17-4PHʻO ka alloy he kila kila martensitic e hoʻopaʻakikī ana i ka ua, i haku ʻia me ke keleawe, niobium, a me ka tantalum. Nā ʻano: Ma hope o ka mālama ʻana i ka wela, hōʻike ka huahana i nā waiwai mechanical i hoʻomaikaʻi ʻia, e hoʻokō ana i ka ikaika compressive a hiki i ka 1100-1300 MPa (160-190 ksi). ʻAʻole kūpono kēia papa no ka hoʻohana ʻana i nā mahana ma mua o 300º C (572º F) a i ʻole nā mahana haʻahaʻa loa.

Nā Papa Hana Wela a me nā ʻokoʻa hana: ʻO ka hiʻohiʻona ʻokoʻa o17-4PHʻo ia kona maʻalahi o ka hoʻoponopono ʻana i nā pae ikaika ma o nā ʻano like ʻole o nā kaʻina hana mālama wela. ʻO ka hoʻololi ʻana i ka martensite a me ka paʻakikī ʻana o ka ua ʻelemakule ke ala nui o ka hoʻoikaika ʻana. ʻO nā papa mālama wela maʻamau i ka mākeke e komo pū me H1150D, H1150, H1025, a me H900.Kuhikuhi kekahi mau mea kūʻai aku i ka pono no ka mea 17-4PH i ka wā kūʻai, e pono ai ka mālama wela. Ma muli o ke ʻano like ʻole o nā pae mālama wela, pono e hoʻokaʻawale pono ʻia nā kūlana hoʻohana like ʻole a me nā koi hopena. ʻO ka mālama wela o 17-4PH e pili ana i ʻelua mau ʻanuʻu: ka mālama ʻana i ka hopena a me ka ʻelemakule ʻana. Ua like ka mahana o ka mālama ʻana i ka hopena no ka hoʻomaʻalili wikiwiki ʻana, a hoʻoponopono ka ʻelemakule i ka mahana a me ka helu o nā pōʻaiapuni ʻelemakule e pili ana i ka ikaika e pono ai.
Nā noi:
Ma muli o kona mau waiwai mechanical a me ke kūpaʻa i ka palaho maikaʻi loa, hoʻohana nui ʻia ʻo 17-4PH i nā ʻoihana e like me ka petrochemicals, ka mana nukelea, ka aerospace, ka pūʻali koa, ka moana, ke kaʻa, a me nā kahua lapaʻau. I ka wā e hiki mai ana, manaʻo ʻia he ʻano mākeke hoʻohiki e like me ke kila duplex.
