He aha kaʻokoʻa ma waena o nā mea kila stainless 304, 304l, 316 a 316 a 316l?

He aha ke kila kila?
ʻO keʻano stielless heʻano kila. ʻO ka Steel e pili ana i ke kila e loaʻa ana ma lalo o 2% carbon (c), a ma mua o 2% ka hao. Hoʻohui i ka chromium (cr), nickel (ni), marliese (mn), a iʻole nā mea hana'ē aʻe
He aha nā "kila" a me ka "hao", he aha nāʻano o lākou, a he aha ka pilina ma waena o lākou? Pehea ka 304, 304l, 316, a me 316l pinepine mākou e kamaʻilio e pili ana, a he aha kaʻokoʻa ma waena o lākou?
ʻO Steel: kahi mea me ka hao ma keʻano o ka mea nui, kaʻike o ka trabon ma lalo o 2%, a me nā mea'ē aʻe. --Gb / t 13304-91 "Steel Classification"
Iron: kahi mea metallic me ka helu atomika 26. Loaʻa nā mea hao i ka Ferromagnetism, maikaʻi loa, a me ka lapalapa maikaʻi.
ʻO nā mea kila maikaʻiʻole ʻO nā helu Steel maʻamau i hoʻohanaʻia he 304, 304l, 316, a me 316l,ʻo ia hoʻi he 300 series i nā kila hestentic.
No ke aha e loaʻa ai nā helu kila maikaʻiʻole?
I ka wā o keʻano snolting o nā kila kūponoʻole, ma muli o nāʻanoʻano'ē aʻe e hoʻohuiʻia,ʻokoʻa ka nui o nāʻano likeʻole. ʻOkoʻa nā hiʻohiʻona. I mea e hoʻokaʻawale ai iā lākou, ua pāpaleʻia nā heluʻokoʻa likeʻole. ʻO ka papa inoa o ka papa o ka "Alloy Element

O nā kila a pau, nā kila austetetitic e loaʻa ana i ka nui o ka hopena. No laila, e pili ana i nāʻano o nā mea hana mechanin,ʻo Austentitic Inselless ka mea maikaʻi loa, no ka mea, no ka mea, ke hoʻonui nei ka nui o ke kumu valve. ʻAʻole hiki ke hoʻonuiʻia ka manaʻo o ka hopena ma ka mālamaʻana i ka wela, akā hiki ke hoʻonuiʻia ma keʻano anuanu.

No ke aha ke kumu o nā mea kila kila?
No ke aha e hele ai ke kila kila? I ka manawa i kū ai nā bulaʻalani (nā kihi) ma luna o kaʻili o nā kila kila, he pīhoihoi lākou, a inā he pilikia paha ka meaʻoi aku ka maikaʻi o ka mea kila.
