904L Super Austenitic Pipe and Tubing ASTM A312 / A358 Stainless Steel 904L Pipe Supplier. We provide 904L Stainless Steel Seamless Pipe. Contact us for ASME SA312 904L Stainless Steel Pipe.

904 alloy (N08904) stainless steel is a premium high-alloy austenitic material designed to withstand extreme corrosion, offering exceptional resistance.
904L stainless steel is an advanced non-stabilized austenitic grade with low carbon content. This high-alloy steel includes copper, enhancing its resistance to strong reducing acids such as sulfuric acid. Additionally, it offers superior resistance to stress corrosion, cracking, and crevice corrosion. 904L is non-magnetic, boasting outstanding formability, toughness, and welding capabilities. This grade's high concentration of valuable elements like molybdenum and nickel speaks to its exceptional quality.
904L grade stainless steel excels in resisting hot seawater and chloride attacks. Thanks to its high nickel content, 904L withstands stress corrosion cracking remarkably well. The addition of copper further improves resistance to sulfuric acid and other reducing agents in both aggressive and mild environments. Its corrosion resistance sits between super austenitic steels with 6% molybdenum and standard 316L austenitic steel. Unlike grades 304L and 310L, which lack molybdenum, 904L needs solution treatment after cold working to maximize stress corrosion resistance in sensitive conditions.

Company Profile

All 904L type stainless steel supplied by Daxun Alloys adheres to standard manufacturing criteria such as ASTM, EN, and more. This stainless steel type is non-magnetic under all conditions and boasts exceptional formability and welding properties. Thanks to its austenitic structure, it remains highly robust even at cryogenic temperatures. The elevated chromium content fosters a passive film, shielding the material from corrosive environments. Compared to other molybdenum-containing stainless steels like 316L and 317L, 904L stands out for its superior resistance to ferrite and sigma phase precipitation during cooling and welding. The low carbon content minimizes the risk of intergranular corrosion during these processes. It can withstand temperatures up to 450°C. Our 904L pipe stock is identified as ASTM A312 UNS N08904, SB 677 UNS N08904, and Werkstoff No. 1.4539.

Certifications

The 904L grade stainless steel tube is renowned for its exceptional resistance to warm seawater and chloride attacks. This remarkable resistance is attributed to the high nickel content within its composition. Additionally, the inclusion of copper enhances its resistance to sulfuric acid and other reducing agents, making it resilient in both aggressive and mild conditions.

904L grade's corrosion resistance stands intermediate between super austenitic grades, which contain 6% molybdenum, and standard 316L austenitic grades. Unlike grades 304L and 310L, which are molybdenum-free, 904L falls slightly short in resistance. To achieve optimal stress corrosion cracking resistance in critical environments, post-cold work solution treatment is essential.

Heat Resistance

904L stainless steel exhibits commendable oxidation resistance. However, its structural stability diminishes at temperatures exceeding 400°C.

Heat Treatment

904L stainless steel can undergo solution heat treatment at temperatures ranging from 1090 to 1175°C, followed by rapid cooling. This thermal treatment is effective for hardening the grades.

Welding

Welding 904L stainless steel is feasible with all conventional methods and does not necessitate pre-heat or post-weld heat treatments. Despite this, 904L may experience hot cracking in constrained weldments. For welding, use 904L electrodes and rods as specified by AS 1554.6.

Fabrication

904L stainless steel tubes are noteworthy for their high purity and low sulfur content. They are compatible with standard machining methods and can be easily bent to a small radius under cold conditions. While subsequent annealing is generally unnecessary, it is advisable if the fabrication involves severe stress corrosion cracking conditions.

Applications

Grade 904L stainless steel tubes find their major applications in the following areas:

• Wiring in electrostatic precipitators
• Components for oil refineries
• Seawater cooling devices
• Gas scrubbing plants
• Pulp and paper processing industries
• Plants processing acetic, phosphoric, and sulfuric acids
