As an acclaimed undertaking of the business, Vision Alloys is included in offering an unfathomable cluster of Stainless Steel 347/347H Flanges as a maker, exporter, stockiest and supplier to our household and worldwide customers. Stainless Steel 347 (UNS S34700) is columbium balanced out austenitic Stainless Steel Flanges with great general corrosion resistance and fairly better resistance in solid oxidizing conditions than 321 (UNS S32100). Alloy 347H (UNS S3409) Stainless Steel Flanges is the higher carbon (0.04 – 0.10) rendition of the alloy.
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.
