As an acclaimed try of the business, K M D Steel And Tube is associated with offering an unfathomable pack of Stainless Steel 321/321H Flanges as a manufacturers, exporter, stockiest and supplier to our family and by and large customers. Composite 321 (UNS S32100) is titanium settled austenitic Stainless Steel Flanges with phenomenal general disintegration restriction. Composite 321H (UNS S32109) Stainless Steel Flanges is the higher carbon (0.04 - 0.10) change of the mix.
As to appraisals, 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 reviewing customers basic.
As for national and overall nature of foul materials, we correspondingly offer these SS 321/321H Flanges in changed sizes and thicknesses according to explicit requests by our regarded customers at business territory driving costs. The packaging for the products are done with best attention because we know the challenges faced while import and export of product and hence we make sure that the products are delivered in good conditions without any damages.
