Alloy 20 Fasteners is also known as Incoloy 20 fasteners and Carpenter 20 fasteners. Alloy 20 Stainless Steel Bolts are a nickel-iron-chromium alloy, which is austenitic. Alloy 20 Nuts is a super alloy that includes molybdenum and Copper. Alloy 20 Screws are most commonly done by MIG, TIG and also by SAW (submerged arc welding). The welding of Alloy 20 is done by E320LR for SAW and ER320LR for MIG and TIG. When Alloy 20 is welded to dissimilar alloys like 316 or even to higher alloys like Alloy 22 and C276, ENiCrMo-3 can be used for SAW and for MIG and TIG, AWS ERNiCrMo-3 can be used.

Table of Content


The Density of Alloy 20 Bolts is 0.291 lb/in3 (8.05 g/cm3). It has an Elongation at Break of 41%. Alloy 20 Hex Head bolt is used in process piping, heat exchangers and mixing tanks. Such fasteners made from Alloy 20 are also used in the processing of heavy chemicals, plastics and pharmaceuticals. Alloy 20 Bolts chemical composition is as follows: Iron, Fe 35. Nickel, Ni 32-38. Chromium, Cr 19-21. Copper, Cu 3-4. Manganese, Mn ≤2. Molybdenum, Mo 2-3. Niobium, Nb ≤1. Silicon, Si ≤1. Carbon, C ≤0.07. Phosphorous, P ≤0.045 and Sulfur, S ≤0.035. By using traditional methods, it is possible to form Alloy 20 by cold-working or hot-working. Alloy 20 is in big demand in the production of chemicals, solvents, pharmaceuticals, explosives, gasoline and synthetic materials. Alloy 20 Threaded Rod is also used in reactor vessels and in chemical process piping. It is also used in petrochemical process equipment.

 

We manufacture bolts, nuts, anti-theft bolts & nuts, studs, foundation bolts, U-bolts, plain and spring washers in Alloy 20 material in India. Alloy 20 Socket Head Cap Screws are most popular fastener & can come with large cylindrical heads that have recessed hex-shaped drives. Due to this quality these Alloy 20 Screws are mainly in demand by the applications where clearance is limited, and sockets and wrenches can't be used. The size of a Alloy 20 metric screws or bolt is specified as diameter, pitch and length, in millimeters (millimeters is abbreviated "mm"). The size of Alloy 20 nuts, will appear as diameter and pitch.
