Stainles Steel 321/321H Flanges

Stainless steel 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. Harsh Steel stocks a wide variety of stainless steel flanges.

As an acclaimed undertaking of the business, Calico Metal is included in offering an unfathomable cluster of Stainless Steel 321/321H Flanges as a maker, exporter, stockiest and supplier to our household and worldwide customers. Stainless Steel 321/321H is the low carbon rendition of 317. It doesn't require post-weld toughening as is widely utilized as a part of substantial gage segments (over around 6mm). Stainless Steel Grade 304H 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.

321/321H 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. 321/321H is non-magnetic in the annealed condition but may become slightly magnetic as a result of welding. 321/321H 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.

317L 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. 321/321H is resistant to sulfuric acid concentrations up to 5 percent at temperatures as high as 120°F (49°C).

Applications
