ʻO UNS S31254 mau paipu kila kila. ʻO UNS S31254 kahi kila kila austenitic super me kahi kiʻekiʻe o ka molybdenum a me ka nitrogen, e hāʻawi ana i ke kū'ē kiʻekiʻe i ka pitting a me ka crevice corrosion a me ka ikaika kiʻekiʻe i hoʻohālikelike ʻia me nā kila kila austenitic maʻamau e like me 316L. ʻO UNS S31254 kahi papa austenitic kahi e hāʻawi ai ka hoʻohui ʻana o chromium, molybdenum a me ka nitrogen i ke kū'ē kiʻekiʻe i ka pitting i ka wai kai. Loaʻa i kēia alloy kahi awelika Pitting Resistance Equivalent Number ('PREN' = Cr+3.3Mo+16N) o 43.8. Hōʻike nā hoʻokolohua i ke kū'ē kiʻekiʻe i ka hoʻouka kaua crevice-corrosion i loko o ka wai kai a me ka stress corrosion cracking i loko o ka sodium chloride wela. Ke hoʻohālikelike ʻia me nā kila CrNiMo 17 12 2.5, hōʻike ia i ke kū'ē ʻana i ka corrosion maikaʻi loa i nā waikawa he nui i nā ʻano like a ʻo kona ikaika hua he 50% kiʻekiʻe. Weldability maikaʻi me ka hoʻohana ʻana i nā mea hoʻopau Ni-Cr-Mo. ʻO ka hoʻoheheʻe ʻana i ka wai a me nā wā pōkole i loko o ka pae 600-1000°C e pale aku i ka hiki ke hoʻomohala ʻia o ka pae sigma deleterious, ka mea e hoʻopōʻino ai a hoʻopilikia i ke kūpaʻa ʻana i ka pala.
