Key Features
1. High Simba uye Kuoma: 17-4 PH inogona kuwana kusimba kwakanyanya uye kuoma kuburikidza nekunaya-kuomesa kurapwa, zvichiita kuti ive yakakodzera kune maapplication anoda simba rakawanda.
2. Good Corrosion Resistance: Kunyangwe isingaite corrosion-resistant seaustenitic stainless steels senge 304 ne316, inoramba ichipa kunaka kwekusagadzikana munzvimbo zhinji.
3. Zvakanaka Weldability: Inogona kuve yakashongedzwa uchishandisa akasiyana welding maitiro. Post-weld heat treatment inokurudzirwa kuti iwane optimal properties.
4. Zvakanaka Machinability: Iyo ine yakanaka machinability mune yakagadziriswa-yakagadziriswa mamiriro uye inogona kuwedzera kuvandudza michina zvinhu mushure mekupisa kurapwa.
Mushure mekunaya kwakakodzera-kuomesa kupisa kurapwa, 17-4 PH simbi isina tsvina inogona kuzadzisa zvinotevera zvakajairwa zvemichina:
Tensile Simba: 930-1310 MPa (135-190 ksi)
Goho Simba: 725-1100 MPa (105-160 ksi)
Elongation: 10-20%
Kuderedzwa kweNzvimbo: 40-60%
Kuoma: HRC 28-38

Applications
Nekuda kwekubatanidzwa kwayo kwezvivakwa, 17-4 PH simbi isina tsvina inoshandiswa zvakanyanya mundima dzinotevera:
Aerospace Industry: Zvikamu zvakaita se turbine zvikamu, zvimiro zvikamu, nezvimwe.
Chemical uye Petrochemical Indasitiri: Zvinhu zvakadai semidziyo yemaitiro, mavharuvhu, pombi, nezvimwe.
Zvishandiso Zvekurapa: Zvishandiso zvakaita semidziyo yekuvhiya, midziyo yemazino, nezvimwe.
Power Generation: Zvikamu zvenyukireya reactor, pakati pezvimwe.
Zvokudya Zvokugadzira Zvokudya: Zvikamu zvemichina yemitsara yekugadzira chikafu.
