904L Super Austenitic Pipe and Tubing - ASTM A312 / A358. Your trusted supplier for 904L Stainless Steel Seamless Pipe. Contact us for premium ASME SA312 904L Stainless Steel Pipes.

904 alloy (N08904) stainless steel is a high-alloy austenitic marvel engineered for extreme corrosion resistance. Its robust composition ensures superior durability and longevity.
904L stainless steel is a non-stabilized austenitic stainless steel with low carbon content. Enriched with copper, this high alloy thrives in strong reducing acids such as sulfuric acid. It resists stress corrosion, cracking, and crevice corrosion. Non-magnetic, 904L excels in formability, toughness, and welding. The high levels of molybdenum and nickel enhance its premium properties.
904L grade stainless steel offers exceptional resistance to hot seawater and chloride attack. Its high nickel content ensures superior stress corrosion cracking resistance. Copper addition boosts resistance to sulfuric acid and other reducing agents, whether in harsh or mild environments. The corrosion resistance lands between super austenitic steels with 6% molybdenum and standard 316L austenitic steel. While more susceptible than 304L and 310L grades, it achieves peak resistance to stress corrosion cracking when solution-treated after cold working.

Company Profile

All 904L type stainless steel supplied by Daxun Alloys meets stringent standard manufacturing criteria such as ASTM, EN, and more. This high-quality stainless steel is non-magnetic under all conditions and boasts exceptional formability and welding properties. Due to its austenitic structure, it remains remarkably robust, even at cryogenic temperatures. The elevated chromium content fosters and sustains a passive film that shields the material from corrosive environments. When compared to other molybdenum-bearing stainless steels like 316L and 317L, 904L exhibits superior resistance to ferrite and sigma phase precipitation during cooling and welding. The low carbon content further negates the risk of intergranular corrosion during these processes. The maximum operating temperature is 450°C. Our 904L pipe stock is available under specifications such as ASTM A312 UNS N08904, SB 677 UNS N08904, and Werkstoff No. 1.4539. Purchase premium products from trusted manufacturers of 904L SS Seamless Pipe, ASTM B677 TP 904L SS Seamless Pipe, ASTM B674 TP 904L SS Pipe, SS 904L Welded Pipe, and 904L SS Pipe.

Certifications

Grade 904L stainless steel tubes exhibit outstanding resistance to warm seawater and chloride-induced corrosion. The superior stress corrosion cracking resistance is attributed to the high nickel content. Additionally, the incorporation of copper enhances resistance to sulfuric acid and other reducing agents, providing exceptional durability in both harsh and moderate environments.

The corrosion resistance of grade 904L is intermediate between super austenitic grades containing 6% molybdenum and standard 316L austenitic grades. While it is less resistant compared to molybdenum-free grades like 304L and 310L, grade 904L requires solution treatment post-cold working to maximize stress corrosion cracking resistance in critical conditions.

Heat Resistance

Grade 904L stainless steels offer good oxidation resistance. However, the structural integrity of this grade diminishes at elevated temperatures, especially beyond 400°C.

Heat Treatment

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

Welding

The welding of grade 904L stainless steel can be carried out using all conventional methods. This grade does not require pre-heating or post-weld heat treatments. However, it is susceptible to hot cracking in constrained weldments. Grade 904L electrodes and rods must be used for welding according to AS 1554.6.

Fabrication

Grade 904L stainless steel tubes are characterized by high purity and low sulfur content, allowing for standard machining methods. These tubes can be easily bent to a small radius under cold conditions. Although annealing is generally not necessary, it should be conducted when fabrication involves severe stress corrosion cracking conditions.

Applications

Key applications of grade 904L stainless steel tubes include:

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