Alpha Overseas trades SS 317L Flanges, which can be forged in the 1700 Degree F – 2200 Degree F range. Alloy 317L Flanges has a superior corrosion resistance in special applications where it is desired to reduce contamination to a minimum. Grade 317L Flanges is similar to 316 stainless steel but provides improved resistance to atmospheric corrosion, to many organic and inorganic chemicals and to food and beverages. Type 317L Flanges is tougher than grade 304 stainless steel with a long stringy chip; however, using chip breakers is recommended. Stainless Steel 317L Slip On Flanges is a low carbon corrosion resistant austenitic chromium-nickel-molybdenum stainless steel. Increased levels of chromium, molybdenum and nickel in 317L Stainless Steel Flanges when compared to 316L stainless steel, it improves resistance to chloride pitting and general corrosion. Stainless Steel 317L Ring Type Joint Flanges is an advanced metal wire used to wrap your own coils for rebuildable atomisers. SS 317L Socket Weld Flanges offers even better creep deformation characteristics and mechanical resistance to high temperatures when compared with conventional stainless steels.
