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.

For high corrosion resistant applications, Alloy 625 Welded tubing is a preferred option, widely utilized to manufacture aircraft components. Alloy 625 exhaust tubing is also highly useful for high-quality tubing systems in oil & gas processing, food processing, and power generation industries.

Coil tubes are offered in sizes from 6.35 to 25.4 mm in outer diameter and wall thicknesses from 0.2 to 2 mm. Generally, these lines of tubing are available in continuous lengths up to 3500 meters. The utilization of straighteners makes installation faster and more efficient across various industry verticals. Seamless coiled tubes are customizable to fulfill your specific system layout requirements.

• We are a primary manufacturer of stainless steel coiled tubes and pipes, ensuring rigorous internal quality control.
• Seamless capabilities allow continuous lengths exceeding 3500M per coil.
• Extensive processing capabilities including bending, stretching, saw cutting, stamping, and high-precision polishing.
• Utilization of advanced bright annealing technology to achieve online softening treatment.
• 100% rigorous product testing: compression, flaring, bending, hardness, stretching, and air tightness tests.

Seamless coiled tubing is the first choice in critical applications because it eliminates the risk of impurities that are often associated with welded seams. It provides:

• Custom lengths tailored to application requirements.
• Enhanced system safety and long-term reliability.
• Greater corrosion resistance under harsh environments.
• Fewer fittings, reducing the risk of leak paths and mechanical failure.
• Reduced installation labor and material overhead costs.
