904 alloy (N08904) stainless steel is a high-alloy austenitic marvel designed to endure severe corrosion. It boasts exceptional corrosion resistance.
904L stainless steel is a non-stabilized austenitic stainless steel with a minimal carbon content. This high alloy steel includes copper, enhancing its resistance to potent reducing acids such as sulfuric acid. Additionally, it is resistant to stress corrosion, cracking, and crevice corrosion. 904L stainless steel is non-magnetic and exhibits extraordinary formability, robustness, and welding capacities. The 904L grade is rich in premium elements like molybdenum and nickel.
904L grade stainless steel demonstrates remarkable resistance to hot seawater and chloride assaults. Due to its high nickel content, 904L grade stainless steel excels in resisting stress corrosion cracking. The inclusion of copper further boosts resilience against sulfuric acid and other reducing agents. In terms of corrosion resistance, 904L falls between super austenitic steels with 6% molybdenum and standard 316L austenitic steel. Compared to grades 304L and 310L, which lack molybdenum, 904L is more susceptible. To achieve peak stress corrosion cracking resistance in sensitive environments, it must undergo solution treatment post cold working.

Company Profile

All 904L type stainless steel supplied by Jiangsu Daxun Alloy Co., Ltd. adheres to rigorous manufacturing standards such as ASTM, EN, and more. This exceptional stainless steel exhibits non-magnetic properties in all conditions, coupled with remarkable formability and welding characteristics. Thanks to its austenitic structure, 904L stainless steel displays extraordinary durability even at cryogenic temperatures. The high chromium content fosters a passive film that shields the material from corrosive environments. When 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. With a maximum service temperature of 450°C, our 904L pipe stock is designated as ASTM A312 UNS N08904, SB 677 UNS N08904, and Werkstoff No. 1.4539.

Certifications

Grade 904L stainless steel tubes exhibit unparalleled resistance to warm seawater and chloride-induced corrosion. This exceptional durability results from the high nickel content within its composition, which also fortifies the steel against stress corrosion cracking. The integration of copper further enhances its resistance to sulfuric acid and other reducing agents, ensuring reliability in both severe and moderate environments.

The corrosion resistance of grade 904L stainless steel is superior to standard 316L austenitic grades and stands between super austenitic grades with 6% molybdenum. However, it offers less resistance than grades 304L and 310L, which are molybdenum-free. For optimal stress corrosion cracking resistance in critical conditions, grade 904L must undergo solution treatment after cold working.

Heat Resistance

Grade 904L stainless steels deliver commendable oxidation resistance. Nevertheless, their structural integrity diminishes at elevated temperatures, particularly beyond 400°C, limiting their high-temperature applications.

Heat Treatment

Grade 904L stainless steels are amenable to solution heat-treatment at temperatures ranging from 1090°C to 1175°C, followed by rapid cooling. This thermal treatment is ideal for hardening these grades, thereby enhancing their mechanical properties and corrosion resistance.

Welding

Welding grade 904L stainless steels can be effectively executed using all conventional methods without necessitating pre-heat or post-weld heat treatments. Despite this, there's a risk of hot cracking in constrained weldments. Employing grade 904L electrodes and rods, as per AS 1554.6 standards, is recommended for achieving optimal welding outcomes.

Fabrication

Grade 904L stainless steel tubes are characterized by their high purity and low sulfur content, making them suitable for various machining methods. These grades can be easily bent to small radii under cold conditions. While annealing is not typically required post-fabrication, it should be considered when operating under extreme stress corrosion conditions.

Applications

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
