ʻO 253MA kahi papa e hui pū ana i nā waiwai lawelawe maikaʻi loa i nā wela kiʻekiʻe me ka maʻalahi o ka hana. Ke kū'ē nei ia i ka hoʻohāhā ʻana ma nā mahana a hiki i 1150°C a hiki ke hāʻawi i ka lawelawe ʻoi aku ma mua o ka Papa 310 i loko o ke kalapona, nitrogen a me ka sulfur i loko o nā lewa.

ʻO 2111HTR kekahi inoa ponoʻī e uhi ana i kēia papa.

Loaʻa i ka 253MA nā mea nickel haʻahaʻa haʻahaʻa, e hāʻawi iā ia i kahi pōmaikaʻi i ka hoʻohaʻahaʻa ʻana i nā ea sulphide ke hoʻohālikelike ʻia me nā alloys nickel kiʻekiʻe a me ka Grade 310. ʻO ka hoʻokomo ʻana i nā mea silika kiʻekiʻe, nitrogen a me cerium e hāʻawi ai i ke kila maikaʻi oxide stability, kiʻekiʻe kiʻekiʻe kiʻekiʻe wela ikaika a maikaʻi loa. kū'ē i ka ua ʻāpana sigma.

Hāʻawi ke ʻano austenitic i kēia papa i ka paʻakikī maikaʻi loa, a hiki i nā mahana cryogenic.

Na Waiwai Ki

Kuhi ʻia kēia mau waiwai no ka huahana ʻōwili palahalaha (pāla, pepa a me ka coil) e like me ka Grade S30815 ma ASTM A240/A240M. Ua kuhikuhi ʻia nā waiwai like akā ʻaʻole like no nā huahana ʻē aʻe e like me ka paipu a me ka bar i kā lākou kikoʻī.

Huina

Hāʻawi ʻia nā pae haku mele maʻamau no nā kila kila kila 253MA ma ka papa 1.
