ʻO wai ke ʻano o ka pahu heleuma kemika ʻoi aku ka maikaʻi?

304 kila kuhiliʻole kino heleuma

ʻO 304 stainless steel kekahi o nā mea kila kila maʻamau a hoʻohana nui ʻia i ke kūkulu ʻana, nā lako kīhini a me nā māla ʻē aʻe. Loaʻa i kēia kŘkohu kila kila he 18% chromium a me 8% nickel, a he kūpaʻa maikaʻi ka corrosion, machinability, paʻakikī a me ka ikaika. He mea maʻalahi kēia kila kila i ka poli a me ka hoʻomaʻemaʻe, a he maʻemaʻe a nani hoʻi.

316 kila kuhiliʻole kino heleuma pahu

Hoʻohālikelike ʻia me 304 stainless steel, 316 stainless steel ka nui o ka nickel a me ka molybdenum a ʻoi aku ka nui o ke kūpaʻa corrosion. He kūpono ia no nā kaiapuni e like me ka wai kai, nā kemika, a me nā wai waikawa, no laila ua hoʻohana nui ʻia i ka ʻenekinia moana, ʻoihana kemika a me nā māla ʻē aʻe. Eia naʻe, ma muli o ke kiʻekiʻe o ke kila kila 316, ʻoi aku ka kiʻekiʻe o kona kumukūʻai ma mua o 304 stainless steel.

430 kila kuhiliʻole kino heleuma pahu

ʻO ke kila kila 430 he ʻano kila kila 18/0 ʻaʻole i loko o ka nickel akā loaʻa kahi mea chromium kiʻekiʻe a hoʻohana pinepine ʻia i mea hana no ka hana ʻana i nā lako kīhini a me nā papa ʻaina. ʻOiai ʻoi aku ka liʻiliʻi ma mua o 304 a i ʻole 316 stainless steel, ʻoi aku ka maikaʻi o ke kūpaʻa corrosion a me ka paʻakikī.

201 kila kuhiliʻole kino heleuma

ʻO ka 201 stainless steel ka liʻiliʻi o ka nickel a me ka chromium, akā aia a hiki i ka 5% manganese, ʻoi aku ka paʻakikī a me ka corrosion-resistant, kūpono no ka hana ʻana i nā huahana pale. Eia naʻe, ke hoʻohālikelike ʻia me 304 a me 316 stainless steel, ʻoi aku ka nāwaliwali o kona kūpaʻa corrosion.
