Giredhi 316 ndiyo yakajairwa molybdenum-bearing giredhi, yechipiri mukukosha kusvika 304 pakati peaustenitic stainless steels.Iyo molybdenum inopa 316 zvirinani zvakazara zvisingaite ngura pane Giredhi 304, kunyanya kukwirisa kupinza gomba uye kukoromoka kwevhu munzvimbo dzechloride.
Simbi isina Stainless - Giredhi 316L - Zvivakwa, Kugadzirwa uye Zvishandiso (UNS S31603)
Giredhi 316L, iyo yakaderera kabhoni vhezheni ye316 uye haina kudzivirirwa kubva mukunzwa (grain boundary carbide precipitation).Saka inoshandiswa zvakanyanya mune inorema gauge welded zvikamu (pamusoro pe6mm).Iko kazhinji hapana mutsauko wemutengo unokosheswa pakati pe316 ne316L simbi isina tsvina.
Iyo austenitic chimiro chinopawo aya mamakisi kusimba kwakanyanya, kunyangwe pasi kusvika kune cryogenic tembiricha.
Kana ichienzaniswa nechromium-nickel austenitic simbi isina tsvina, 316L simbi isina tsvina inopa yakakwira inokambaira, kushushikana kwekuputika uye kusimba kusimba pakupisa kwakakwira.
