7. 317 kila kila. ʻOi aku ka maikaʻi o ka pitting corrosion resistance a me ka creep resistance ma mua o ka 316L stainless steel, i hoʻohana ʻia i ka hana ʻana i nā mea hoʻoheheʻe petrochemical a me nā mea hoʻonaninani.

8. 321 kila kila. Titanium-stabilized austenitic stainless steel, hoʻohui i ka titanium e hoʻomaikaʻi i ka intergranular corrosion kū'ē, a loaʻa ka maikaʻi kiʻekiʻe-mehana mechanical waiwai, hiki ke pani ʻia e ka ultra-low carbon austenitic stainless steel. Ma waho aʻe o nā hanana kūikawā e like me ke kiʻekiʻe kiʻekiʻe a i ʻole hydrogen corrosion resistance, ʻaʻole ʻōlelo ʻia no ka hoʻohana.

9. 347 kila kila. ʻO Niobium-stabilized austenitic stainless steel, hoʻohui i ka niobium e hoʻomaikaʻi i ke kūpaʻa intergranular corrosion, ke kūpaʻa ʻana o ka corrosion i loko o ka waikawa, alkali, paʻakai a me nā mea ʻē aʻe corrosive like me 321 stainless steel, maikaʻi kuʻi ʻana hana, hiki ke hoʻohana ʻia e like me ka corrosion-resistant material and anti -corrosion Hoʻohana nui ʻia ke kila wela i ka mana wela a me nā māla petrochemical, e like me ka hana ʻana i nā ipu, nā paipu, nā mea hoʻololi wela, nā shafts, nā paipu umu. i loko o nā kapuahi ʻenehana, a me nā mea wela wela o ka umu.

10. 904L kila kila. ʻO ke kila kila austenitic piha piha he ʻano kila kila ʻoi loa i hana ʻia e OUTOKUMPU ma Finland. , Loaʻa iā ia ke kūpaʻa corrosion maikaʻi i nā waikawa non-oxidizing e like me ka sulfuric acid, acetic acid, formic acid a me ka phosphoric acid, a he kūʻē maikaʻi hoʻi i ka crevice corrosion a me ke koʻikoʻi corrosion kū'ē. He kūpono ia no nā ʻano like ʻole o ka sulfuric acid ma lalo o 70 ° C, a he kūpaʻa maikaʻi ka corrosion i ka acetic acid a me ka hui ʻana o ka waikawa formic a me ka acetic acid i kēlā me kēia ʻano a me ka mahana ma lalo o ke kaomi maʻamau. ʻO ka maʻamau maʻamau ASMESB-625 e hoʻokaʻawale iā ia ma ke ʻano he nickel-based alloys, a ʻo ka maʻamau hou e hoʻokaʻawale iā ia me ke kila kila. He mau helu like wale nō o 015Cr19Ni26Mo5Cu2 kila ma Kina. Hoʻohana kekahi mau mea hana ʻEulopa i ka 904L stainless steel ma ke ʻano he mea nui. No ka la'ana, hana 'ia ka paipu ana o E+H me ke kila kuhili'ole 904L, a 'o ka hihia o nā wati Rolex i hana 'ia me 904L kila kila.

11. 440C kila kila. ʻO ke kila kila Martensitic ka paʻakikī kiʻekiʻe loa ma waena o nā kila kila a me nā kila kila, me ka paʻakikī o HRC57. Hoʻohana nui ʻia e hana i nā nozzles, bearings, valve cores, valve seats, sleeves, valve stems, etc.

12. 17-4PH kila kuhiliʻole. Martensitic precipitation hardening stainless steel me ka paʻakikī o HRC44 he kiʻekiʻe ka ikaika, paʻakikī a me ka corrosion a ʻaʻole hiki ke hoʻohana ʻia i nā mahana ma luna o 300°C. Loaʻa iā ia ka pale corrosion maikaʻi i ka lewa a me ka waikawa diluted a i ʻole ka paʻakai. ʻO kona kūpaʻa corrosion e like me ka 304 stainless steel a me 430 stainless steel. Hoʻohana ʻia ia no ka hana ʻana i nā paepae o waho, nā lau turbine, nā cores valve, nā noho kiwi, nā lima lima, nā ʻōpala valve E kali.
