ʻO 253MA (UNS S30815) he kila austenitic kūpaʻa wela i hoʻolālā ʻia no nā noi e koi ana i ka ikaika kiʻekiʻe a me ke kūpaʻa ʻana i ka corrosion maikaʻi. ʻO 850 ~ 1100 °C kāna hana wela.
ʻO ka hui kemika o 253MA he kaulike, kahi e hana ai ke kila i ka hana piha kūpono loa i ka pae wela o 850 ° C-1100 ° C, kiʻekiʻe kiʻekiʻe oxidation kū'ē, oxidation wela a hiki i 1150 ° C, a kiʻekiʻe kiʻekiʻe creep kū'ē. ʻO ka hiki a me ka ikaika o ka haki ʻana; kūpaʻa maikaʻi loa i ka corrosion wela kiʻekiʻe a me ka pale ʻana i ka corrosion i ka nui o nā media kinoea; ka ikaika kiʻekiʻe a me ka ikaika tensile i nā wela kiʻekiʻe; maikaʻi formability a weldability, a lawa machinability.
Ma waho aʻe o nā mea hoʻohui chromium a me nickel, loaʻa i ka 253MA stainless steel kahi liʻiliʻi o nā metala honua laha ʻole, a laila e hoʻomaikaʻi nui ai i kona mana antioxidant. Hoʻohui ʻia ka Nitrogen e hoʻomaikaʻi i nā waiwai kolo a hana i kēia kila austenite. ʻOiai he haʻahaʻa ka chromium a me ka nickel i loko, ʻo ia mau kila kuhiliʻole i nā manawa he nui nā ʻano wela kiʻekiʻe e like me nā mea hoʻoheheʻe ʻia i hoʻohui ʻia nui ʻia a me nā mea hao kumu nickel.
