317L raises molybdenum to 3–4% and chromium to 18–20%, which buys a meaningful increase in pitting resistance over 316L without moving to the cost of 904L or 6-Moly. It is the grade of choice for flue gas desulphurisation, pulp bleaching and acid service where 316L has been shown to pit but the duty does not justify a super-austenitic.
Pitting resistance equivalent. Higher resists chlorides better.
Indexed to 304. Indicative, for specification triage.
Rajgranth Metal & Alloys manufactures, stocks, supplies and exports Stainless Steel 317 and 317L seamless Tubes (UNS S31700 / S31703) from Mumbai. Higher molybdenum than 316, at 3–4%. The step up before super-austenitics. Rajgranth Metal & Alloys has been trading since 1980, is self-funded and debt-free, and despatches most orders from its Mumbai stockyard within two days.

Stainless Steel 317 and 317L is also designated UNS S31700 / S31703, EN 1.4445 / 1.4438, AISI 317 / 317L, JIS SUS317 / SUS317L, GB S31708 / S31703 and Werkstoff X6CrNiMo19-13-4 / X2CrNiMo19-14-4. Quote the designation your specification uses and we will supply to it.
Markedly better pitting resistance than 316L, Good performance in sulphurous and acidic condensate and Retains full austenitic weldability and formability. It is non-magnetic, with excellent weldability and fair machinability, and is used in continuous service in air up to about 870 °C.
Longer lead times than 304 or 316, Still subject to chloride stress corrosion cracking and Cost approaches that of duplex, which often outperforms it. We state these plainly so the grade is chosen for the right service.
