904L Super Austenitic Pipe and Tubing ASTM A312 / A358 Stainless Steel 904L Pipe Supplier, 904L Stainless Steel Seamless Pipe. Contact us to discuss ASME SA312 904L Stainless Steel Pipe and how it can meet your specific needs.

904 alloy (N08904) stainless steel stands as a high-alloy austenitic marvel, engineered to withstand severe corrosion and provide exceptional corrosion resistance.
904L stainless steel is a non-stabilized austenitic stainless steel featuring a low carbon level. This high-alloy stainless steel comes enriched with copper, enhancing its resistance to strong reducing acids like sulfuric acid. Additionally, the steel exhibits exemplary resistance to stress corrosion, cracking, and crevice corrosion. Non-magnetic by nature, 904L stainless steel also boasts outstanding formability, toughness, and superior welding capabilities. The 904L grade is distinguished by its high concentration of valuable elements such as molybdenum and nickel, making it a premium choice for demanding applications.
904L grade stainless steel delivers remarkable resistance to hot seawater and chloride attacks. Thanks to its high nickel content, 904L grade stainless steel excels in resisting stress corrosion cracking. The addition of copper further enhances its resistance to sulfuric acid and other reducing agents, both in corrosive and mild environments. The corrosion resistance of 904L grade steel surpasses that of standard austenitic steels like 316L but falls between super-austenitic steels containing 6% molybdenum. For optimal resistance to stress corrosion cracking in sensitive settings, 904L grade and should undergo solution treatment following cold working.

Certifications

Grade 904L stainless steel tubes boast exceptional resistance to warm seawater and chloride attacks. This remarkable resistance to stress corrosion cracking stems from its high nickel content. Additionally, the infusion of copper enhances its resilience against sulfuric acid and other reducing agents, making it robust under both aggressive and mild conditions.

The corrosion resistance of grade 904L stands between super austenitic grades with 6% molybdenum content and standard 316L austenitic grades. While grade 904L is not as resistant as grades 304L and 310L, which lack molybdenum, it still provides substantial durability. Solution treatment after cold working is essential to achieve maximum resistance against stress corrosion cracking in critical environments.

Heat Resistance

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

Heat Treatment

Grade 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 steel.

Welding

Welding grade 904L stainless steel can be accomplished using all conventional methods. This grade does not necessitate pre-heating or post-weld heat treatments. However, it is susceptible to hot cracking in constrained weldments. Grade 904L electrodes and rods, conforming to AS 1554.6, are recommended for welding.

Fabrication

Grade 904L stainless steel tubes are high-purity steels with low sulfur content, allowing machining through standard methods. These grades can be easily bent to a small radius under cold conditions. While annealing is generally not required, it should be performed under severe stress corrosion cracking conditions.

Applications

Some prominent applications of grade 904L stainless steel tubes include:

• • Wiring in electrostatic precipitators
• • Oil refinery components
• • Seawater cooling devices
• • Gas scrubbing plants
• • Pulp and paper processing industries
• • Acetic, phosphoric, and sulfuric acid processing plants
