Austenitic Seamless Stainless Steel ASTM A213 904L N08904 1.4539 pipe tubeAustenitic Seamless Stainless Steel ASTM A213 904L N08904 1.4539 pipe tube

ASTM A213/ASME SA213 covers low alloy steel pipes and minimum-wall-thickness, seamless ferritic and austenitic steel, boiler and super-heater tubes and austenitic steel heat-exchanger tubes, designated Grades TP304,TP304H,TP304L,TP310S, TP310HCbN, TP316, TP316H, TP316L etc.

Grades TP304H, TP309H, TP309HCb, TP310H, TP310HCb, TP310HCbN, TP316H, TP321H, TP347H, TP347HFG (fine grained) and TP348H are modifications of Grades TP304, TP309S, TP309Cb, TP310S, TP310Cb, TP316, TP321, TP347, and TP348, and are intended for high-temperature service, such as for superheaters and reheaters.

For ASTM A213 Seamless Tubes with diameters less than 1/8 in. [3.2 mm] in inside diameter or 0.015 in. [0.4 mm] in thickness,mechanical property requirements won’t apply. Tube with other dimensions may be furnished comply with other requirements.

904L Stainless Steel Tube | UNS N08904 | WNR 1.4539


UNS NO8904, commonly known as 904L, is a low carbon high alloy austenitic stainless steel which is widely used in applications where the corrosion properties of AISI 316L and AISI 317L are not adequate.

The addition of copper to this grade gives it corrosion resistant properties superior to the conventional chrome nickel stainless steels, in particular to sulphuric, phosphoric and acetic acids. However, there is limited use with hydrochloric acids. It also has a high resistance to pitting in chloride solutions, a high resistance to both crevice and stress corrosion cracking. Alloy 904L performs better than other austenitic stainless steels due to the higher alloying of nickel and molybdenum.

The grade is non-magnetic in all conditions and has excellent formability and weldability. The austenitic structure also gives this grade excellent toughness, even down to cryogenic temperatures.

The high chromium content promotes and maintains a passive film which protects the material in many corrosive environments.904L has a greater resistance to precipitation of ferrite and sigma phases on cooling and welding than other stainless steels containing molybdenum such as 316L and 317L. There is no risk of intercrystalline corrosion on cooling or welding due to the low carbon content. Its maximum service temperature is at 450°C.

This grade is particularly useful in control and instrumentation tubing applications where 316 and 317L are not suitable.
