304 pā kila kila waiwai kumu:
Ka ikaika uʻi (Mpa) 520
Ka ikaika hua (Mpa) 205-210
Elongation (%) 40%
Oolea HB187 HRB90 HV200
304 kila kuhiliʻole mānoanoa 7.93 g / cm3 austenitic kuhiliʻole kila hoʻohana maʻamau i kēia waiwai 304 chromium maʻiʻo (%) 17.00-19.00, nickel maʻiʻo.%) 8.00-10.00,304 like me Kina 0Cr19Ni9 (0Cr18Ni9) kila kila.
ʻO ka 304 stainless steel he mea kila kila nui, hana anti-rust ma mua o ka 200 series o nā mea kila kila e ikaika. ʻOi aku ka maikaʻi o ka wela kiʻekiʻe.
ʻO 304 kila kila maikaʻi loa ka pale ʻana i ka corrosion a me ke kūpaʻa maikaʻi i ka corrosion intergranular.
Ma ka oxidation o ka waika, i loko o ka hoʻokolohua hoʻoholo 'ia: kuʻina ≤ 65% o ka paila ana wela o ka nitric waika, 304 kuhiliʻole kila i ikaika corrosion kū'ē. ʻO ka solution alkaline a me ka hapa nui o nā ʻakika organik a me nā ʻakika inorganic pū kekahi me ke kūpaʻa ʻino maikaʻi.
Nā hiʻohiʻona maʻamau
ʻO 304 ke kila kila kila a me ka hiki ke hoʻololi.
ʻOi aku ka maikaʻi ma mua o ke kila maʻamau, kūpaʻa maikaʻi i ka corrosion.
ʻO ka ikaika kiʻekiʻe, no laila ka hiki ke hoʻohana i ka pā lahilahi.
ʻO ka oxidation wela kiʻekiʻe a me ka ikaika kiʻekiʻe, no laila hiki ke ahi.
Ma ka lumi wela ka hana, maʻalahi ia e hana.
No ka mea ʻaʻole pono e hana me ia, maʻalahi a maʻalahi hoʻi e mālama.
Maʻemaʻe, hoʻopau kiʻekiʻe.
Maikaʻi ka hana welding.
