1.Hāʻawi i nā ikaika kiʻekiʻe ma mua o ka austenitic a me 22% Cr Duplex Stainless Steels UNS S32760 (F55) kūpono i nā ʻano noi like ʻole i nā ʻoihana e like me Oil & Gas, CPI (Chemical Processing Industries), a me nā kaiapuni moana.

Ua helu ʻia ʻo UNS S32760 (F55 / 1.4501) ma NACE MR 01 75 no ka lawelawe ʻawaʻawa a loaʻa iā ia ka ʻae ʻana o ASME no nā noi Pressure Vessel.

nā pae ikaika ma o nā hana wela maʻalahi i nā Kūlana RH 950 a me TH 1050. ʻO ka ikaika kiʻekiʻe kiʻekiʻe o Condition CH 900 e hāʻawi i nā pono he nui kahi e ʻae ʻia ai ka ductility a me ka hana.Ma kona kūlana i mālama ʻia me ka wela, hāʻawi kēia huila i nā waiwai mechanical kūikawā ma nā mahana a hiki i 900 °F (482 °C).
