Alloy 20 ASTM B462 Threaded Flanges, Werkstoff No 2.4660 Alloy Socket Weld Flanges, ANSI B16.5, ANSI B16.47, B16.48, BS4504, BS 10, EN-1092 Alloy 20 Forged Flanges, Alloy 20 Lapped joint Flanges, Manufacturer Of UNS N08020 Alloy Plate Flange in China.

We offer wide range of Alloy 20 ASTM B462 Flanges such as Alloy 20 Slip On Flanges, Alloy 20 Weld Neck Flanges, Alloy 20 Socket Weld Flanges, Alloy 20 Blind Flanges, Alloy 20 Orifice Flanges, Alloy 20 Spectacle Blind Flanges, Alloy 20 Screwed / Threaded Flanges, Alloy 20 Reducing Flanges, Alloy 20 Ring Type Joint Flanges (RTJ) etc. Carpenter 20 and 20CB-3, Alloy 20 flanges offer users a combination of nickel, chromium, molybdenum, and copper which provides good general corrosion resistance. UNS N08020 flanges are best suited for mid-range corrosion use ¨C better than steel alloys but not at the level of high performance nickel based alloys like Hastelloy C276.

Werkstoff No 2.4660 flanges provide good performance in hot sulfuric acid, specifically they offer good resistance to stress-corrosion cracking in boiling sulfuric acid at specific range of 20% to 40% concentration, as well as general sulfuric acid resistance. ANSI B16.5 Alloy 20 flange offers solid acid protection and will perform better than Duplex or even Monel, but for high temperature and high concentration acids, you may need to look to Inconel or Hastelloy fasteners. In addition, Alloy 20 flanges also show useful resistance to phosphoric acid and nitric acid. UNS N08020 Alloy 20 flange is a nickel alloy that was specifically designed to withstand the harsh environment of hot sulfuric acid but also performs well in a variety of other acids. Alloy 20 flanges are an ideal choice when you don¡¯t need the corrosion resistance power and price-tag of high performance nickel alloys like Hastelloy C276; but you need something that will give you more protection than 316 stainless steel or even a Super Duplex 2507 stainless steel.
