ʻO 409 ke kila kila kila?

ʻO ke kila kila he mea kaulana i hoʻohanaʻia i nāʻoihana likeʻole ma muli o kona kūpaʻa a me ka lōʻihi. Ma waena o nā ʻano ʻano kila kila, ʻo 409 kahi māka kikoʻī i hoʻohana pinepine ʻia i nā noi kahi e manaʻo ʻia ai ka ʻike ʻana i nā kaiapuni corrosive. Eia naʻe, ʻo kahi nīnau maʻamau e kū mai ana i ka wā e noʻonoʻo ai i kēia mea inā he magnetic a i ʻole 409 stainless steel.

 

ʻO ke kila kila 409

ʻO ka 409 stainless steel he chromium-nickel alloy nona ka ʻohana ferritic o nā kila kila. Loaʻa iā ia ma waena o 10.5% a me 11.7% chromium, kahi mea e pale ai i ka corrosion, a me kahi nickel liʻiliʻi, ma kahi o 0.5%. Eia naʻe, ʻo ka ʻokoʻa koʻikoʻi ma waena o 409 a me nā ʻāpana kila kila ʻē aʻe, ʻo ia kona ʻano kalapona, ʻoi aku ka kiʻekiʻe ma mua o ka nui o nā māka kila kila.

 

Mea Magnetic o 409 Kuleana kila

He kuleana koʻikoʻi ka ʻike kalapona i ka 409 stainless steel i ka hoʻoholo ʻana i kāna mau waiwai magnetic. No ka mea he ʻoi aku ka nui o ke kalapona, ʻoi aku ka maʻalahi o ka hana ʻana i ka martensite, kahi pae ferromagnetic o nā ʻāpana hao-carbon. ʻO kēia hana martensite e hoʻonāwaliwali i ka 409 stainless steel.

I kēia manawa, koʻikoʻi ka huaʻōlelo "weakly magnetic" ma aneʻi. ʻOiai ʻaʻole ʻoi aku ka ikaika o ke kila kila 409 e like me nā mea hao hao ʻē aʻe, e hōʻike mau ana ia i kekahi degere o ka magnetism. ʻO kēia ma muli o ka loaʻa ʻana o nā mea ferromagnetic e like me ka hao a me ke kalapona i kāna ʻano.

 

Hoʻohana maʻamau o 409 kila kila

Hiki ke hoʻohana ʻia nā waiwai magnetic o 409 stainless steel i kona hoʻohana ʻana ma kekahi mau wahi kikoʻī. No ka laʻana, i nā mea uila a i ʻole nā ​​​​mea lapaʻau e pono ai e pale i ka hoʻopili ʻana i ke kahua magnetic, me ka hoʻohana ʻana i ka 409 stainless steel ʻaʻole paha ke koho maikaʻi loa. Ma nā kahua ʻē aʻe, e like me ke kūkulu ʻana a me ka hana ʻana o nā kaʻa, ʻaʻole nui ka hopena o kāna mau hiʻohiʻona.

 

Ka hopena

I ka hōʻuluʻulu ʻana, ʻo ka 409 stainless steel he palupalu palupalu ma muli o kāna ʻano kalapona a me ka hoʻokumu ʻana o martensite. ʻOiai ʻaʻole ia e like me ka ikaika e like me nā mea hao ʻē aʻe, e hōʻike mau ana ia i kekahi degere o ka magnetism. Pono e noʻonoʻo ʻia kēia i ka wā e noʻonoʻo ai i kāna hoʻohana ʻana i nā noi kahi e hopohopo ai ka magnetism.
