904L is a non-stabilised low carbon high alloy austenitic stainless steel. The addition of copper to this grade gives it greatly improved resistance to strong reducing acids, particularly sulphuric acid. It is also highly resistant to chloride attack - both pitting / crevice corrosion and stress corrosion cracking.
This grade is non-magnetic in all conditions and has excellent weldability and formability. The austenitic structure also gives this grade excellent toughness, even down to cryogenic temperatures.
904L does have very substantial contents of the high cost ingredients nickel and molybdenum. Many of the applications in which this grade has previously performed well can now be fulfilled at lower cost by duplex stainless steel 2205 (S31803 or S32205), so it is used less commonly than in the past.
These properties are specified for flat rolled product (plate, sheet and coil) in ASTM B625. Similar but not necessarily identical properties are specified for other products such as pipe, tube and bar in their respective specifications.

904L is a low-carbon, high-alloy austenitic stainless steel. The addition of copper gives it exceptional resistance to strong reducing acids like sulphuric acid. It also features high resistance to chloride pitting, crevice corrosion, and stress corrosion cracking.
Seamless coiled tubing is preferred for critical applications because it eliminates the risk of impurities often found in welded seams. This provides superior system safety, higher pressure capabilities, and better long-term reliability in highly corrosive environments.
Coiled tubing is manufactured in a wide variety of grades, including standard TP304, TP304L, TP316, TP316L, and 201, as well as high-performance alloys such as Alloy 625, Alloy 825, Duplex 2205, and 904L.
Outer diameters typically range from 6.25mm to 25.4mm, with wall thicknesses between 0.2mm and 2mm. Continuous lengths can be customized and supplied in coils ranging from 300 meters up to 3500 meters depending on diameter and thickness specifications.
Stainless steel coil tubes are widely applied in petrochemical, natural gas, geothermal, aerospace, oil and gas, food and beverage processing, boilers, heat exchangers, and instrumentation systems.
To ensure high quality, tubes are subjected to comprehensive testing including flaring, bending, 100% hardness checks, tensile tests, air tightness tests, and online bright annealing softening treatments.
