316/316L Sanitary Stainless Steel Tubing - 3-1220mm OD, 0.5-50mm Thickness, Seamless & Welded
Our 316/316L sanitary stainless steel tubing offers superior corrosion resistance, excellent formability, and outstanding weldability. Available in both seamless and welded configurations with various surface finishes to meet diverse industrial requirements.
Alloy 316/316L is a molybdenum-bearing austenitic stainless steel with enhanced corrosion resistance properties compared to 304 grade. The higher nickel and molybdenum content provides superior performance against pitting and crevice corrosion in chloride environments, along with excellent elevated temperature tensile, creep, and stress-rupture strengths.
| Surface | Characteristics & Application |
|---|---|
| NO.1 | Hot-rolled surface, annealed and pickled; used as cold-rolling material, industrial tanks, and chemical devices |
| NO.2D | Cold-rolled, annealed and pickled without skinpassing; suitable for automobile parts, building materials, and piping |
| NO.2B | Better brightness and flatness than NO.2D; improved mechanical properties for comprehensive applications |
| NO.3 | Polished with abrasive belt grit #100-#120; discontinuous coarse striations; used for building ornaments, electrical appliances, and kitchen utensils |
| NO.4 | Polished with abrasive belt grit #150-#180; thinner striations than NO.3; suitable for bathtubs, building ornaments, electrical appliances, kitchen utensils, and food processing equipment |
| HL | Polished with abrasive belt grit #150-320 on NO.4 finish; continuous streaks; primarily used for building ornaments, elevators, and door frontal plates |
| BA | Cold rolled, bright annealed and skin passed; excellent brightness and mirror-like reflectivity; used for electrical appliances, mirrors, kitchen apparatus, and ornament materials |
