Unimix Metal Cooperation stands out as a leading manufacturer, exporter, and supplier of Stainless Steel 317 Flanges, crafted from high-grade alloy and offered in various sizes and types at affordable prices. Alloy 317 Flanges, an austenitic chromium-nickel stainless steel, provides exceptional corrosion resistance.
We are renowned for producing SS 317 Socket Weld Flanges, widely utilized in flue-gas desulfurization systems, chemical process vessels, petrochemical industries, pulp and paper production, and power generation condensers. Our UNS S31700 SS Orifice Flanges, made with molybdenum, resist pitting and serve as reliable, leak-proof seals for pipe endings in the breweries, water, and sugar industries.
The aging treatment of UNS S31700 | WNR. 1.4449 Ring Joint Type Flanges occurs at such a low temperature that it ensures no significant distortion.
