Stainless Steel 202 welded Tubes: manufacturer, stockist and exporter in Mumbai, India
Rajgranth Metal & Alloys manufactures, stocks, supplies and exports Stainless Steel 202 welded Tubes (UNS S20200) from Mumbai. Chromium-manganese-nickel austenitic grade. A lower-cost alternative to 304 for dry, indoor and decorative use. Rajgranth Metal & Alloys has been trading since 1980, is self-funded and debt-free, and despatches most orders from its Mumbai stockyard within two days.
What is 202?
Grade 202 (UNS S20200) is a chromium-manganese-nickel austenitic stainless steel. Manganese and nitrogen replace part of the nickel found in 304, which lowers the price and the exposure to nickel price swings, and gives a higher yield strength in the annealed condition. It takes a bright polish and forms well in tube and sheet, which is why it is widely used for kitchenware, furniture, decorative tube, interior architectural trim and appliance parts. Its corrosion resistance is lower than 304 and 316, so it belongs in dry, indoor and mildly humid service, not in coastal, chloride or chemical environments.
Designations
Stainless Steel 202 is also designated UNS S20200, EN 1.4373, AISI 202, JIS SUS202 and Werkstoff X12CrMnNiN18-9-5. Quote the designation your specification uses and we will supply to it.
SS 202 composition and mechanical properties
Per ASTM A240 for UNS S20200: carbon 0.15 max, manganese 7.50 – 10.00, silicon 1.00 max, phosphorus 0.060 max, sulphur 0.030 max, chromium 17.00 – 19.00, nickel 4.00 – 6.00 and nitrogen 0.25 max percent. Annealed mechanical limits: tensile strength 515 MPa minimum, yield strength (0.2% offset) 260 MPa minimum, elongation in 50 mm 40% minimum, hardness 95 HRB maximum (217 HBW). Confirm the composition on the mill test certificate supplied with the material.
Why choose 202 welded Tubes
Lower cost than 304, because manganese and nitrogen replace part of the nickel, Higher annealed yield strength than 304 (260 MPa minimum to ASTM A240), Takes a bright, even polish for decorative and appliance finishes and Forms and rolls well into tube, pipe and sheet products for indoor use. It is non-magnetic, with good weldability and fair machinability, and is used in continuous service in air up to about 815 °C.
Limitations to specify around
Lower corrosion resistance than 304 and 316, Not suitable for coastal, outdoor-marine, chloride or chemical-process service, Poorer deep-drawing behaviour than 304 and Chemistry varies between mills, so confirm it against the mill test certificate. We state these plainly so the grade is chosen for the right service.
