ʻO ka pane ʻo ia ka maikaʻi o316 kila kilaʻoi aku ka maikaʻi ma mua o ka304 kila kila, no ka mea, ua hoʻohui ʻia ʻo 316 stainless steel me ka molybdenum metala ma ke kumu o 304, hiki i kēia mea ke hoʻohui hou i ka molecular structure o ke kila kila, e hoʻonui ai i ka lole a me ka anti-oxidation, a i ka manawa like, ʻoi aku ka pale ʻana i ka corrosion. mahuahua loa.E nānā kākou i ke kila kila 304 a me ke kila kila 316 maikaʻi.ʻO nā ʻano kila kuhili ʻole i hoʻohana nui ʻia ʻo 304 a me 316. ʻO ka ʻōnaehana hoʻokele grading i hoʻohana ʻia no ka hoʻokaʻawale ʻana i kēia mau ʻano kila ʻelua mai ka ʻōnaehana ʻike helu helu i hoʻomaka ʻia e ka American Iron and Steel Association of China (AISI), kekahi o nā mea kahiko loa. ʻO nā hoʻoikaika uniona a hiki i kēia lā e hoʻi ana i ka makahiki 1855. Hōʻike kēia mau papa inoa i kā lākou haku mele ʻana, a ʻo ka hapa nui o 200 - a me 300-grade stainless steels i manaʻo ʻia he austenitic.ʻO ke kaʻina hana o ka austenitizing e pili ana i ka hoʻomehana ʻana i ka hao, ferroalloy, a i ʻole ke kila a hiki i kahi e loli ai kona ʻano aniani mai ka ferrite a i ka austenite.ʻOiai he mea paʻakikī ke hoʻokaʻawale i nā mea ʻelua me ka maka ʻōlohelohe, hiki i nā waiwai huahana kūʻokoʻa ma waena o 304 a me 316 mau hui stainless steel hiki ke hoʻonui iā lākou i kekahi mau noi loea.
Mai ka hoʻomohala ʻana o ka hana Kina i ke kenekulia 20, ua lilo nā ʻoihana kila kila i mea koʻikoʻi koʻikoʻi i nā papahana he nui ma Kina no ko lākou lōʻihi, kiʻekiʻe mechanical workability, weldability a me ka maʻalahi.Loaʻa iā ia kekahi mau pākēneka like ʻole o nā mea i kuleana no nā pae like ʻole i ʻike ʻia i kēia manawa.Loaʻa i kēlā me kēia papa kona mau waiwai ponoʻī, a ʻo ka hoʻohālikelike ʻana ma waena o nā papa ʻelua, e like me ka manawa ʻole e like me kā lākou hana ʻana, ʻo 304 a me 316 ke kila kila.
ʻO wai ka maikaʻi, 304 a i ʻole 316 kila kila
Ke nānā ʻoe i nā ʻano kila ʻelua, ua like lāua i ka helehelena a me ka hoʻohui kemika.Hāʻawi nā mea ʻelua i ka pale maikaʻi loa i ka ʻōpala a me ka corrosion, ʻoiai e hāʻawi pū ana i ka lōʻihi.I ka hoʻohālikelike ʻana i ka 304 a me 316 stainless steel, hiki ke hoʻohālikelike ʻia ke kumukūʻai kiʻekiʻe o ka hope i kona kūpaʻa ʻana i ka corrosion.Ma muli o kēia ʻokoʻa kumu kūʻai a me ke kaiapuni liʻiliʻi i kūpono i ke kila 316, ʻo 304 ka kila ka mea i hoʻohana nui ʻia austenitic stainless steel.
ʻOi aku ke kumukūʻai o ke kila kila kila ma ka papa 316 ma muli o kona kūpaʻa ʻana i ka corrosion.No nā noi kahi e hōʻike ʻia ai nā alloys i nā hāʻina chlorinated a me nā chlorides (me ka wai kai Kina), ʻoi aku ka manaʻo e hoʻohana ʻia ka ʻōnaehana ma o kēia huila me nā māka kiʻekiʻe.Hiki ke hoʻohana ʻia e hoʻolōʻihi i ke ola o ka ʻoihana lawelawe o nā ʻāpana a i ʻole nā mea hana i hōʻike mālie ʻia i nā kūlana kaiapuni paʻakikī a corrosive, ʻoi aku hoʻi i nā hihia e pili ana i ka pilikia pilikia i ka paʻakai.Eia naʻe, ʻoi aku ka maikaʻi o ka pae 304 no ka hapa nui o nā noi.I ka hōʻuluʻulu manaʻo, i ka nānā ʻana i nā kila stainless 304 a me 316, no nā noi e koi ana i ka corrosion maikaʻi a i ʻole ke kūpaʻa wai, e hoʻohana i 316 stainless steels.No nā noi ʻē aʻe, ua hana ʻia ʻo 304 stainless steel.ʻO nā mea āpau, ʻo 304 a me 316 nā code o ke kila kila, ʻo ka mea nui, ʻaʻohe ʻokoʻa ma waena o lākou he kila kila, hoʻokaʻawale ʻia lākou i nā ʻano like ʻole.Ma ka waiho wale ʻana, ʻoi aku ka maikaʻi o ka 316 stainless steel ma mua o 304 stainless steel, 316 stainless steel ma ke kumu o 304 i loko o ka molybdenum metala, hiki i kēia mea ke hoʻohui hou i ke ʻano mole o ke kila kila, e hoʻonui i ka pale a me ka oxidation. i ka manawa like, ua hoʻonui nui ʻia ke kūpaʻa corrosion.
