ASTM B462 - Flanges

ASTM A182 flange offer users a combination of nickel, chromium, molybdenum, and copper which provides good general corrosion resistance. Alloy 20 flanges are best suited for mid-range corrosion use better than steel alloys. Alloy 20 was designed specifically 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.


Scope And Manufacturing

ASTM B462 specification refers to Alloy 20 Flanges intended for corrosive high temperature service. A sufficient discard shall be made from each ingot to secure freedom from injurious piping and undue segregation. Requirements for forging (done by hammering, pressing, rolling, extruding, or upsetting), hot working, and heat treatment are detailed. The material shall conform to the chemical composition prescribed for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, copper, columbium, tantalum, nitrogen, iron, cobalt, tungsten, vanadium, titanium, zirconium, aluminum, yttrium, and cerium. The material shall meet the requirements specified for the mechanical properties including tensile strength, yield strength, and elongation. The forgings shall conform to the specified sizes and shapes.
