Caliper Overseas is a reliable SS 321 Forged Fittings manufacturer and supplier in India, that provides forged fittings designed for strength and long lasting performance. 321 is titanium stabilised austenitic stainless steel that is suitable for applications where high temperatures and corrosive condition exist. These fittings are produced through a precision forging process, which improves their mechanical strength, corrosion resistance and durability, especially in conditions prone to intergranular corrosion.
These fittings comply with global standards such as ASTM A182/ASME SA182, ASME 16.11, and MSS SP-79, 83, 95, and 97. Available in socket weld and threaded types, they come in sizes from 1/8" to 4" NB and meet dimensional standards like ASME/ANSI B16.9 and MSS-SP-43. With pressure ratings from Class 2000 to 9000, they are manufactured in seamless, welded, or fabricated forms. Each fitting is carefully packaged to prevent damage during transit.
