I kēia manawa ma ka mākeke kūʻai Kina okila kohu ʻoleʻO ka nui o ka 300 series a me ka 200 series, ʻo ka ʻokoʻa ma waena o nā mea ʻelua ʻo ia ka nui o nā mea nickel element kemika, kahi i hana ai lākou i ka hana a me ke kumukūʻai o ka ʻokoʻa nui.
Ma ka pae o kēia manawa o nā kumukūʻai nickel, haʻahaʻa loa ka maʻiʻo nickel 200 series stainless steel kumu kūʻai ma kahi o ka hapalua o ka 300 series stainless steel, corrosion a me ka paʻakikī i ka hana puna ʻoi aku ka hewa ma mua o ka 300 serieskila kohu ʻole, pili wale i ka hana ʻai meaʻai a me nā māla ʻē aʻe, inā hoʻohana ʻia i ke kūkulu ʻana, nā mea lapaʻau, ke kahua o ka hīnaʻi, e nui ka pilikia huna.ʻO ka maʻiʻo nikela ma kahi o 1% o nā huahana 200 series, ʻaʻole hiki ke hoʻopili ʻia i ka corrosion maʻamau.
300 moʻo kila kilaʻike ʻia hoʻi ʻo 18-8 kila, ʻo ia nā mea hoʻopaʻa, nā hono, nā paipu a me nā paipu i hoʻohana pinepine ʻia.18-8 kila ka nominal maʻiʻo o ka chromium a me ka nickel i 300 moʻo kuhiliʻole kila, keia mau mea ma luna o ka ili o ka maikaʻi corrosion kū'ē, akā, ma muli o ka deposition o kalapona, e hana i ka chromium maʻiʻo emi.Hoʻohui ʻia ʻo Chromium me ke kalapona i nā wela kiʻekiʻe e hana i ka chromium carbide, ʻaʻole ia e pale i ka pala.
400 moʻo kuhiliʻole kila chromium maʻiʻo ma mua o300 moʻo kila kilahaʻahaʻa, akā, ʻaʻole like me 300 moʻo i carbon deposition pilikia, a hiki ke wela-hana, akā, ma muli o ka chromium maʻiʻo o wale 12% o 14%, i loko o ke kaiapuni o ke koʻikoʻi kemika lewa e corrode ka hoʻohana 'ana o 300 moʻo i loaʻa 16 % o 20% o ka chromium, ʻaʻole ia e ʻino.300 series stainless steel a me 400 series stainless steel i ka ikaika like.
