Alloy 20 Pipe Fittings Manufacturer

Global Steel is a notable supplier, stockist, and manufacturer of Alloy 20 Pipe Fittings, these fittings are made utilizing supreme quality raw materials.   

It is a nickel-iron chrome austenitic alloy developed for maximum resistance to acids, especially sulfuric acid, as well as resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides and sulfuric, phosphoric, and nitric acids. It contains niobium for stabilizing against sensitization and intergranular corrosion.   

Alloy 20, also known as Carpenter 20, is a nickel-iron-chromium austenitic alloy that has superior resistance to acid attack, specifically sulfuric acid. It exhibits resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides and sulfuric, phosphoric, and nitric acids. Niobium is added to reduce sensitization and related intergranular corrosion.

The properties of these alloy fittings include general corrosion resistance to sulfuric acid, also they are resistance to chloride stress corrosion cracking, and Excels in resisting corrosion to hot sulfuric acids, Because of their excellent mechanical properties and fabricability, these pipe fittings are used in many industrial applications, these fittings have minimal carbide precipitation during welding,

These Alloy 20 Pipe Fittings are used in several industrial applications which include Plastics and synthetic fiber production, chemical and petroleum processing equipment, mixing tanks, heat exchangers, and process piping Our Alloy 20 steel provides a remedy for stress corrosion cracking, which can develop when stainless steel is exposed to chloride solutions. Carbon, chromium, copper, iron, manganese, molybdenum, nickel, phosphorous, silicon, and sulfur make up its composition. These Pipe fittings are tested before they are sent to the clients to ensure their productivity.
