Alloy 20 Fasteners

Alloy 20 Industrial Fasteners, Alloy 20 Bolts, Alloy DIN 2.4660 Studs , Nickel Alloy 20 Screws, Carpenter 20 Heavy Hex Nuts Wholesaler Suppliers in India.

Ranfit Metal & Alloys is a known manufacturer of Alloy 20 Fasteners, which has outstanding resistance to both reducing and oxidizing media. Cold forming of Alloy 20 Nuts is the preferred method of forming. Alloy 20 Bolts exhibits excellent resistance to corrosive attack by seawater under stagnant and flowing conditions. Alloy 20 Stud Bolts can resist the grain boundary precipitate form when jointing heat affected zone, this performance made it can applied in many kinds of chemical processing. The omission of tungsten and a reduction in the iron content of Alloy 20 Washers is meant to increase thermal stability. The heat treatment of Alloy 20 Screws is carried out at 2050 Degree F (1120 Degree C) followed by water quench or rapid air cool. A hold time at the annealing temperature of 10 minutes to 30 minutes in Alloy 20 Round Bars is recommended, depending on the thickness of the structure.

Alloy 20 Studs should not be used in service temperatures above 1250 Degree F due to the formation of detrimental phases which form above this temperature. Because of high work-hardening rate of Alloy 20 Rods, only low surface-cutting speeds are possible compared with low-alloy standard austenitic stainless steel. Alloy UNS N08020 Fasteners is often chosen to solve stress corrosion cracking problems, which may occur with other stainless steel. Alloy WNR 2.4660 Fasteners excels in resisting corrosion to hot sulfuric acids and minimal carbide precipitation during welding.
