17-4 PH vs 316 Stainless Steel – He aha ka ʻokoʻa?

E like me ka mea akamai i ka hana o ka metallurgy mai Kinohi Pilikino Sino, Ua hoʻohana au i nā makahiki i ke aʻo ʻana a me ka hana ʻana me nā ʻano huila like ʻole. Ma waena o ka nui o nā mea aʻu i hālāwai ai, 17-4 PH vs 316'ōpana kila kū ʻo ia ma ke ʻano he ʻelua huila kaulana. Loaʻa iā lāua nā hiʻohiʻona kūʻokoʻa a me nā noi, akā ʻo ia nā ʻokoʻa maʻalahi a koʻikoʻi ma waena 17-4 PH & 316 kila kila e hana i kēlā me kēia huila kūpono no nā hoʻohana kikoʻī.

17-4 PH vs 316 Stainless Steel – He aha ka ʻokoʻa?

E hoʻomaka kākou me kahi ʻike pōkole o 17-4 PH kila kila. ʻO kēia huila, i ʻike ʻia ʻo UNS S17400, no ka papa o nā kila kila martensitic paʻakikī paʻakikī. Loaʻa kona inoa mai ka haku mele ʻana o chromium (17%) a nikala (4%), ka mea i hāʻawi nui i kona pale ʻana i ka corrosion a me nā waiwai mechanical. ʻO ke kaʻina hana paʻakikī o ka ua e pili ana i ka hoʻokumu ʻana i nā ʻāpana maikaʻi i loko o ka matrix kila, e hoʻonui ai i kona ikaika a paʻakikī. Hana kēia i ka 17-4 PH i koho maikaʻi loa no nā noi e koi ana i ka ikaika kiʻekiʻe a me ke kūpaʻa corrosion maikaʻi, e like me nā ʻāpana aerospace, nā mea hana kemika, a me nā implants olakino.

Ma ka ʻaoʻao ʻē aʻe, ʻo 316 stainless steel he austenitic stainless steel i loaʻa i ka molybdenum, me ka chromium a me ka nickel. ʻO ka hoʻohui ʻana i ka molybdenum e hoʻomaikaʻi maikaʻi i ka pale ʻana i ka ʻino o ka alloy, ʻoi aku ka nui o nā ion chloride, i kūpono ia no ka hoʻohana ʻana i nā kaiapuni moana a me nā kūlana ʻino ʻē aʻe. Hoʻohana nui ʻia ʻo 316 stainless steel i ke kūkulu ʻana i nā mea kanu kemika, nā mea hana meaʻai, a me nā mea ʻokiʻoki ma muli o kona kūpaʻa maikaʻi ʻana i ka corrosion a me ke ʻano maikaʻi.

I kēia manawa, e noʻonoʻo kākou i nā ʻokoʻa koʻikoʻi ma waena o kēia mau alloy ʻelua.

17-4 PH vs 316 Kuhili ʻole – Nā Pono Mechanical

ʻO ka ʻokoʻa mua loa e pili ana i kā lākou mau waiwai mechanical. ʻO 17-4 PH, ma o kāna kaʻina hana paʻakikī, loaʻa ka ikaika kiʻekiʻe a me ka paʻakikī i hoʻohālikelike ʻia me 316 stainless steel. ʻO kēia ke koho kūpono no nā noi kahi mea koʻikoʻi ka ikaika kiʻekiʻe a me ka pale ʻana. Eia nō naʻe, pono e hoʻomaopopo i ka hana martensitic o 17-4 PH hiki ke hoʻohaʻahaʻa i ka ductile a ʻoi aku ka paʻakikī o ka hana ʻana ma mua o nā kila stainless austenitic e like me 316.

17-4 PH vs

Ma ke alo o ka pale ʻana i ka corrosion, hāʻawi nā ʻelua ʻelua i ka hana maikaʻi loa, akā ʻo ka 316 stainless steel ka lihi. ʻO ka hoʻohui ʻana o ka molybdenum i ka 316 stainless steel e hoʻonui i kona kūpaʻa ʻana i ka corrosion, ʻoi aku hoʻi i nā wahi waiwai chloride. Hoʻolilo kēia i ka 316 stainless steel i koho maikaʻi ʻia no nā noi kai a me nā hoʻonohonoho ʻē aʻe kahi e ʻike ʻia ai i ka wai paʻakai a i ʻole ka chloride.

17-4 PH vs 316 Kuhili ʻole – Weldability

ʻO ka Weldability kekahi mea nui e noʻonoʻo ai. ʻO 316 kila kila, ma muli o kona ʻano austenitic, ʻoi aku ka maʻalahi o ka weld ma mua o 17-4 PH. He maikaʻi ka ductility a me ka formability Austenitic stainless steels, e hoʻomaʻamaʻa i nā kaʻina hana wili. Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka paʻakikī o ka welding 17-4 PH ma muli o kona ʻano martensitic a me ka hiki ke haki a me ka distortion. Pono pinepine ʻia nā ʻenehana kuʻi ʻana a me ka mālama ʻana i ka wela ma hope o ka weld e hōʻoia i ka pono o nā hui welded ma 17-4 PH.

17-4 PH vs 316 kila kila – ke kumu kūʻai

ʻO ke kumukūʻai kekahi mea pono e noʻonoʻo ʻia. Ma keʻano laulā, ʻoi aku ka nui o ke kila kila 316 a ʻoi aku ka nui o ke kumukūʻai ma mua o 17-4 PH. ʻO kēia no ka mea ʻoi aku ka maʻalahi o ke kila kila 316 a hoʻohana pinepine ʻia i nā ʻoihana like ʻole. Eia nō naʻe, ʻokoʻa ke kumukūʻai ma muli o nā kūlana mākeke a me nā koi kikoʻī o ka noi.

17-4 PH vs 316 Kuhili ʻole - Nā noi

Ma keʻano o nā noi, loaʻa pinepine ka 17-4 PH stainless steel i nā noi hana kiʻekiʻe kahi i koʻikoʻi ai ka ikaika a me ka pale ʻana i ka corrosion. Hoʻopili kēia i nā ʻāpana aerospace, nā mea ʻimi ʻaila a me ke kinoea, a me nā mea hoʻopaʻa e pono ai ka lōʻihi. Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka maʻamau o ka 316 stainless steel i nā noi e pili ana i ka hoʻolaha ʻana i nā kaiapuni corrosive, e like me ke kūkulu ʻana i ke kai, ka hana kemika, a me ka hana meaʻai.

Panina

I ka hopena, ʻo 17-4 PH a me 316 stainless steel ʻelua mau ʻāpana ʻokoʻa me kā lākou mau pono ponoʻī a me nā noi. Hāʻawi ʻo 17-4 PH i ka ikaika a me ka paʻakikī ma o ka hoʻopaʻa ʻana i ka ua, kūpono ia no nā noi hana kiʻekiʻe. Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka maikaʻi o ka 316 stainless steel i ka pale ʻana i ka corrosion, ʻoi aku ka kūʻē ʻana i nā ion chloride, a hoʻohana nui ʻia i nā kaiapuni kai a me nā kemika.

Mahalo iā ʻoe no ka heluhelu ʻana i kā mākou ʻatikala a ke manaʻo nei mākou e hiki ke kōkua iā ʻoe e ʻike maikaʻi i nā ʻokoʻa ma waena o 17-4 PH vs 316 Stainless Steel. Inā ʻoe e ʻimi nei i nā mea kūʻai aku 316 Stainless Steel a me nā mea hana ma ka pūnaewele i kēia manawa, e aʻo mākou iā ʻoe e kipa Kinohi Pilikino Sino.

Ma ke ʻano he alakaʻi alakaʻi o nā huahana kila kila mai Shanghai Kina, hāʻawi ʻo Sino Stainless Steel i nā mea kūʻai aku kiʻekiʻe 316 Stainless Steel, nā lau hoʻohiwahiwa kila, paipu kila kila, paipu kila kila, nā ʻili kila kuhili ʻole, nā wili kila kila, nā pā kila kila, a nā pahu kila kila ma ke kumu kūʻai hoʻokūkū loa.
