Stainless Steel Alloy 17-4 PH Flangs

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 17-4 PH Flanges as a maker, exporter, stockiest and supplier to our household and worldwide customers. Stainless Steel 17-4 PH 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.

17-4 PH 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.

17-4 PH 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. 17-4 PH is resistant to sulfuric acid concentrations up to 5 percent at temperatures as high as 120°F (49°C).

Applications

  • Aerospace – piston engine manifolds
  • Chemical Processing
  • Expansion Joints
  • Food Processing – equipment and storage
  • Petroleum Refining – polythionic acid service
  • Waste Treatment – thermal oxidizers

Benefits

  • Higher creep stress and rupture properties when compared with 304
  • Ideal for high temperature service
  • Overcomes sensitization and intergranular corrosion concerns
  • Can be used in elevated temperature applications for ASME Boiler and Pressure Vessel Code applications
  • Due to stabilisation the material offers better overall corrosion resistance when compared to 304/304L
  • Excellent mechanical properties
