ʻIkepili o ka paipu kila kila Alloy 430
430 kila kilaishe ferritic, chromium pololei, papa paʻakikī ʻole, e hoʻohui ana i ke kūpaʻa maikaʻi o ka corrosion a me nā ʻano formability me nā waiwai mechanical pono. ʻO kona hiki ke kūʻē i ka hoʻouka ʻana o ka waikawa nitric e ʻae i kona hoʻohana ʻia ʻana i nā noi kemika kikoʻī, akā ʻo nā ʻāpana trim a me nā mea hana kaʻa e hōʻike ana i kāna mau kahua noi nui loa. Loaʻa i ke kila kila kila 430 ke kūpaʻa maikaʻi i ka corrosion i hui pū ʻia me ka formability maikaʻi. Ua like loa ʻo 430 me ke kila kila kila 439 me ka chromium liʻiliʻi iki ma ka 16% ka liʻiliʻi o ka ʻike. ʻOi aku ka pale ʻana o 430 i ka oxidation a me ka pale ʻana i ka corrosion ma mua o 409 grade. ʻO 430 kahi papa paʻakikī ʻole kaulana i hoʻohana pinepine ʻia i nā wahi o loko. Hoʻokumu koke ʻia ʻo 430 e ke kūlou ʻana, ka huki hohonu a me ka hoʻolālā ʻana. He maʻalahi ka mīkini ʻana o 430 a ua like ia me ke kila kalapona kūkulu e koi ana i nā ʻōlelo aʻoaʻo like e pili ana i ka mea hana, nā wikiwiki ʻoki a me nā hānai ʻoki. Hiki ke hoʻopaʻa ʻia ʻo 430 ʻoiai pono paha ka annealing.
ʻOkoʻa ma waena o ke kila kila 304 a me 430
ʻO kekahi o nā papa kaulana loa o ke kila kila ferritic me nā ʻano magnetic ʻo 430. ʻO ka papa kaulana loa o ke kila kila me nā ʻano non-magnetic ʻo 304. Loaʻa i ka hui 430 ka hao me ka liʻiliʻi ma mua o 1% nickel, a hiki i ka 18% chromium, silicon, phosphorus, sulfur, a me manganese. Me 18% chromium, carbon, manganese, silicon, phosphorus, sulfur, nitrogen, a me ka hao, loaʻa i ka 304 he 8% nickel.
ʻO ka ikaika haʻahaʻa loa a me ka ikaika tensile o nā mea 304 he 215 MPa a me 505 MPa, kēlā me kēia, mahalo i kēia ʻano kemika. ʻO ka ikaika haʻahaʻa loa a me ka ikaika tensile o ka mea 430 a hiki i ka 260 MPa a me 600 MPa, kēlā me kēia. Loaʻa i ka 430 kahi kiko heheʻe e hiki ke piʻi i 1510 degere Celsius. ʻOi aku ka paʻa o ka mea 304 ma mua o ka 430.
