SS 316/316L Seamless Pipes

Manufacturers & Suppliers of Stainless Steel 316/316L Seamless Pipes , UNS S31600/S31603 1.4401/1.4436, Seamless Pipes Metline is a leading manufacturer and supplier of SS 316/316L seamless pipes. Our seamless 316/316L pipes are manufactured in a variety of size and schedule or thicknesses. However, there is a restriction on the manufacturing of large diameter pipe. Generally, seamless 316/316L pipes are available in stock in sizes upto 16". Seamless pipe, as the name suggests, is a pipe without a seam or a weld-joint. Seamless 316/316L stainless steel pipe is made from a solid round steel ‘billet’ which is heated and pushed or pulled over a form until the steel is shaped into a hollow pipe. About 316 Stainless Steel Stainless steel 316 (SS316) is an austenitic chromium-nickel stainless steel containing min. 2.5% of molybdenum which increases general corrosion resistance and especially improves its pitting resistance to chloride ion solutions. The molybdenum addition provides increased strength at elevated temperatures. SS316 is also known as “Mo-Added” version of SS304. Stainless steel 316L (SS316L) is the extra-low carbon version of SS316 that minimizes harmful carbide precipitation during welding. Both SS316 and SS316L have exceptional resistance to corrosion against sulfuric, hydrochloric, acetic, formic, and tartaric acids; as well as against acid sulfates and alkaline chlorides. Stainless Steel 316L pipes and fittings are widely used in exhaust manifolds, heat exchangers, pharmaceutical equipment, cryogenic piping, valve and pump trims, chemical & petrochemical process, pulp and paper industry, and food industry, etc. Production & Stock Range for UNS S31600/S31603, 316/316L Stainless Steel Seamless Pipes Production Details Product Stainless Steel 316/316L Seamless Pipes Outer Diameter Round Pipe : 6~710mm Square Pipes : 10mm x 10mm - 400mm x 400mm Rectangular Pipes: 10mm x 20mm -200mm x 400mm Wall Thickness Round Pipes: 1.0 - 50.00 mm Square Pipes:1.0mm-20mm Rectangular Pipes: 0.6mm-20mm Type Seamless, Welded, ERW, EFW, 100% X-Ray Welded or Fabricated Pipes Length 2m - 5.8m, 6m, 12m Surface Finish Annealed & Pickled, Hot Rolled No.1 Mill Finish, Polished, Mirror, Matte, 240 Grit, 400 Grit, 500 Grit for Stainless Steel Pipes Pipe End Plain End/ Bevel End Groove End Ends Joint with Flange or Fittings Threaded on Two Ends, One End with Coupling, One End with Plastic Cap Marking As Per Client Requirements or Mill Standard Packing OD Not Less Than 273mm: Loose Packing - Piece by Piece OD less than 273mm - In Hexagonal Seaworthy Bundles Packed by Steel Strips On Request Small Sizes May be Nested into Big Sizes Production Method Seamless, Hot Rolled, Cold Drawn, Heat Treated, Impact Tested Trade Term FOB, CFR, CIF, EXW Payment Term T/T, LC Delivery Time 15-45 days (based on quantity) after receiving advanced payment by T/T or LC PREN of Various Grades of Stainless Steels Grade Type Cr Mo N PREN Ferritics 1.4003 - 10.5-12.5 NS 0.030 max 10.5-12.5 1.4016 430 16.0-18.0 NS NS 16.0-18.0 1.4113 434 16.0-18.0 0.9-1.4 NS 19.0-22.6 1.4509 441 17.5-18.5 NS NS 17.5-18.5 1.4521 444 17.0-20.0 1.8-2.5 0.030max 23.0-28.7 Austenitics 1.4301 304 17.5-19.5 NS 0.11max 17.5-20.8 1.4311 304LN 17.5-19.5 NS 0.12-0.22 19.4-23.0 1.4401/4 316/316L 16.5-18.5 2.0-2.5 0.11max 23.1-28.5 1.4435 316L (2.5% min Mo) 17.0-19.0 2.5-3.0 0.11max 25.3-30.7 1.4406 316LN 16.5-18.5 2.0-2.5 0.12-0.22 25.0-30.3 1.4539 904L 19.0-21.0 4.0-5.0 0.15max 32.2-39.9 1.4563 Sanicro 28 24.0-26.0 3.0-4.0 0.11max 35.9-43.0 1.4547 254SMO 19.5-20.5 6.0-7.0 0.18-0.25 42.2-47.6 Duplex 1.4162 Lean Duplex 21.0-22.0 0.1-0.8 0.20-0.25 24.5-28.6 1.4362 2304 22.0-24.0 0.1-0.6 0.05-0.20 23.1-29.2 1.4462 2205 21.0-23.0 2.5-3.5 0.10-0.22 30.8-38.1 1.44102 2507 24.0-26.0 3.0-4.0 0.24-0.35 > 402 Equivalents of 316/316L Stainless Steel Grade Grade UNS No Old British Euronorm Swedish SS Japanese JIS BS En No Name 316 – 316L S31600/S31603 304S11 58E 1.4401 / 1.4436 X5CrNiMo17-12-2 / X3CrNiMo17-13-3 2347 / 2348 SUS 316 – 316L Chemical Composition of UNS S31600/S31603, 1.4401/1.4436, 316 Stainless Steel Seamless Pipes 316 316H 316N 316L 316Ti Ni 10 – 14 10 – 14 10 – 14 10 – 14 10 – 14 Fe Balance Cr 16 – 18 16 – 18 16 – 18 16 – 18 16 – 18 Mo 2 – 3 2 – 3 2 – 3 2 – 3 2 – 3 C 0.08 max 0.10 max 0.03 max 0.03 max 0.08 max Si 0.75 max 0.75 max 0.75 max 0.75 max 0.75 max Mn 2 max 2 max 2 max 2 max 2 max P 0.045 max 0.045 max 0.045 max 0.045 max 0.045 max S 0.030 max 0.030 max 0.030 max 0.030 max 0.030 max N 0.1 max 0.1 max 0.1 max 0.1 max Ti 5 X % (C + N) Mechanical Properties for WNR.

SS 316Ti Seamless Pipes

Manufacturers & Suppliers of Stainless Steel 316Ti Seamless Pipes, 1.4571/UNS S31635 Seamless Pipes Metline is a leading manufacturer and supplier of SS 316Ti seamless pipes. Our seamless 316Ti pipes are manufactured in a variety of size and schedule or thicknesses. However, there is a restriction on the manufacturing of large diameter pipe. Generally, seamless 316Ti pipes are available in stock in sizes upto 16". Seamless pipe, as the name suggests, is a pipe without a seam or a weld-joint. Seamless 316Ti stainless steel pipe is made from a solid round steel ‘billet’ which is heated and pushed or pulled over a form until the steel is shaped into a hollow pipe. About 316Ti Stainless Steel Grade 316Ti stainless steel has been traditionally specified by German engineers and users with the Werkstoff number 1.4571. This grade is essentially a standard carbon 316 type with titanium stabilisation and is similar in principle to the titanium stabilisation of the 304 (1.4301) type to produce 321 (1.4541). The addition of titanium is made to reduce the risk of intergranular corrosion (IC) following heating in the temperature range 425-815C. Stainless Steel 316 is the standard molybdenum-bearing grade, second in importance to SS 304 amongst the austenitic stainless steels. The molybdenum gives SS 316 better overall corrosion resistant properties than Stainless Steel 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. Stainless Steel 316 has excellent forming and welding characteristics. It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. SS 316 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections. SS 316L, the low carbon version of SS 316 and is immune from sensitisation (grain boundary carbide precipitation).SS 316H, with its higher carbon content has application at elevated temperatures, same as SS 316Ti which is a Titanium stabilised grade. SS 316N is nitrogen enhanced with greater strength than SS 316.
