Ke nānā 'ana i nā 'oko'a ma waena o nā mea ho'opa'a kila kila a me Carbon

I loko o ke ʻano o nā huahana plastik, pili ka mea o nā wili i nā mea i koi ʻia e ka huahana, e like me ka nui o ka ikaika, a hoʻohana ʻia ke kila kuhili ma waho o ka plastic, a hoʻohana ʻia nā wili kila carbon ma ka i loko.Pehea e koho ai i ke kila kila?

1: Ma ka ʻōlelo a ka poʻe kamaʻāina, ʻaʻohe kila me nā mea hoʻohui i hoʻohui ʻia, a ʻo nā wili kila kila he kila me nā mea hoʻohui kiʻekiʻe i hoʻohui ʻia no ka pale ʻana i ka ʻōpala.
2: ʻOi aku ke kumu kūʻai o nā wili kila kila ma mua o nā wili kila.
3: He ʻokoʻa kēia mau ʻano ʻelua, no laila ʻaʻole hiki ke hoʻohālikelike ʻia.ʻOi aku ka ikaika o nā wili kila kalapona ma mua o nā wili kila kila, akā maʻalahi lākou i ka ʻōpala.

ʻOkoʻa nā mea o nā wili kila kila a me nā mea kila kalapona, a ʻokoʻa hoʻi ke ʻano o ka hoʻohana ʻana.ʻAʻole maikaʻi ke kūpaʻa ʻana o ke kila kalapona, a e ʻōpala nā bolts i ka make ma hope o ka manawa lōʻihi.ʻOi aku ka maikaʻi o nā wili kila kila.

wili kila kila
ʻOkoʻa nā mea hana o nā wili kila a me nā mea kila carbon, a ʻokoʻa hoʻi nā kaiapuni i hoʻohana ʻia ai.
He ʻilihune ka pale ʻana o ke kila kalapona, a ʻeleʻele nā ​​bolts i ka make ma hope o ka manawa lōʻihi.ʻOi aku ka maikaʻi o nā pōkā kila kila.Eia kekahi mau mea no na wili kila kuhilihi.

ʻO ka hoʻokaʻawale ʻana o nā mea kila kila
Hoʻohana ʻia ia no ka hana ʻana i nā wili kila kila.Hoʻokaʻawale ʻia nā mea o nā wili kila i loko o ka austenitic stainless steel, ferritic stainless steel, martensitic stainless steel and precipitation hardening stainless steel.ʻO ke koho ʻana i nā ʻili kila kila ma ke kumu.Mai ka ʻaoʻao hea, e koho ʻoe i nā wili kila kila āu e pono ai.

Ma hope o ka noʻonoʻo piha ʻana i kēia mau ʻano ʻelima, ua hoʻoholo hope ʻia ka pae, nā ʻano like ʻole, nā kikoʻī a me nā mea maʻamau o nā wili kila kila.

He kila kuhiliʻole Ferritic
ʻOi aku ka maikaʻi o ke kila chromium type 430 ma mua o ka Type 410, akā ʻaʻole hiki ke hoʻoikaika ʻia e ka mālama wela.He kūpono ia no ke kila kuhiliʻole me ka pale ʻana i ka corrosion kiʻekiʻe aʻe a me ka pale wela a me nā koi ikaika maʻamau.wiliwili.

Ke kila kila ʻole Martensitic
Hiki ke hoʻoikaika ʻia ka Type 410 a me Type 416 e ka mālama wela, me ka paʻakikī o 35-45HRC a me ka machinability maikaʻi.He mau wili kila kuhiliʻole ka wela a me ka corrosion no nā kumu maʻamau.'O ka 'ano 416 ka mea i 'oi a'e ka nui o ka sulfur a he kila kuhili ma'alahi ke 'oki.

ʻAno 420, maʻiʻo sulfur ?ʻO R0.15%, hoʻomaikaʻi ʻia nā waiwai mechanical, hiki ke hoʻoikaika ʻia e ka mālama ʻana i ka wela, ka waiwai paʻakikī kiʻekiʻe 53 ~ 58HRC, hoʻohana ʻia no nā wili kila kila e koi ana i ka ikaika kiʻekiʻe.

wili kila kila
Ua hoʻopaʻa ʻia ke kila kila
17-4PH, PH15-7Mo, hiki iā lākou ke kiʻi i ka ikaika kiʻekiʻe ma mua o ka 18-8 mau mea kila kila, no laila hoʻohana ʻia lākou no ka ikaika kiʻekiʻe.

ʻO A-286, he kila kuhiliʻole maʻamau, ʻoi aku ka nui o ka pale ʻana i ka corrosion ma mua o ka mea maʻamau 18-8 type stainless steel, a me nā waiwai mechanical maikaʻi i nā mahana kiʻekiʻe.Hoʻohana ʻia ia e like me ka ikaika kiʻekiʻe, ka wela a me ka corrosion-resistant stainless steel screws, hiki ke hoʻohana ʻia a hiki i 650-700 °C.

wili kila kila
Austenitic kila kila
ʻO nā māka maʻamau ʻo 302, 303, 304, a me 305, ʻo ia nā māka ʻehā o ka mea i kapa ʻia ʻo "18-8" austenitic stainless steel.ʻO ke kūpaʻa corrosion paha, a i ʻole kona mau ʻano mechanical.ʻO ka hoʻomaka ʻana no ke koho ʻana ʻo ke ʻano hana hana o nā wili kila kila, a ʻo ke ʻano e pili ana i ka nui a me ke ʻano o nā wili kila kila, a pili pū i ka nui o ka hana.

Hoʻohana ʻia ke ʻano 302 no nā wili mīkini a me nā bolts paʻi ponoʻī.
ʻAno 303 I mea e hoʻomaikaʻi ai i ka hana ʻoki ʻana, hoʻohui ʻia kahi liʻiliʻi o ka sulfur i ke kila kila kila Type 303, i hoʻohana ʻia no ka hoʻoponopono ʻana i nā nati mai ka waihona bar.
He kūpono ke ʻano 304 no ka hoʻoponopono ʻana i nā wili kila kila ma ke kaʻina hana poʻomanaʻo wela, e like me nā bolts kikoʻī lōʻihi a me nā bolts anawaena nui, ʻoi aku paha ma mua o ke ʻano o ke kaʻina hana poʻo anu.

He kūpono ke ʻano 305 no ka hoʻoponopono ʻana i nā wili kila ma ke kaʻina poʻomanaʻo anu, e like me nā nuts i hana ʻia a me nā bolts hexagonal.

ʻO Type 309 a me Type 310 he kiʻekiʻe aʻe ka Cr a me Ni ma mua o Type 18-8 stainless steel, a ua kūpono i nā wili kila kila e hana ana i nā wela kiʻekiʻe.

ʻO nā ʻano 316 a me 317, loaʻa iā lākou ʻelua alloying element Mo, no laila ʻoi aku ka kiʻekiʻe o ko lākou ikaika wela a me ke kūpaʻa corrosion ma mua o 18-8 stainless steel.

ʻO Type 321 a me Type 347, Type 321 i loaʻa iā Ti, kahi mea hoʻohui paʻa paʻa, a ʻo Type 347 i loaʻa iā Nb, kahi e hoʻomaikaʻi ai i ka pale ʻana o ka corrosion intergranular o ka mea.He kūpono ia no nā ʻāpana maʻamau kila kila ʻaʻole i hoʻopili ʻia ma hope o ke kuʻi ʻana a i ʻole i ka lawelawe ma 420-1013 °C.
