he aha ka ʻokoʻa ma waena o 410 & 410S kila kila

ʻO ka ʻokoʻa nui ma waena o 410 a me 410S stainless steel aia i kā lākou ʻike kalapona a me kā lākou mau noi i manaʻo ʻia.

ʻO 410 ke kila kila he kila kila maʻamau i loaʻa ka liʻiliʻi o 11.5% chromium. Hāʻawi ia i ka pale corrosion maikaʻi, ka ikaika kiʻekiʻe, a me ka paʻakikī. Hoʻohana pinepine ʻia i nā noi e koi ana i ke kūpaʻa corrosion maʻalahi a me nā waiwai mechanical kiʻekiʻe, e like me nā valves, pumps, fasteners, a me nā ʻāpana no ka ʻoihana ʻaila.

Ma ka ʻaoʻao ʻē aʻe, ʻo 410S stainless steel kahi hoʻololi haʻahaʻa-carbon o 410 stainless steel. Loaʻa iā ia kahi maʻi kalapona haʻahaʻa (ma kahi o 0.08%) i hoʻohālikelike ʻia me 410 (0.15% kiʻekiʻe). ʻO ka mea i hoʻemi ʻia ke kalapona e hoʻomaikaʻi i kona weldability a ʻoi aku ka pale ʻana i ka sensitization, ʻo ia ka hoʻokumu ʻana o nā chromium carbide ma nā palena o ka palaoa e hiki ke hōʻemi i ka pale ʻana i ka corrosion. ʻO ka hopena, ʻoi aku ka maikaʻi o ka 410S no nā noi kahi e koi ʻia ai ka welding, e like me nā pahu annealing, nā ʻāpana umu, a me nā noi wela kiʻekiʻe.

I ka hōʻuluʻulu ʻana, ʻo nā ʻokoʻa nui ma waena o 410 a me 410S stainless steel ʻo ia ka ʻike kalapona a me kā lākou mau noi. ʻO ka 410 he kila kila kila me ka ʻoi aku ka nui o ke kalapona, ʻoiai ʻo 410S kahi ʻano kalapona haʻahaʻa e hāʻawi i ka weldability maikaʻi a me ke kūpaʻa ʻana i ka sensitization.
