Rajveer Stainless and Alloys is one of the leading Manufacturer, Supplier and Exporter of Stainless Steel 309H Welded Tubes that is being made up from High Quality of Standard Raw Materials. ASTM A249 TP 309H Stainless Steel Welded Tubes are generally optimised for oxidation and elevated temperature corrosion resistance. These Stainless Steel ASTM A269 TP 309H Welded Tubes as well have excellent mechanical characteristics, to a certain extent because of their austenitic configuration and to a certain extent because of certain alloying constituents. The most general type of response in ASTM A249 TP 309H SS Welded Tubes is the precipitation of non-attractive phases, which, apart from lowering the corrosion resistance by taking advantageous alloying constituents (especially chromium), leads to a decreased toughness or ductility of the product, in particular at room temperature.
Designed as per international and national standards, these UNS S30909 Welded Tubes are offered in customized length sizes and shapes to our esteemed clients. Also referred as WNR 1.4833, these tubes are available at best possible rates in the market. .
We are an authorized Dealer, as well as Supplier of Stainless Steel 309H Welded Tubes of various Approved Manufacturing companies like Nippon Steel, Sandvik, Sanyo Special Steel, Kobe Steel, Schoeller Bleckmann, Salzgitter Mannesmann, Tubacex etc.
