KA OKE MA waena o 304 a me 316 STANLES STEEL

I ke koho ʻana i kahikila kohu ʻolepono e hoʻomanawanui i nā kaiapuni corrosive,austenitic stainless steelshoʻohana maʻamau. ʻO ka loaʻa ʻana o nā waiwai mechanical maikaʻi loa, ʻo ka nui o ka nickel a me ka chromium i loko o nā kila stainless austenitic e hāʻawi pū i ka pale ʻana i ka corrosion. Eia hou, nui nā austenitic stainless steels i weldable a formable. ʻElua o nā māka maʻamau i hoʻohana pinepine ʻia o ka austenitic stainless steel he mau māka304a316. No ke kōkua ʻana iā ʻoe e hoʻoholo i ka papa kūpono no kāu papahana, e nānā kēia blog i ka ʻokoʻa ma waena o 304 a me 316 kila kila.

304 Ke kila kila

Manaʻo ʻia ke kila kuhili ʻole papa 304 ma ke ʻano he kila kila austenitic maʻamau. Loaʻa iā ia ka maʻiʻo nickel kiʻekiʻe ma waena o 8 a 10.5 pākēneka o ke kaumaha a me ka nui o ka chromium ma kahi o 18 a 20 pakeneka ma ke kaumaha. ʻO nā mea hoʻohui nui ʻē aʻe e pili ana i ka manganese, silika, a me ke kalapona. ʻO ke koena o ka hui kemika he hao.

Hāʻawi ka nui kiʻekiʻe o ka chromium a me ka nickel i ka 304 stainless steel maikaʻi loa i ka corrosion resistance. ʻO nā mea hoʻohana maʻamau o 304 stainless steel me:

• ʻO nā mea hana e like me nā pahu hau a me nā mea holoi ipu
• Nā lako hana meaʻai kālepa
• Nā mea paʻa
• Paipu
• Nā mea hoʻololi wela
• Nā hale i loko o nā kaiapuni e ʻino ai ke kila kalapona maʻamau.

316 Ke kila kila

E like me 304, ʻo Grade 316 stainless steel ka nui o ka chromium a me ka nickel. Aia i loko o 316 ke silikoni, manganese, a me ke kalapona, me ka hapa nui o ka haku mele he hao. ʻO kahi ʻokoʻa nui ma waena o 304 a me 316 ke kila kila ʻo ia ka haku melemele, me ka 316 i loaʻa ka nui o ka molybdenum; ʻO ka maʻamau 2 a 3 pākēneka ma ke paona vs nā ʻāpana ʻili wale nō i loaʻa i ka 304. ʻO ka ʻike molybdenum kiʻekiʻe ka hopena i ka papa 316 i loaʻa ka piʻi ʻana o ka corrosion.

Manaʻo pinepine ʻia ʻo 316 stainless steel kekahi o nā koho kūpono loa i ke koho ʻana i ke kila kila austenitic no nā noi kai. ʻO nā noi maʻamau ʻē aʻe o 316 stainless steel me:

• ʻO ka hana kemika a me nā lako mālama.
• Mea hana hoʻoheheʻe
• Nā mea lapaʻau
• ʻO nā kaiapuni kai, ʻoi aku ka poʻe me nā chlorides

He aha kāu e hoʻohana ai: Papa 304 a i ʻole Papa 316?

Eia kekahi mau kūlana i ʻoi aku ka maikaʻi o ke kila kila 304:

• Pono ka palapala noi i ka formability maikaʻi loa. Hiki ke loaʻa nā hopena maikaʻi ʻole o ka maʻiʻo molybdenum kiʻekiʻe ma ka Papa 316 i ka formability.
• He pilikia ko ka palapala noi. ʻOi aku ka maʻalahi o ka papa 304 ma mua o ka Papa 316.

Eia kekahi mau kūlana i ʻoi aku ka maikaʻi o ka 316 stainless steel.

• ʻO ke kaiapuni ka nui o nā mea corrosive.
• E waiho ʻia ka mea ma lalo o ka wai a i ʻole e ʻike mau ʻia i ka wai.
• I nā noi kahi e koi ʻia ai ka ikaika a me ka paʻakikī.
