchangers, chemical processing equipment, boilers, and offshore industries.

ASME SA213 TP904L Tube Standard

ASME SA213 / ASTM A213 covers seamless ferritic and austenitic alloy steel tubes for boilers, superheaters, and heat exchangers.

The specification includes various grades such as:

• TP304 / TP304L

• TP316 / TP316L

• TP321

• TP347

• TP904L

These tubes are typically supplied in bright annealed or solution annealed condition to ensure excellent corrosion resistance and surface finish.
