Ma waena o nā ʻano like ʻole o ke kila kila, hoʻohana mau ʻia nā māka 304, 304L, a me 304H. ʻOiai ke ʻano like lākou, loaʻa i kēlā me kēia papa kona mau waiwai ponoʻī a me nā noi.
Papa304 kila kilaʻo ia ka mea i hoʻohana nui ʻia a maʻalahi hoʻi o ka 300 series stainless steels. Loaʻa iā ia ka 18-20% chromium a me ka 8-10.5% nickel, me ka liʻiliʻi o ke kalapona, manganese, a me ke silika. He maikaʻi ke kūpaʻa corrosion a me ka formability maikaʻi. Hoʻohana pinepine ʻia i nā noi e like me nā lako kīhini, ka hoʻoili ʻana i ka meaʻai, a me ka hoʻonaninani hale.
304L paipu kila kilahe paipu kila kalapona haʻahaʻa o ka papa 304, me ka nui o ka maʻiʻo kalapona he 0.03%. ʻO kēia haʻahaʻa kalapona haʻahaʻa e kōkua i ka hōʻemi ʻana i ka carbide precipitation i ka wā wili, kūpono ia no nā noi wili. ʻO ka haʻahaʻa kalapona e hōʻemi ana i ka pilikia o ka sensitization, ʻo ia ka hoʻokumu ʻana o nā chromium carbide ma nā palena palaoa, hiki ke alakaʻi i ka corrosion intergranular. Hoʻohana pinepine ʻia ʻo 304L i nā noi welding, a me nā kaiapuni kahi e hopohopo ai ka pilikia o ka corrosion, e like me ka hana kemika a me nā lako lāʻau.
304H kila kilaʻO ia ka mana kalapona kiʻekiʻe o ka papa 304, me ka maʻiʻo kalapona mai ka 0.04-0.10%. ʻO ka maʻiʻo kalapona kiʻekiʻe e hāʻawi i ka ikaika wela kiʻekiʻe a me ke kūpaʻa kolo. Hana kēia i ka 304H kūpono no nā noi wela kiʻekiʻe, e like me nā ipu kaomi, nā mea hoʻololi wela, a me nā paila ʻoihana. Eia nō naʻe, ʻoi aku ka maʻalahi o ka maʻi kalapona kiʻekiʻe i ka 304H i ka sensitization a me ka corrosion intergranular, ʻoi aku hoʻi i nā noi wili.
I ka hōʻuluʻulu ʻana, ʻo ka ʻokoʻa nui ma waena o kēia mau māka ʻo kā lākou ʻike kalapona a me ka hopena i ka wili a me nā noi wela kiʻekiʻe. ʻO ka papa 304 ka mea i hoʻohana nui ʻia a maʻamau, ʻoiai ʻo 304L ka koho i makemake ʻia no nā noi wili a me nā wahi kahi e hopohopo ai ka corrosion. Loaʻa i ka 304H ka ʻona kalapona kiʻekiʻe a kūpono ia no nā noi wela kiʻekiʻe, akā ʻo kona maʻalahi i ka sensitization a me ka corrosion intergranular pono e noʻonoʻo pono. Ke koho ʻana ma waena o kēia mau māka, he mea nui e noʻonoʻo i nā koi kikoʻī o ka noi, e komo pū me ka ʻenehana hana, ka mahana, a me nā pono welding.
E leka uila iā mākou no ka ʻike hou aku
