Gayatri Tubes is known for the manufacturing, exporting, and supplying of theAlloy Steel F22 Flanges. We provide these flanges in high quality and proper testing so that it can comply with the industrial standards. We make sure that we make a just a minimal use of the hydrochloric acids. Alloy Steel F22 Flanges are much better in working than the other austenitic steel materials because they involve a high usage of the nickel and molybdenum in their alloy. The raw materials are also of high quality and are cost effective as well.
The melting operation is conducted through the use of carbon ferrochromium. These flanges have added chromium which is available in a concentration of 11 to 18%of carbon which has added nickel. The flanges that we provide are hardened with the help of the process of heat treatment and have an excellent resistance against the corrosion as well. They find their usage in a large number of industries such as the cutlery industry, surgical instrument industry, wrench and turbines industry, etc.
The blind flanges of the Alloy Steel F22 Flanges provide a high resistance against the corrosion especially against the environments that contain acid. The lap joints of the Alloy Steel F22 Flanges have a lot of characteristics because of its copper content such as the resistive nature against the corrosive acids.
The ring joints of the Alloy Steel F22 Flanges have content of carbon in their composition which gives them an increase in the weldability and also provides a resistance against the wear and tear caused by the extensive use of them.
The spectate blind variants of the Alloy Steel F22 Flanges has a composition of mixture of copper, nickel, and molybdenum that gives them a superior resistance against the sulfuric acid and the spacer flanges of the Alloy Steel F22 Flanges makes them resistant against the corrosion due to its development procedure. The class of products that we supply in the category of Alloy Steel F22 Flanges is tested well before they are manufactured so that we can ensure that they are fit for the usage in various industries.
