Hāʻawi ka hale hana i ka pā kila kuhili ʻole/pepa
200 moʻo—chromium-nickel-manganese austenitic kila kila
300 moʻo—chromium-nickel austenitic stainless steel
301—Maikaʻi ductility, hoʻohana ʻia no nā huahana i hoʻoheheʻe ʻia.Hiki ke hoʻopaʻakikī koke ʻia e ka mīkini.Maikaʻi weldability.ʻOi aku ka maikaʻi o ka pale abrasion a me ka ikaika luhi ma mua o 304 stainless steel.
302—Ua like ka pale ʻana i ka corrosion me ka 304, a ʻoi aku ka maikaʻi o ka ikaika ma muli o ke kiʻekiʻe o ke kalapona.
303—Ma hope o ka hoʻohui ʻana i kahi liʻiliʻi o ka sulfur a me ka phosphorus, ʻoi aku ka maʻalahi o ka ʻoki ʻana ma mua o 304.
304—ʻo ia hoʻi, 18/8 kila kila.ʻO ka hōʻailona GB ʻo 0Cr18Ni9.
309—Hoʻohālikelike ʻia me 304, ʻoi aku ka maikaʻi o ka pale ʻana i ka wela.
316—Ma hope o 304, ʻo ka lua i hoʻohana nui ʻia i ke kila kila, i hoʻohana nui ʻia i ka ʻoihana meaʻai a me nā mea hana ʻokiʻoki, e hoʻohui ana i ka molybdenum element e loaʻa ai kahi hale kūʻokoʻa corrosion.No ka mea ʻoi aku ka maikaʻi o ke kūʻē ʻana i ka chloride corrosion ma mua o 304, hoʻohana ʻia ʻo ia ma ke ʻano he "moku kila".Hoʻohana pinepine ʻia ʻo SS316 i nā mea hoʻolaʻa wahie nuklea.18/10 pae kila kuhiliʻole maʻamau pū me kēia pae noi.
321—Koe wale no ka hoʻohui ʻana o ka titanium, e hōʻemi ana i ka pilikia o ka weld corrosion data, ua like nā hana ʻē aʻe me 304.
400 moʻo—ferritic a martensitic kila kila
408—Maikaʻi ka wela, nāwaliwali nāwaliwali, 11% Cr, 8% Ni.
409—ʻo ke ʻano haʻahaʻa loa (Beretania a me ʻAmelika), i hoʻohana maʻamau ʻia ma ke ʻano he paipu hoʻopau kaʻa, he kila kila ferritic (he kila chrome).
410—Martensite (he kila chromium ikaika kiʻekiʻe), maikaʻi ke pale ʻana i ka ʻaʻahu, maikaʻi ʻole ke kū ʻana i ka corrosion.
416—Hoʻohui i ka sulfur a hoʻomaikaʻi i ka hana hana o ka ʻikepili.
420—"mea paahana" kila martensitic, e like me ke kila kuhiliʻole mua loa e like me Brinell kila chromium kiʻekiʻe.Hoʻohana ʻia ia no nā pahi ʻokiʻoki, hiki ke mālamalama loa.
430—He kila kila Ferritic, no ka hoonani, e like me na lako kaa.ʻOi aku ka maikaʻi o ka formability, akā maikaʻi ʻole ka pale wela a me ke kūpaʻa corrosion.
440—Ke kila ʻoki ikaika kiʻekiʻe me ka maʻi kalapona kiʻekiʻe iki.Ma hope o ka mālama ʻana i ka wela kūpono, hiki ke loaʻa ka ikaika hua kiʻekiʻe.Hiki i ka paʻakikī ke hiki i 58HRC, ka mea i hoʻokaʻawale ʻia ʻo ke kila kila paʻakikī.ʻO ka laʻana maʻamau ʻo "nā pahi pahi."ʻEkolu mau ʻano maʻamau: 440A, 440B, 440C, a me 440F (ʻano hana maʻalahi) no nā poʻe ʻē aʻe.
500 moʻo—he kila chromium pale wela.
600 moʻo—Martensite accumulation paakiki kila kuhiliʻole.
630—ʻO ke ʻano mea maʻamau o ka hoʻopaʻa paʻa ʻana i ke kila kila, i kapa ʻia ʻo 17-4;17% Cr, 4%.Ni.
