4.Outstanding Toughness: Inochengetedza kutendeseka kwemaitiro kunyange pasi pekupisa kwakanyanya uye mamiriro ezvinhu akaoma.
Kurapa Kupisa uye Kunaya Kwemvura Kuoma
Chii chinosiyanisa 17-4 PH Stainless simbi ndiko kugona kwayo kunoshamisa kwekunaya kwemvura - maitiro ekurapa kupisa ayo anosimudzira zvakanyanya mashandiro ayo. Nekupisa alloy kune chaiyo tembiricha inoteverwa nekudzora kuchembera, zvimiro zvayo zvinogona kukwenenzverwa.Mamiriro ezvinhu akajairwa ekupisa anosanganisira:
• H900: Inopa masimba epamusoro-soro.
• H1150: Inopa kusimba kwepamusoro uye kuwedzera kuoma.
Uku kuchinjika kunoita kuti mainjiniya agadzirise hunhu hwezvinhu kuti zvisangane nezvinodiwa zveakasiyana maindasitiri ekushandisa.
Zvishandiso zve17-4 PH Stainless Simbi
Iwo epamusoro zvivakwa zve 17-4 PH simbi isina tsvina anoita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa:
• Aerospace: Inoshandiswa mumagungano ekugadzirisa, turbine components, uye high-performance fasteners.
• Munda Wezvokurapa: Yakanakira maturusi ekuvhiya nemazvo anogara akasimba.
• Chemical Processing: Inoshandiswa mumareactors uye midziyo inotsungirira kuratidzwa kwemakemikari zvine hukasha.
• Oiri & Gasi: Inowanikwa mupombi shafts, mavharuvhu, uye zvimwe zvikamu pasi pekumanikidzwa kwepamusoro uye corrosive media.
• Defence Sector: Inovimbwa nekugadzira zvinhu zvakasimba mugiredhi remauto.
Aya maapplication anosimbisa kuvimbika kwayo munzvimbo dzakaoma umo zvese simba uye hupenyu hurefu hwakakosha.
Sei Kusarudza 17-4 PH Stainless Simbi?
17-4 PH simbi isina tsvina inova mhinduro yakasarudzika kana zvikumbiro zvichidaidza:
• Inoshamisa mechanical simba kutsungirira mitoro inorema uye kushushikana.
• Kuramba kwakavimbika kwecorrosion munzvimbo dzine hukasha kana dzinoda.
• Flexible heat treatment options to fine-tune performance performance.
Kusimba kwayo kwakaratidza uye kuchinjika kunoita kuti ive sarudzo inovimbika kumaindasitiri anoda kushanda kwepamusoro, zvinhu zvinogara kwenguva refu.
Mhedziso
Kubatanidza simba repamusoro, kusimba kwekuora kwakanakisa, uye kuchinjika kunoshamisa, 17-4 PH simbi isina tsvina isarudzo yepamusoro-soro yekushandisa-yakakosha maapplication. Kana ichienzaniswa nemagiredhi akajairwa se304 ne316, inozvisiyanisa nekuvimbika kwakadzama pasi pemamiriro akaomarara. Kuwanikwa kwayo pamitengo yemakwikwi-kunyanya mumisika yakaita seIndia-kunowedzera kukwezva kwayo kwekushandisa kwakasiyana kwemaindasitiri, kuunza zvese kushanda uye kukosha.
