ʻOkoʻa ma waena o SUS 304,430,420,410

Ke kila kila e pili ana i ka corrosion kū'ē o ka ea, mahu, wai a me nawaliwali corrosive medium, a me ka waika, alkali, paʻakai a me kekahi kemika etched medium corrosion o ke kila, i ikeia hoi he kuhiliʻoleʻakika pale kila. e like me ke kūkulu hale, nā lako pākaukau, nā mea hana hale, nā ʻoihana, a me nā mea ʻē aʻe. E like me ke ʻano o ka metallurgical, ua ʻike ʻia ke kila kila i ʻekolu mau ʻano, e komo pū ana me ke kila kuhili ʻole, ferric stainless steel a me martensite stainless steel. kila i mea e hoʻokō ai i nā pono a me nā koi ʻē aʻe. Aia-i loko, ʻo SUS 340 ka mea i hoʻopaʻa ʻia i ke kila kila kila, SUS 430 pili i ka ferric stainless steel a me SUS 410,420 hele me ka martensite stainless steel. Eia kekahi ʻokoʻa ma waena o lākou.
1.430 vs 304
ʻO ka mea mua, hiki i ka chrome content o SUS 430 i ka 16% -18% a ʻaʻohe kumu nickel. A loaʻa iā SUS 304 nā mea ʻelua. ʻoi aku ka kiʻekiʻe o SUS 304 ma mua o SUS 430.

ʻO ka mea hou aku, hoʻohana nui ʻia ʻo SUS 430 ma ka ʻāina o ka hoʻonani hale, nā mea hana hale, ka mea puhi ahi. ʻO ka puni ʻino, e like me ke kahakai, kahi anu a me ka pulu. Ua makemake nui ʻo SUS 430 i ka hoʻohana ʻana i ke ʻano wela wela, e like me ka paila, ka wai wela, ka ʻōnaehana hoʻolako wela, etc.

1.410 vs 420 vs 430
410 - ka paʻakikī a me ke kūpaʻa abrasion maikaʻi

420 — Prop grade” kila martensite, e like me ke kila chromium kiʻekiʻe brilliantine, ke kila kuhili ʻole mua loa, ua hoʻohana ʻia i nā pahi ʻokiʻoki a hiki ke hana ʻia.
430 - ma ke ʻano he kumu hoʻonaninani, loaʻa ke ʻano maikaʻi loa, akā ʻoi aku ka maikaʻi o ka mahana a me ka pale ʻana i ka corrosion

ʻEkolu mau kumu kumu e pili ana i ke kumu o ka ʻōpala kila kuhiliʻole.

ʻO ka maʻiʻo o ka mea hoʻohuihui
ʻO ka mea maʻamau, paʻakikī ka ʻōpala inā kokoke ka ʻike o ka chromium i ka 10.5%. ʻO ia hoʻi, ʻoi aku ka kiʻekiʻe o ka maʻiʻo o ka chromium, ʻoi aku ka maikaʻi o ke kūpaʻa corrosion. % a me ka ʻike o ka corrosion e hoʻokokoke ana i ka 18% -20%, ʻaʻole e rust ka SUS 304.
Kaʻina hoʻoheheʻe o ka ʻoihana hana
Ma muli o ka ʻenehana hoʻoheheʻe maikaʻi, nā mea hana kiʻekiʻe, ka mana o ka alloy element a me ka billet cooling temperature a me ka wehe ʻana i nā mea haumia hiki ke hōʻoia maikaʻi ʻia e ka hale hana kila stainless nui.
Kaiapuni palekana
ʻO ke kaiapuni me kahi ea maloʻo a me ke kūlana ventilated he paʻakikī ke rust. A ʻo ka wahi me ka nui o ka ea ea, ka ua nui, ka pH nui i ka lewa he maʻalahi ka pala.
E like me ke kumu like ʻole, loaʻa i kēlā me kēia kila kila kona hemahema a me ka lōʻihi, e pili ana i nā ʻoihana like ʻole.
