Intsimbi engenastainless 316,316L,316H

I-316 yinqanaba eliqhelekileyo lokuthwala i-molybdenum, okwesibini ngokubaluleka kwi-304 phakathi kweentsimbi ezingenasici ze-austenitic. I-molybdenum inika iipropati ezingama-316 ezingcono zokuxhathisa umhlwa kune-304, ingakumbi ukuxhathisa okuphezulu kwimingxuma kunye nokuhlwa kwemingxuma kwiindawo ezinekloridi. Ineempawu ezibalaseleyo zokubumba kunye ne-welding. Iqhekezwa ngokulula okanye iqulunqwe yaziinxalenye ezahlukeneyo zezicelo kushishino, ulwakhiwo, kunye nemimandla yezothutho. I-316 nayo ineempawu ezibalaseleyo ze-welding. I-post-weld annealing ayifuni xa udibanisa amacandelo amancinci.

I-316L, i-carbon version ephantsi ye-316 kwaye ikhuselekile kwi-sensitization (i-grain boundary carbide precipitation). Ngaloo ndlela isetyenziswa kakhulu kwigeyiji enzima edityanisiweyo (ngaphezulu kwe-6mm).
I-316H, enomxholo wayo ophezulu wekhabhoni inesicelo kumaqondo obushushu aphakamileyo, njengoko kwenza ibakala elizinzileyo le-316Ti.
Isakhiwo se-austenitic sikwanika la mabanga ukuqina okugqwesileyo, kude kube phantsi ukuya kumaqondo obushushu e-cryogenic.
