Multi Metals India is one of the leading SS flange manufacturers in India, supplying weld neck, slip-on, blind, socket weld, and threaded types to piping contractors and fabrication shops. Stock covers 304, 304L, 316, and 316L grades, machined to match bolt circle diameters and bore sizes used on standard piping runs. Flanges from this range connect directly with stainless steel pipes and fittings already installed on a project, so bolt hole alignment and face finish get checked before dispatch. Grade choice is usually based on the service medium and the amount of chloride exposure the joint will experience.
Chromium content above 16% gives these flanges their base corrosion resistance. Flanges are produced to ASTM A182 material grade and ASME B16.5 dimensional standards, the specification followed by most stainless steel flange manufacturers in India. 316 and 316L grades have an additional 2 to 3% of molybdenum to aid in chloride-heavy or acidic environments. Nickel is in the 8 to 14% range depending on grade and allows ductility during welding. The tensile strength of 304/304L is around a minimum of 515 MPa, with yield strength around 205 MPa. 316L has slightly higher numbers because of an addition of molybdenum.
Face types include raised face, flat face, and ring-type joint, selected based on gasket type and system pressure. Machined faces reduce leak risk at the bolted joint. A consistent bore finish keeps flow resistance low across the connection too. These flanges go into chemical processing lines, water treatment plants, pharmaceutical piping, marine equipment, and food processing systems, wherever a pipeline needs a bolted joint that can be opened for maintenance. As a stainless steel flanges supplier, stock is held across common sizes, so smaller orders don’t wait behind a full production run, and pairing them with stainless steel fittings on the same order keeps lead times shorter.
