Unifit Metal Alloys is a distinguished supplier of Socket Weld Pipe Flanges, whichis a type of austenitic steel with intermediate to high corrosion protection. Alloy 20 Socket Weld Flanges is high alloyed, acid-proof steel that has been created to withstand corrosion in dilute sulphuric acid. This is super austenitic steel with intermediate to high corrosion protection in a variety of industrial environments. It is high-alloy austenitic steel designed for use in the process sector under extreme corrosion circumstances. It is austenitic steel designed for use under extreme corrosion circumstances, with excellent resilience to acidic assaults such as sulphuric, phosphoric, and acetic acid. This is an austenitic steel standard with intermediate to high corrosion resistance, and its high alloy makeup provides excellent resistance to pitting and corrosion in a variety of settings.

Titanium Alloy Socket Weld Flanges is an austenitic grade with very high corrosion resistance that is widely used in the chemical and petrochemical industries for managing moderately concentrated sulphuric acid.This steel's highly alloyed chemistry of nickel and molybdenum offers better chloride stress corrosion cracking, pitting, and overall corrosion protection to molybdenum enhanced steels. They have better hardness even at cryogenic temperatures because of their austenitic structure.This steel is austenitic steel that can be used to avoid hot saltwater corrosion and chloride-based assault. They are much more resistant to pitting corrosion, stress corrosion cracking, and pocket corrosion than other steels. They have better hardness even at cryogenic temperatures because of their austenitic structure.

In many settings, the chromium, molybdenum, and nickel composition of Stainless Steel Socket Weld Flanges provide superior chloride pitting corrosion protection than other stainless. It is frequently used in chemical industry process equipment, pulp and paper industry bleaching equipment, petrochemical industry, flue gas purification, desalination, and other applications. Other advantages include non-magnetic characteristics, improved corrosion resistance, and resilience to sulphuric, phosphoric, and acetic acids. This steel is frequently used in chemical plants, oil refineries, petrochemical plants, bleaching containers for the paper industry, combustion gas desulfurization plants, marine water, sulphuric and phosphoric acid applications, and so on.
