Nā mea nui
1. Ka ikaika a me ka paakiki: Hiki i ka 17-4 PH ke hoʻokō i ka ikaika kiʻekiʻe a me ka paʻakikī ma o ka hoʻomaʻamaʻa ʻana i ka ua-paʻakikī, e kūpono ana i nā noi e koi ana i ka ikaika kiʻekiʻe.
2. Kū'ē Kū'ē maikaʻi: ʻOiai ʻaʻole like me ka corrosion-resistant e like me austenitic stainless steels e like me 304 a me 316, ke hāʻawi mau nei ia i ke kūpaʻa corrosion maikaʻi i ka hapa nui o nā kaiapuni.
3. Weldability maikaʻi: Hiki ke wili ʻia me ka hoʻohana ʻana i nā kaʻina hana welding. Manaʻo ʻia ka mālama wela ma hope o ka weld no ka loaʻa ʻana o nā waiwai maikaʻi loa.
4. Maikaʻi maikaʻi: Loaʻa iā ia ka machinability maikaʻi i ke kūlana i mālama ʻia a hiki ke hoʻomaikaʻi hou i nā waiwai mechanical ma hope o ka mālama ʻana i ka wela.
Ma hope o ka hoʻomaʻamaʻa ʻana i ka wela me ka paʻakikī o ka ua, hiki i ka 17-4 PH ke kila kila ke hoʻokō i nā ʻano mechanical maʻamau:
Ikaika U'i: 930-1310 MPa (135-190 ksi)
Ka ikaika hua: 725-1100 MPa (105-160 ksi)
ʻO ka elongation: 10-20%
Hoemi o Wahi: 40-60%
ʻoʻoleʻa: HRC 28-38

Nā noi
Ma muli o ka hui pū ʻana o nā waiwai, hoʻohana nui ʻia ka 17-4 PH stainless steel i nā kahua aʻe:
ʻOihana Aerospace: Nā ʻāpana e like me nā ʻāpana turbine, nā ʻāpana hana, etc.
ʻOihana Kimia a me Petrochemical: ʻO nā mea e like me nā moku hopena, nā valves, pumps, etc.
Na Lapaau Lapaau: ʻO nā mea hana e like me nā mea hana ʻokiʻoki, nā lako niho, etc.
Hoʻoulu mana: Nā ʻāpana no nā reactor nuklea, a me nā mea ʻē aʻe.
Lako Hana Mea ai: Nā ʻāpana mīkini no nā laina hana meaʻai.
