2507 / s32750 / 1.4410

ʻO 2507 kahi kila kila kila super duplex me ka ʻoi aku o ka alloy kiʻekiʻe, no laila e ʻoi aku ka maikaʻi ma mua o 2205 i ka pale ʻana a me ka ikaika. He kūpaʻa maikaʻi loa ia i ka ʻaʻahu, pitting, crevice corrosion a me ka chloride stress corrosion cracking. I loko o ka dilute sulfuric acid i haumia me ka chloride ions, 2507 i ʻoi aku ka maikaʻi o ka corrosion ma mua o 904L, i hoʻolālā kūikawā ʻia e kūʻē i ka waikawa sulfuric maʻemaʻe. No ka mea, ʻo ka haʻahaʻa kalapona haʻahaʻa o 2507 e hoʻohaʻahaʻa loa i ka pilikia o ka carbide precipitation ma nā palena palaoa i ka wā o ka mālama ʻana i ka wela, ua kūpaʻa loa ia i ka carbide-related intergranular corrosion. ʻAʻole kūpono ʻo 2507 no nā noi e koi ana i ka lōʻihi o ka ʻike ʻana i nā mahana ma luna o 300 ℃ no ka piʻi nui ʻana o ka hōʻemi ʻana i ka paʻakikī. ʻO ka ikaika o kona hoʻoulu ʻana he ʻelua paha ia o ko nā kila kuhili ʻole austenitic maʻamau.

 

S32507 Duplex mea kila kila i hāʻawi ʻia e Beall Industry Group he ʻano kiʻekiʻe.

Hiki ke hāʻawi ʻia ka Bar, Pipe, Sheet a me Plate.
