MP Jain Co. is a manufacturer and exporter of stainless steel 316 pipe fittings based in India. They produce ASME SA403 grade fittings in sizes ranging from 1/8" to 48" NB according to various international standards. Stainless steel 316 contains molybdenum which gives it improved corrosion resistance over standard stainless, particularly in chloride environments. It can be welded using the same filler rods as the base metal and has excellent mechanical properties.
