Our 904L Stainless Steel Tubing is a high-alloy, super-austenitic stainless steel with an extremely low carbon content (≤0.02%) and high proportions of chromium (19%-23%) and nickel (23%-28%), resulting in excellent corrosion resistance. This material is particularly suitable for highly corrosive environments such as sulfuric, phosphoric, and acetic acids, and can withstand temperatures up to 400°C. We offer a full range of 904L stainless steel pipe specifications and support custom fabrication to meet a variety of corrosion-resistant and high-temperature resistant application requirements. Please contact us for more information and samples.
Key Characteristics & Advantages
Superior Corrosion Resistance
Excellent resistance to uniform corrosion, especially in sulfuric, phosphoric, and acetic acids. Outstanding resistance to chloride-induced pitting and crevice corrosion.
Stress Corrosion Cracking (SCC) Resistance
Highly resistant to stress corrosion cracking in chloride-bearing environments.
Ease of Fabrication
Despite its high strength, it possesses good formability and weldability (use matching filler metals like ER385 or 625 for harsh services).
