ʻO ka hoʻohālikelike hana o 304L a me 316L i kāhili ʻia i ka pā kila kila

ʻO 304 a me 316 nā code ʻelua o ke kila kila.ʻO ke kumu, ʻaʻole lākou he ʻokoʻa.He kila kila ʻelua lākou, akā no nā ʻano like ʻole ke māhele ʻia.ʻOi aku ka maikaʻi o ka 316 stainless steel ma mua o ka 304 stainless steel.Ma ke kumu o 304,316 kila kilahoʻokomo i ka molybdenum metala, hiki ke hoʻohui hou i ke ʻano mole o ke kila kila.E hoʻonui i ka pale a me ka anti-oxidation, a i ka manawa like, ua hoʻonui nui ʻia ke kūpaʻa corrosion.
Hoʻohālikelike hana o 304L a316L i kāhili ʻia i ka pā kila kila
ʻOi aku ka maikaʻi o ke kūpaʻa ʻino o ke kila kila ma mua o kona kūʻē ponoʻī.Ma ke ʻano he alloy, ʻo ka hui mua o ke kila kila he hao, akā ma muli o ka hoʻohui ʻana o nā mea ʻē aʻe, hiki iā ia ke hoʻokō i nā waiwai noi i makemake ʻia.ʻO Chromium ka mea hoʻoholo i ke kila kila, ma kahi o 10.5% o ka haku mele.ʻO nā mea hoʻohui ʻē aʻe he nickel, titanium, keleawe, nitrogen a me selenium.
ʻO ka ʻokoʻa ma waena o 304L a me 316L brushed Stainless Steel Plate ʻo ka hele ʻana o ka chromium, 316L brushed stainless steel i ʻoi aku ka maikaʻi o ka corrosion, ʻoi aku ka maikaʻi ma ke kaiapuni waena me ka salinity kiʻekiʻe.No nā noi me nā huahana kila kila waho, ʻo ke kila kila he mea kūpono i ka corrosion-resistant no ka lōʻihi o ka hoʻolaha ʻana i waho.
kūpaʻa ʻino maoli
Hiki i nā mea like ʻole o ka chromium a me nā mea ʻē aʻe ke hōʻike i nā pae like ʻole o ka pale ʻana i ka corrosion.ʻO nā papa kila kuhiliʻole maʻamau ʻelua ʻo 304 a me 316. ʻO ka corrosion kahi mea kūlohelohe, e like me ka hana ʻana o ka hao me kona puni.ʻO kaʻoiaʻiʻo, hiki ke loaʻa nā mea liʻiliʻi ma ke ʻano maʻemaʻe - he mau hiʻohiʻona liʻiliʻi loa ke gula, ke kālā, ke keleawe, a me ka platinum.
Hoʻokumu ʻo Chromium oxide i kahi kiʻiʻoniʻoni pale i kūkulu ʻia
ʻO ka Rusting ke kaʻina hana e hui pū ai nā molekala hao me ka oxygen i loko o nā molekele wai, a ʻo ka hopena he ʻulaʻula ʻulaʻula e ʻoi aʻe ka ʻino - e ʻānai ana i nā mea.ʻO kēia mau mea, ʻoi aku ka maʻalahi o ka hao a me ke kila kalapona i kēia corrosion.
Hiki i ke kila kila ke hoʻopōʻino i ka ʻili, pehea e hiki mai ai kēia?ʻO ka Chromium i loko o nā kila kila a pau e hana wikiwiki loa i ka oxygen, e like me ka hao.ʻO ka ʻokoʻa, ʻo kahi ʻāpana lahilahi o ka chromium e hoʻoheheʻe ʻia (ʻo ka maʻamau he mole liʻiliʻi wale nō i ka mānoanoa).ʻO ka mea kupaianaha, he lōʻihi loa kēia ʻāpana lahilahi o ka pale.
304L brushed stainless steel he hiʻohiʻona nani a me ka uku mālama haʻahaʻa.ʻAʻole maʻalahi ka 304L brushed stainless steel, no laila hoʻohana pinepine ʻia i nā mea kuke a me nā noi meaʻai.Akā hiki ke maʻalahi i nā chlorides (maʻamau i nā wahi paʻakai kiʻekiʻe).Hoʻokumu ʻo Chloride i kahi ʻano o ka pōʻino i kapa ʻia ʻo "kahi corrosion" e hoʻonui i ka hale i loko.
ʻO 304 ke kila kila ka mea i hoʻohana nui ʻia ma ka honua.Loaʻa iā 16% -24% chromium a hiki i ka 35% nickel - a me nā pae haʻahaʻa o ke kalapona a me ka manganese.ʻO ke ʻano maʻamau o 304 stainless steel he 18-8, a i ʻole 18/8 stainless steel, e pili ana i ka 18% chromium a me 8% nickel.
ʻO 316 ke kila kila he kila kila nui hoʻi ia.ʻO kona mau kino kino a me ka mechanical e like me ka 304 stainless steel.ʻO ka ʻokoʻa, ʻo 316 stainless steel ka 2-3% molybdenum, e hoʻonui ai i ka ikaika a me ka pale ʻana i ka corrosion.ʻO ka maʻamau 300 series stainless steels hiki ke loaʻa i ka 7% aluminika.
304L a me 316Lnā kila kuhili ʻole(e like me nā 300 series stainless steels) hoʻohana i ka nickel no ka mālama ʻana i kā lākou mau mea hoʻonaninani haʻahaʻa.
