PHKo te 13-8Mo he kowiri tira he martensitic precipitation whakapakeke he kowiri tira he pai rawa te kaha, te pakeke teitei, te pakari me te pai o te parenga waikura.Ko nga ahuatanga pai o te uaua whakawhiti ka tutuki ma te kaha o te whakahaere hanganga matū, te iti o te waro, me te rewa korehau.Ko nga tono angamaheni ko nga waahanga hanganga anga rererangi nui me nga taputapu whakarewa werohanga.

•Te kaha teitei, te pakari o te pakaru, nga ahuatanga miihini whakawhiti me te awangawanga te waikura i te taiao moana.
•Weldability: Ma te weriweri whakamarumaru hau koretake, ma te whakamahi i te nuinga o etahi atu o nga mahi whakapiri, tae atu ki te raima plasma,te whakapiri irahiko kurupae, A he pai ake te hau whakamarumaru argon.
Ka whakamahia nuitia i roto i te aerospace, reactors karihi me te petrochemical me etahi atu mara, penei i nga whakamaarama upoko makariri me
te miihini, nga waahanga rererangi, nga waahanga reactor me te petrochemical equipment.
