430 kila kila a i ʻole 201 kila kila ʻoi aku ka maikaʻi?

430 ka ʻili kila kila, ka wela wela, ka ʻakika, ke kinoea alkaline, ka hoʻonā a me ka pale ʻana i ka corrosion media.ʻO ka plasticity kiʻekiʻe, ka paʻakikī a me ka ikaika mechanical;201 ʻO ka paipu kila kila i nā hiʻohiʻona o ka pale ʻana i ka waika, ke kūpaʻa alkali, ke kiʻekiʻe kiʻekiʻe me ka ʻole o nā pinholes, a me nā mea ʻē aʻe, ʻo ia ka hana ʻana i nā hihia wati like ʻole, ke kaula i lalo o ka uhi a me nā mea kiʻekiʻe kiʻekiʻe.201 Hiki ke hoʻohana ʻia nā paipu kila kila i nā paipu hoʻonani, nā paipu ʻoihana, a me nā huahana huki pāpaʻu.

430 kuhiliʻole kila he martensitic kuhiliʻole kila, martensitic kuhiliʻole kila a me ka maʻamau 'ano kila i nā 'ano like o ka paakiki ma o quenching, martensitic chromium kuhiliʻole kila ma quenching - tempering kūlana, hoʻonui i ka maʻiʻo o ka chromium hiki ke hoʻonui i ka ferritic maʻiʻo, pela e hoemi i ka paakiki a me ikaika tensile.Ma lalo o nā kūlana annealing, piʻi ka paʻakikī o ka haʻahaʻa carbon martensitic chromium stainless steel me ka piʻi ʻana o ka chromium content, ʻoiai e emi iki ka elongation.Ma lalo o ke kūlana o kekahi maʻi chromium, e hoʻonui ka hoʻonui ʻana o ke kalapona i ka paʻakikī o ke kila ma hope o ke kinai ʻana, a e emi iho ka plasticity.

Ma hope o ka hoʻopau ʻana i ka wela haʻahaʻa, maopopo loa ka hopena o ka molybdenum.ʻO ke kumu nui o ka hoʻohui ʻana i ka molybdenum e hoʻomaikaʻi i ka ikaika, ka paʻakikī a me ka hopena paʻakikī lua o ke kila.I loko o ka martensitic chromium-nickel stainless steel, hiki ke hoʻemi ʻia ka ʻike o ka δ ferrite i ke kila e kekahi nui o ka nickel, i hiki i ke kila ke loaʻa ka waiwai paʻakikī.

210 kuhiliʻole kila he chromium-nickel austenitic kuhiliʻole kila, austenitic kuhiliʻole kila he non-magnetic a he kiʻekiʻe toughness a me ka plasticity, akā, ka ikaika mea haʻahaʻa, ia mea hiki ole ke hooikaika ma ka māhele hoʻololi, wale ma ka anu hana e hooikaika.Inā hoʻohui ʻia ʻo S, Ca, Se, Te a me nā mea ʻē aʻe, loaʻa iā ia ka machinability maikaʻi.Inā loaʻa iā Mo, Cu a me nā mea ʻē aʻe, hiki iā ia ke pale aku i ka corrosion o sulfuric acid, phosphoric acid, formic acid, acetic acid, urea a pēlā aku.Inā ʻoi aku ka liʻiliʻi o ke kalapona o ia kila ma mua o 0.03% a i ʻole he Ti, Ni, hiki iā ia ke hoʻomaikaʻi maikaʻi i kona kūpaʻa intergranular corrosion.Kiʻekiʻe kiʻekiʻe austenitic kuhiliʻole kila concentrated nitric acid he maikaʻi corrosion kū'ē.No ka mea, he ʻano piha a maikaʻi nā ʻano mea hoʻonaninani austenitic, ua hoʻohana nui ʻia ma nā ʻano āpau o ke ola.
