Quality 316 Stainless Steel Seamless Pipe from China Manufacturer
316 Stainless Steel Seamless Pipe is an austenitic stainless steel pipe made from grade 316 stainless steel, which contains 16–18% chromium, 10–14% nickel, and 2–3% molybdenum. The seamless construction, achieved through an extrusion process where a solid billet is heated, pierced, and drawn into a hollow pipe, ensures a uniform structure without a welded seam.
316 Stainless Steel Seamless Pipe Specifications
316 Stainless Steel Seamless Pipes boast excellent performance and high degree of resistance to corrosion due to the stainless steel construction and added molybdenum content which offers superior resistance to difficult conditions.
| Category | Details |
|---|---|
| Characteristics | Austenitic stainless steel with molybdenum (2-3%), offering enhanced corrosion resistance and strength. Low carbon (316L variant) reduces carbide precipitation during welding. Excellent toughness and ductility. |
| Surface Treatment | Typically supplied with a mill finish (annealed and pickled). Optional finishes include polished (e.g., 600-1200 grit), brushed, or custom coatings depending on application needs. |
| Dimensions and Specifications | Outer Diameter: ½” to 16” (common seamless range). Wall Thickness: Schedules 5S to XXS (e.g., Sch 10, 40, 80). Length: Standard 6m or custom cut. Conforms to ASTM A312, ASME SA312, etc. |
| Corrosion Resistance | Superior resistance to pitting and crevice corrosion in chloride environments (e.g., marine, chemical). Resistant to acids (sulfuric, acetic) and potable water up to 1000 mg/L chlorides at ambient temperatures. Susceptible to stress corrosion cracking above 60¡ãC in high chloride conditions. |
| Mechanical Properties | Yield Strength: ≥205 MPa (min). Tensile Strength: ≥515 MPa (min). Elongation: ≥40%. Hardness: ≤95 HRB. Excellent toughness even at cryogenic temperatures. |
| Processability | Excellent formability and weldability. Can be cold drawn, rolled, or brake formed. Seamless pipes are precision-manufactured, requiring no post-weld annealing for thin sections (316L preferred for thicker welds). |
| Applications | Marine (piping, exhausts), chemical processing (tanks, pressure vessels), food/pharmaceutical (hygienic equipment), oil & gas, pulp/paper, architectural (in corrosive environments). |
| Standards | ASTM A312 (seamless/welded pipes), ASME SA312, UNS S31600 (316), UNS S31603 (316L), DIN 1.4401/1.4404, ISO 2604, EN 10216-5, API specifications where applicable. |
