SS flanges are reputed and well known across the globe for their reliability and quality. Our flanges division encompasses an integrated forge shop which manufacturers all types of pipe fittings i.e. flanges, butt welding fittings (ASME/ ANSI, EN, DIN, AFNOR, AWWA, GOST, BS, JIS, AS, MSS, SA, UNIÂ etc.) as well as forged bars.
SS Flanges are made up of different stainless steel materials. There are different grades to the stainless steel depending on the material composition and the mechanical properties vary. Matrix Metal & Alloys is a leading manufacturer and supplier of these SS flanges. The ASTM A182 Weld Neck Flange are made up of a super austenitic material that has good corrosion resistant properties with low carbon in its composition. The applications include utility scrubber assemblies. SS flanges are also used in acid production and fertilizer production plants due to its corrosion resistance.
