I-SUS410 / SUS420J2 / SUS430 ubuhlalu beentsimbi ezingenasici Uthelekiso：
SUS410: IMartensite imele ibakala lensimbi, elinamandla aphezulu kunye nobulukhuni obuphezulu (amandla kazibuthe); ukuxhathisa ukubola, ukungakulungeli ukusetyenziswa kwiindawo ezinobungozi obukhulu; Umxholo ophantsi we-C, ukusebenza kakuhle, kwaye umphezulu unokuba lukhuni ngonyango lobushushu.
SUS420J2: IMartensite imele ibakala lensimbi, elinamandla aphezulu kunye nobulukhuni obuphezulu (amandla kazibuthe); ukunganyangeki kakuhle, ukungasebenzi kakuhle kunye nokuqina, kunye nokumelana kakuhle; inokunyangwa ubushushu ukuphucula iipropathi zoomatshini. Isetyenziswa ngokubanzi xa kusetyenzwa ngeemela, ngemilomo yemilomo, iivalvu, iirula, kunye neetheyibhile.
SUS430Umgangatho wokwanda kwe-thermal ephantsi, ukubumba okuhle kunye nokumelana ne-oxidation. Zilungele izixhobo ezinganyangekiyo bubushushu, izitovu, izixhobo zasekhaya, izinto zetheyibhile zeklasi 2, izitya zekhitshi. Ixabiso eliphantsi, ukusebenza kakuhle endaweni efanelekileyo yeSUS304; nokumelana elungileyo, unyango non-ubushushu eqhelekileyo lukhuni intsimbi ferritic stainless.

Umgaqo webhola engenasici:
Amaso e-stainless steel awubonakalisi umhlwa, kodwa akukho lula ukurusa. Umgaqo-siseko kukuba ngokudibanisa i-chromium, umaleko oxineneyo we-chromium oxide wenziwa kumphezulu wesinyithi, onokuthi uthintele ngokufanelekileyo unxibelelwano kwakhona phakathi kwesinyithi kunye nomoya, ukuze ioksijini esemoyeni ingangeni kwisinyithi. ibhola, ngaloo ndlela kuthintelwa Iziphumo intsimbi amaso irusi.
Imigangatho yeSizwe yase-China (i-CNS), iMigangatho yoShishino yaseJapan (i-JIS) kunye ne-American Iron and Steel Institute (i-AISI) zisebenzisa amanani amathathu ukubonisa ii-steels ezahlukeneyo ezingenazintsimbi, ezicatshulwe ngokubanzi kolu shishino, apho uthotho lwama-200 luyi-chromium-nickel-manganese -based austenitic Yenziwe ngentsimbi eshayinayo, 300 uthotho chromium-nickel austenitic insimbi, 400 series chromium insimbi (eyaziwa ngokuba intsimbi), kubandakanya martensite kunye ferrite.
