304 vs 316 kila kila

ʻO 304 a me 316 mau kila kila ʻelua austenitic stainless grades, akā ʻaʻole hiki ke hoʻololi ʻia i ka wā e lilo ai ka ʻoihana lawelawe. ʻO ka ʻokoʻa ʻenehana koʻikoʻi ka haku mele: ʻo ka 304 maʻamau he chromium-nickel stainless steel, aʻo 316 e hoʻohui i ka 2-3% molybdenum a lawe pinepine i kahi pae nickel kiʻekiʻe. ʻO kēlā hoʻohui molybdenum ke kumu nui e hāʻawi ai ʻo 316 i ke kūpaʻa ʻoi aku ka maikaʻi o ka lua a me ka ʻāʻī ʻana i loko o ka chloride{10}}kaiapuni e like me ka ea kahakai, ka paʻakai paʻakai, ka holoi kemika, a me kekahi mau lawelawe hana. ʻO ka ʻokoʻa, ʻo 304 ka papa kumu maʻamau maʻamau -no nā lako o loko, ka hana o ka lewa mālie, a me nā ʻāpana i hana ʻia kahi i kaupalena ʻia ai ka ʻike chloride.

ʻO ka ʻokoʻa ma waena o 304 a me 316 stainless steel no laila ʻaʻole ia he nīnau no ka ikaika a i ʻole ka helehelena. Ma ke kūlana annealed maʻamau, kokoke ko lākou pae mechanical kumu, a ua hoʻohana nui ʻia nā mea ʻelua no ka pepa, ka pā, ka paipu, nā mea pono, nā pahu, a me nā mea hana. ʻO ka hoʻokaʻawale maoli ʻana he corrosion margin. Inā maloʻo ka lawelawe, maʻemaʻe, a ʻaʻole-ʻino, lawa pinepine ka 304.

Mai kahi ʻenehana ʻenehana, ʻo ia ke kumu e hoʻohālikelike pinepine ʻia ai ka 304 a me 316 stainless steel i nā papahana like. Hiki iā lāua ʻelua ke hoʻomāʻona i nā ala hana like ʻole, ʻaʻole naʻe lākou e pane like i ka ʻoihana lawelawe like.

ʻO 304 a me 316 Kūleʻa Kūleʻa ka maʻalahi o ka ʻāpana kemika. Kūkulu ʻia ka 304 maʻamau a puni ka chromium a me ka nickel. Hoʻohana ʻo Standard 316 i kahi waihona like, akā hoʻohui i ka molybdenum a lawe maʻamau i kahi pae nickel kiʻekiʻe. ʻO ia ke kumu nui e koho pinepine ʻia ai ka 316 i ka wā e lilo ai ke kūpaʻa chloride i mea nui.
