Kencotube is one of the leading manufacturers & trader of high quality of Alloy 20 Forged Fittings that resists pitting and chloride ion corrosion and its copper content protects it from sulfuric acid. Alloy 20 Forged Threaded Fittings is commonly performed via, TIG, MIG as well as submerged arc welding (SAW). Alloy 20 Forged Socket Weld Fittings also proves adequate resistance to nitric acid, concentrated sulfuric acid, dilute acetic acid and naphtha. Alloy 20 Forged Threaded Elbow Fittings is often chosen to solve stress corrosion cracking problems, which may occur with 316L stainless. Alloy 20 Forged Socket Weld Elbow Fittings is not a stainless steel but a nickel alloy (ASTM), which is often chosen to solve stress corrosion cracking problems and may occur with Stainless Steel 316L.
INCOLOY Alloy 20 Forged Fittings is normally used in the annealed condition, where annealing should be carried out in the range of 1800 Degree – 1850 Degree F (982 Degree C – 1010 Degree C),for a time commensurate with section size. Overall, Alloy 20 Forged Threaded Tee Pipe Fittings is an excellent alternative to more expensive metals with similar applications. Alloy 20 Forged Socket Weld Tee Pipe Fittings find its uses in exotic and highly-demanding applications, such as in the turbine blades of jet engines, in spacecraft, and in nuclear reactors. UNS N08020 Forged Fittings is non-hardening in nature which helps it to prevent cracking when the alloy is exposed to high temperature or welded.
