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 than 304 or 309 stainless steel in most environments, because it has high nickel and chromium content. It has high corrosion resistance and strength in temperatures up to 1149°C (2100°F). The following datasheet gives more details about grade 310S stainless steel.

★ Seamless coiled tubing is a no. 1 choice in most of the critical applications as there is no risk of impurities that are often associated with welded coiled tubing.
We have experience to export stainless steel tube products for more than ten years.
Grade 310S contains high nickel and chromium content, offering higher corrosion resistance and mechanical strength in environments with temperatures reaching up to 1149°C (2100°F).
It is widely used in refrigeration equipment, evaporators, condensers, gas-liquid delivery systems, heat exchangers, petrochemical processing, and oil and gas piping setups.
Seamless coiled tubing eliminates the risk of impurities commonly associated with welded seams. It offers better system safety, higher corrosion resistance, and fewer fittings, which reduces the potential for leak failures.
Outer diameters range from 6.52mm to 20mm with wall thicknesses between 0.2mm and 2mm. Lengths can extend from 300 to 3500 meters per coil depending on customer requests.
Our coiled tubes are manufactured under ASTM A269/A249 standards. Available designations include TP304, TP316L, 310S, 2205, Monel 400, Hastelloy, and Inconel alloys.
