He aha ka ʻokoʻa ma waena o 304 a me 316 kila kila?

ʻO ke kila kila he metala kaulana a hoʻohana pinepine ʻia no ka hoʻomohala ʻana i ka paipu ma muli o kāna ʻano mea kemika a me nā waiwai. Loaʻa ke kila kila ma nā ʻano māka, nā mea a me nā kikoʻī e hoʻokō i nā pono ʻoihana āpau. ʻO SS 304 kekahi o nā kila kila non-magnetic a austenitic i hoʻohana nui ʻia, kūpono no ka hana ʻana i nā ʻano paipu āpau. Loaʻa ka 304 stainless steel tubing a me 316 stainless steel tubing i nā ʻano like ʻole e like me ka seamless, welded a me nā flanges.

304 kila kila a me kona hoʻohana
ʻO ke kila kila kila 304, me kona chromium-nickel a me ka haʻahaʻa carbon content, ʻo ia ka mea maʻalahi a hoʻohana nui ʻia o nā kila kuhili ʻole austenitic. ʻO kāna mau mea hoʻololi a pau o ka austenitic alloy me 18% chromium a me 8% nickel.
Ua hōʻike ʻia ʻo Type 304 i ka oxidation a me ka corrosion a paʻa.
Hoʻohana ʻia ʻo Type 304 stainless steel tubing i ka corrosion resistant electrical enclosures, automotive moldings and trim, wheel covers, kitchen appliances, hose clamps, exhaust manifolds, stainless steel hardware, storage tanks, pressure vessels and pipe.
316 kila kila a me kona hoohana ana
ʻO Type 316 stainless steel tubing he austenitic chromium-nickel stainless a me ka wela wela me ke kūpaʻa ʻoi aku ka maikaʻi o ka corrosion i hoʻohālikelike ʻia me nā kila chromium-nickel ʻē aʻe ke ʻike ʻia i nā ʻano corrosive kemika e like me ke kai, nā paʻakai a me nā mea like.
Aia ka molybdenum i loko o ka paipu huila SS type 316, e hāʻawi ana iā ia i ke kū'ē nui i ka hoʻouka kemika ma mua o ka Type 304. ʻO ke ʻano 316 ka lōʻihi, maʻalahi ke hana, hoʻomaʻemaʻe, weld a hoʻopau. ʻOi aku ka pale ʻana i nā hopena o ka sulfuric acid, chlorides, bromides, iodide a me nā momona momona i nā wela kiʻekiʻe.
Pono ka SS i loko o ka molybdenum i ka hana ʻana i kekahi mau lāʻau lapaʻau e pale aku ai i ka hoʻohaumia nui ʻana. ʻO ka laina lalo, ʻo 316 mau kila kila i loaʻa ka molybdenum e koi ʻia i ka hana ʻana i kekahi mau lāʻau lapaʻau e pale aku ai i ka hoʻohaumia nui ʻana.
