Stainles Steel 440 Flanges

Stainless steel 440 flanges from 15NB (1/2”) to 600NB (24”) in Weld neck. Slip-on, Blind, Lap joint, Bossed, Socket Weld and Threaded according to the following standards are available.

As an acclaimed undertaking of the business, Calico Metal is included in offering an unfathomable cluster of Stainless Steel 440 Flanges as a maker, exporter, stockiest and supplier to our household and worldwide customers. Stainless Steel 440 is the low carbon rendition of 310. It doesn't require post-weld toughening as is widely utilized as a part of substantial gage segments (over around 6mm). Stainless Steel Grade 440 with its higher carbon content discovers application at elevated temperatures.

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.

440 is a molybdenum bearing, low carbon content "L" grade austenitic stainless steel that provides improved corrosion resistance over 304L and 316L stainless steels. The low carbon provides resistance to sensitization during welding and other thermal processes. 440 is non-magnetic in the annealed condition but may become slightly magnetic as a result of welding. 440 has excellent corrosion resistance in a wide range of chemicals, especially in acidic chloride environments such as those encountered in pulp and paper mills. Increased levels of chromium, nickel and molybdenum compared to 316L stainless steel improve resistance to chloride pitting and general corrosion.

440 has excellent corrosion resistance in a wide range of chemicals, especially in acidic chloride environments such as those encountered in pulp and paper mills. Increased levels of chromium, nickel and molybdenum compared to 316L stainless steel improve resistance to chloride pitting and general corrosion. Resistance increases with molybdenum alloy content. 440 is resistant to sulfuric acid concentrations up to 5 percent at temperatures as high as 120°F (49°C).
