We have been in the pursuit of creating a broad and complete set of wholesome products line that is a sustainable and profitable; which incorporates designs and features that accommodate requisites of diverse industries. We, Rexton Steel & Alloys, an ISO 9001:2000 company strive to offer products that reduce cost and raise output. We are a manufacturer, supplier and exporter of Stainless Steel 347 / 347H Flanges that are austenitic flanges with traces of Niobium which thwarts the formation of Chromium carbides near grain boundary.
This, in turn, prevents intergranular corrosion. ASME SA182 SS 347 Slip-On Flanges are used with heavy wear exhaust systems and tubes connecting industrial boilers as they are resistant to high oxidation and impart greater toughness at cryogenic temperatures. Our SS UNS S34709 Weld Neck Flanges are manufactured with added Carbon for added toughness and refined high temperature creep properties in the aerospace, petroleum refining and high-temperature steam services. Also We offer wide range of Stainless Steel ASTM A182 347 Flanges such as SS 347 Slip On Flanges, SS 347H Weld Neck Flanges, SS 347 Socket Weld Flanges, SS 347H Blind Flanges, SS 347 Orifice Flanges, SS 347H Spectacle Blind Flanges, SS 347 Screwed / Threaded Flanges, SS 347H Reducing Flanges, SS 347 Ring Type Joint Flanges (RTJ) etc.
Stainless Steel 347 Flanges is an internal or external rib, or lip, for potency, or for a direct, as the flange on the end of a pipe, steam cylinder, etc. These Stainless Steel 347H Flanges can as well be a ring or plate to make a rim at the end of a pipe when fixed firmly to the pipe. Meanwhile, also known as UNS S34700 and UNS S34709 respectively, Our SS 347 Flanges and SS 347H Flanges are discussed and fall under the ASME and ASTM standards, except otherwise indicated. These flanges are available in different types such as SS 347 Slip On Flanges, SS 347H Blind Flanges, SS 347 Weld Neck Flanges, SS 347H Socket Weld Flanges, SS 347 Orifice Flanges, SS 347H Spectacle Blind Flanges, SS 347 Screwed / Threaded Flanges, SS 347H Reducing Flanges, SS 347 Ring Type Joint Flanges (RTJ), and more.
Regarding diverse evaluations, we offer these Flanges in various sorts, for example, SS Slip On Flanges, SS Blind Flanges, SS Weld Neck Flanges, SS Socket Weld Flanges, SS Spectacle Blind Flanges, SS Screwed/Threaded Flanges, SS Reducing Flanges, and SS Ring Type Joint Flanges (RTJ). In the interim, our costs of such spines are set remembering customers prerequisite.
As for national and global nature of crude materials, we likewise offer these SS 347/347H Flanges in tweaked sizes and thicknesses according to particular requests by our regarded customers at business sector driving costs.
