304 / 304L ʻO ke kila kila ʻole ʻia

ʻO Alloys 304 (S30400) a me 304L (S30403) nā ʻano kila kila he ʻano like ʻole o ka 18 pākēneka chromium - 8 pākēneka nickel austenitic alloy, ka mea i kamaʻāina a hoʻohana pinepine ʻia i ka ʻohana kila kila. ʻO 304/L nā mea kila kila maikaʻi loa. ʻO kona malleability hiki iā ia ke hana maʻalahi no ka flaring, ka piko a me ka wili. ʻO ka machinability maikaʻi a me ka ʻike sulfur haʻahaʻa e hāpai i ka weldability maikaʻi loa i nā noi e pono ai.

ʻO ka ikaika kiʻekiʻe, ka pale ʻana i ka corrosion maikaʻi a me ka maʻi kalapona liʻiliʻi e hoʻohana i ka Alloy 304 a me 304L Stainless Steels i mea pono no nā noi kahi e pono ai ka wili. Hoʻohana ʻia nā mea hoʻoheheʻe a me ka ʻokiʻoki, nā ʻāpana welded o ke kemika, textile, pepa, lāʻau lapaʻau a me nā mea hana ʻoihana kemika.

ʻO nā mea maikaʻi ʻē aʻe ʻo kona kūpaʻa ʻana i ka oxidation, ʻano maikaʻi loa, maʻalahi o ka hana ʻana a me ka hoʻomaʻemaʻe ʻana, ka ikaika maikaʻi i ka ratio paona a me ka paʻakikī maikaʻi i nā mahana cryogenic No nā kaiapuni koʻikoʻi, ʻoi aku ka haʻahaʻa o ka Type 304L no ka nui o kona pale ʻana i ka intergranular corrosion.

ʻO ke kila kila 304L ʻano he ʻano kalapona haʻahaʻa haʻahaʻa o ke kila 304huikau. ʻO ka haʻahaʻa kalapona ma 304L e hōʻemi i ka ua carbide pōʻino a ʻino paha ma muli o ka wili. No laila, hiki ke hoʻohana ʻia ʻo 304L "e like me ka welded" i nā wahi ʻino koʻikoʻi, a hoʻopau ia i ka pono no ka annealing.

He haʻahaʻa haʻahaʻa haʻahaʻa kēia papa ma mua o ka papa 304 maʻamau, akā hoʻohana nui ʻia no kona versatility. E like me ka Type 304 stainless steel, hoʻohana maʻamau ia i ka hana pia a me ka hana waina, akā no nā kumu ma waho aʻe o ka ʻoihana meaʻai e like me nā ipu kemika, mining, a me ke kūkulu ʻana. He kūpono ia no ka hoʻohana ʻana i nā ʻāpana metala e like me nā nati a me nā bolts i ʻike ʻia i ka wai paʻakai.
