Ko te Alloy 317LMN (UNS S31726) he kowiri tira austenitic chromium-nickel-molybdenum me te parenga waikura pai ake i te 316L me te 317L. Ko te ihirangi molybdenum teitei ake, me te taapiri o te hauota, e whakarato ana i te koranu me te kaha ake o te aukati i te waikura, ina koa i roto i te ratonga waikawa waikawa kei roto. Ko te whakakotahitanga o te molybdenum me te hauota ka pai ake te aukati o nga koranu ki te rua me te waikura kapiti.
Ko te ihirangi hauota o te Alloy 317LMN ka mahi hei kaihoko whakakaha ka nui ake te kaha o te tuku mai i te 317L .Ko te Alloy 317LMN he karaehe waro iti e taea ai te whakamahi i roto i te ahua-a-wea kore i te rerenga chromium carbide i runga i nga rohe o te witi.
Ko te Alloy 317LMN he kore-aukume i roto i te ahua o te annealed. Kaore e taea te whakapakeke ma te wera wera, ma te mahi makariri anake. Ko te koranu ka taea te paihere me te tukatuka ma nga tikanga hanga toa.
