It is used in several industrial applications and those are including food industries, chemical plants, petrochemical industries, fertilizer plants, oil refineries, sugar mills industries, pharmaceuticals industries, industrial machineries, textile machineries, seawater equipment, power generations, specialty chemicals, pulp & paper, food & beverages processing, explosives, air pollution control, etc.

Stainless steel 317 Instrumentation Valves material is the austenitic nickel and chromium-based stainless steel that is having good resistance to corrosion ability. The high molybdenum content is enhancing the material’s very good pitting resistance properties. This material is the common 300 series material that is possessing very good tensile strength and creeps strength properties at the elevated temperature. Stainless steel 317L is the low carbon austenitic nickel and chromium-based SS. It can be made in used in the applications where it is not possible to anneal after the welding process and also at where the corrosion resistant is looked-for. It is giving very good resistance to oxidation at continuous and intermittent service at temperature 1700 deg F and 1600 deg F respectively

SS 317/317L Instrumentation Valves are tested carefully by conducting tests like IGC & PMI tests, flattening tests, chemical tests, etc.
