Hoʻohui a me nā waiwai o 409 Kuhili ʻole

409'ōpana kila he kila kila ferritic maʻamau i hoʻohana ʻia i nā mīkini, hana, a me nā noi ʻenehana ʻē aʻe. Ma muli o ka loaʻa ʻana o nā huaʻai austenite, ua hoʻomaikaʻi maikaʻi ʻia kona mau mea mechanical, a ua hoʻonui nui ʻia kona ikaika a me ka paʻakikī ma muli o ka hoʻohui ʻana o nā mea hoʻohui. Ma kēia pou, e nānā pono kākou i ka haku mele a me nā waiwai o 409 stainless steel.

Hoʻohui Kimia o 409 Kuhili ʻole

Hoʻokaʻawale ka hui kemika o 409 stainless steel mai nā ʻano kila kila ʻē aʻe. Ua haku mua ia me ka hao a loaʻa ka nui o ka chromium a me ka liʻiliʻi o carbon, manganese, silicon, a me ka nitrogen.

ʻO ka hao ka mea nui i ka 409 stainless steel, hāʻawi iā ia me ka ikaika a me ka paʻa. Hāʻawi ʻo Chromium i ka pale ʻana i ka ʻino a kōkua i ka hoʻokumu ʻana i kahi ʻāpana oxide pale ma ka ʻili. Kōkua ʻo Carbon i ka hoʻomaikaʻi ʻana i ka paʻakikī o ka mea a me ke kūpaʻa ʻana.

Hiki i ka manganese ke hana ma ke ʻano he stabilizer, pale i ka ulu ʻana o ka palaoa i ka wā o ka mālama wela. Hoʻonui ʻo Silicon i ka pale ʻana i ka oxidation ʻoiai e hōʻemi ana i ka scaling i nā wela kiʻekiʻe. Hoʻomaikaʻi ʻo Nitrogen i nā waiwai mechanical e like me ka ikaika tensile a me ka ikaika hua.

Hāʻawi kēia hui ʻokoʻa o nā mea i ka 409 stainless steel maikaʻi loa i nā waiwai hoʻonui wela, e kūpono ana i nā noi wela kiʻekiʻe me ka ʻole o ka hoʻohālikelike ʻana i kona kūpaʻa a i ʻole ka dimensional paʻa. Hāʻawi pū kāna hui kemika i ka weldability maikaʻi, maʻalahi i nā kaʻina hana.

He mea koʻikoʻi ka hoʻomaopopo ʻana i ke ʻano kemika o 409 stainless steel i ka hoʻoholo ʻana i kona kūpono no nā noi kikoʻī, kahi e pono ai e noʻonoʻo ʻia nā mea e like me ka wela a me ka pale ʻana i ka corrosion.

Nā Pono o 409 Kuleana kila - Heat Resistance

ka pale wela o 409 kila kuhiliʻole ʻo ia kekahi o nā hiʻohiʻona koʻikoʻi e lilo ia i koho kaulana no nā noi like ʻole. Hiki i kēia ʻano o ke kila kila ke kū i nā wela kiʻekiʻe me ka ʻole o ka nalowale ʻana o kona kūpaʻa ʻana a i ʻole ka ʻike ʻana i ka deformation nui.

ʻO ke kūpaʻa wela o ka 409 stainless steel hiki ke hoʻopili ʻia i kāna ʻano kemika, aia ka nui o ka chromium a me kahi liʻiliʻi o ke kalapona. ʻO ka hele ʻana o ka chromium e hoʻokumu i kahi ʻāpana oxide pale ma luna o ka ʻili, i kapa ʻia ʻo passivation film, e kōkua i ka pale ʻana i ka oxidation a me ka corrosion i nā wela kiʻekiʻe.

Ma waho aʻe o kona kūpaʻa wela maikaʻi loa, hōʻike pū ka 409 stainless steel i ka conductivity thermal maikaʻi. 'O ia ho'i, hiki iā ia ke alaka'i maika'i i ka wela mai ke kumu wela, a laila e hō'emi ana i ka hopena o ka wela a me ka pō'ino.

Eia kekahi, ma muli o kāna microstructure ferritic, mālama kēia papa i kona ikaika a hiki i nā wela kiʻekiʻe. Uaʻikeʻia nā kila kila Ferritic no ko lākou hiki ke mālama i nā mea mechanical ma lalo o nā kūlana wela.

Me kēia mau mea hoʻohiwahiwa wela, hoʻohana nui ʻia ʻo 409 stainless steel i nā ʻōnaehana kaʻa a me nā kaʻa kaʻa, kahi e ʻike ʻia ai i ka wela nui i hana ʻia e nā kinoea hoʻopau engine. Hoʻohana ʻia ia i nā umu ʻoihana, nā mea hoʻomehana, a me nā mea ʻē aʻe e pono ai ka hana hilinaʻi ma nā wela kiʻekiʻe.

Nā waiwai o ka 409 Stainless Steel - Kū'ē Kū'ē

He ʻano koʻikoʻi ka pale ʻana i ka corrosion e noʻonoʻo i ke koho ʻana i ke kila kila no nā noi like ʻole. I ka hihia o 409 stainless steel, hōʻike ia i ke kūpaʻa corrosion maikaʻi ma nā wahi he nui.

ʻO kekahi o nā kumu o kona pale ʻana i ka corrosion ʻo kona kiʻekiʻe chromium maʻiʻo. Hoʻokumu ʻo Chromium i kahi papa oxide pale ma ka ʻili kila e lilo i mea pale e kūʻē i nā mea corrosive e like me ka wai a me nā kemika. Kōkua kēia ʻāpana oxide i ka pale ʻana i ka ʻōpala a hoʻonui i ke ola lawelawe o ka mea.

ʻO kekahi pōmaikaʻi ʻē aʻe o 409 stainless steel ʻo kona kūʻē ʻana i ke koʻikoʻi-corrosion māwae. Hana ʻia kēia ʻano ʻino inā loaʻa nā koʻikoʻi tensile a loaʻa nā kūlana kūlohelohe e like me ka ʻike ʻana i nā chlorides a i ʻole sulfides. ʻO ke ʻano ʻokoʻa o ka 409 stainless steel e kūpaʻa loa i kēia ʻano o ka pōʻino.

Eia kekahi, ʻo ka 409 stainless steel he kūpaʻa maikaʻi loa i ka corrosion o ka lewa, kūpono ia no nā noi waho e ʻike ʻia i nā kūlana ʻino. Hiki iā ia ke pale i ka ʻike lōʻihi i ka makū, ka paʻakai paʻakai, a me nā mea ʻino ʻē aʻe i loaʻa mau i nā kaiapuni waho.

Me kona kūpaʻa ʻana i ka corrosion ikaika, ua hōʻoia ʻo 409 stainless steel iā ia iho he koho hilinaʻi no nā ʻoihana like ʻole e pono ai ka pale ʻana i ka corrosion, e like me nā ʻōnaehana exhaust automotive, catalytic converters, heat exchangers, a me nā noi ʻē aʻe e ʻike ʻia i nā kūlana corrosive.

Mahalo iā ʻoe no ka heluhelu ʻana i kā mākou ʻatikala a ke manaʻo nei mākou e hiki ke kōkua iā ʻoe e hoʻomaopopo maikaʻi i ka haku mele a me nā waiwai o 409 stainless steel. Inā makemake ʻoe e ʻike hou aku e pili ana i ka 409 Stainless Steel, makemake mākou e aʻo iā ʻoe e kipa Kinohi Pilikino Sino.

Ma ke ʻano he alakaʻi alakaʻi o 409 mau mea kila kila ma ka honua holoʻokoʻa, hāʻawi ʻo Sino Stainless Steel i nā mea kūʻai aku me ka 201 Stainless Steel Strip & 304 Stainless Steel Strip, 409 Stainless Steel, 316 a me 316L kila kila, Bara Hexagon Kuhiliʻole, ʻO nā ʻōwili hao ʻili wela i ʻōwili ʻia, Pepa kila kuhiliʻole kala, Kila kohu ʻole Pepa Pua, Nā Paʻa Angle Keleawe kila, Nā ʻāpana kila kūpilikiʻi i ʻōwili ʻia anu, Wili kala kila, a Nā Papa Kūleʻa Pilikino ma ke kumu kūʻai hoʻokūkū loa.
