Stainless steels are known as high-alloy steels. They are classified into ferritic, austenitic, and martensitic steels based on their crystalline structure.
Grade 310S stainless steel is superior to 304 or 309 stainless steel in most environments because it has high nickel and chromium content. It exhibits high corrosion resistance and strength in temperatures up to 1149°C (2100°F). The following datasheet provides more details about grade 310S stainless steel.

Seamless coiled tubing is the preferred choice in critical applications, eliminating the risk of impurities often associated with welded alternatives.
With more than a decade of experience exporting stainless steel tube products globally, our production history spans over ten years. We utilize two continuous production lines equipped with advanced manufacturing systems. By incorporating world-class online bright annealing technology, we perform inline softening treatments on stainless steel pipes. Furthermore, our strict quality control process covers compression testing, flaring, bending tests, 100% hardness validation, tensile testing, and airtightness testing to ensure reliable quality for global distribution.
Grade 310S contains higher nickel and chromium content, giving it exceptional corrosion resistance and high strength at elevated service temperatures up to 1149°C (2100°F).
Our stainless steel coiled tubes are produced strictly in accordance with ASTM A269 and ASTM A249 standards, ensuring high quality and safety for instrumentation and pressure applications.
We manufacture coiled tubing with outer diameters ranging from 6.52mm up to 20mm, and wall thicknesses from 0.2mm up to 2mm, with custom lengths spanning from 300 to 3500 meters per coil.
Seamless coiled tubing is the optimal choice for critical environments because it lacks welded seams, reducing the risk of impurities, improving system reliability, enhancing corrosion resistance, and minimizing connection fittings to prevent leakage.
All tubes undergo rigorous quality testing, including inline bright annealing, compression tests, flaring and bending tests, 100% hardness validation, tensile strength tests, and airtightness verification.
They are widely applied in petrochemical systems, geothermal and desalination plants, food and beverage processing, boilers, heat exchangers, refrigeration equipment, and oil and gas piping systems.
