He kila kila 253 MA
ʻO Stainless 253 MA kahi huila lean austenitic heat resistant me ka ikaika kiʻekiʻe a me ke kūpaʻa kūʻokoʻa. Mālama ʻo 253 MA i kāna mau waiwai pale wela ma o ka mana holomua o nā hoʻohui micro alloy. ʻO ka hoʻohana ʻana i nā metala honua laha ʻole i hui pū ʻia me ke silika e hāʻawi i ka pale ʻana o ka oxidation maikaʻi a hiki i 2000°F. ʻO ka Nitrogen, carbon a me ka hoʻopuehu ʻana o ka honua kakaʻikahi a me ka alkali metala oxides i hui pū ʻia e hāʻawi i ka ikaika rupture creep e like me nā alloys base nickel. ʻO nā ʻano mea like ʻole e koi ana i ka ikaika kiʻekiʻe ma nā wela kiʻekiʻe e like me nā mea hoʻololi wela, nā kiln, nā mea hoʻomoe a me nā ʻāpana umu he mau noi maʻamau no 253 MA.

ʻO kekahi mau hiʻohiʻona o 253 MA
- ʻOi aku ka maikaʻi o ka pale ʻana i ka oxidation i 2000°F
- Kiʻekiʻe creep-rupture ikaika
He aha ke ʻano o nā noi i hoʻohana ʻia ʻo 253 MA?
- ʻO nā mea kuni ahi, nā ʻūhā paila
- ʻO nā paipu petrochemical a me ka hoʻomaʻemaʻe
- Nā mea hoʻololi wela
- Hoʻonui i lalo
- Hoʻopaʻa dampers
