17-4 PH Imvula Ukwenza Ukusakaza Kwensimbi Engagqwali kube lukhuni

17-4 PH Ukuzinza Ukwenza lukhuni Ukusakaza Kwensimbi Engenasici Isithombe Esifakiwe
  • 17-4 PH Imvula Ukwenza Ukusakaza Kwensimbi Engagqwali kube lukhuni
  • 17-4 PH Imvula Ukwenza Ukusakaza Kwensimbi Engagqwali kube lukhuni
  • 17-4 PH Imvula Ukwenza Ukusakaza Kwensimbi Engagqwali kube lukhuni

Incazelo emfushane:

Okubalulekile: 17-4 PH izulu eliqinisa insimbi engagqwali

Inqubo Yokukhiqiza: Ukuncibilika kanye Nokusakaza, Ukusebenza Okushisayo, Ukuhlanganisa Isixazululo, Umshini

Isicelo: Aerospace, Medical Devices, Marine

Ukuhlolwa Okutholakalayo: Ukuhlolwa Komshini, Ukuhlola I-Tensile, Ukuhlolwa Kokuqina, i-NDT

 

17-4 PHiyi-martensitic eqinisa izuluinsimbi engagqwali. Yaziwa ngamandla ayo aphezulu, ubulukhuni, kanye nokumelana nokugqwala okuhle kakhulu.

Izici Eziyinhloko

1. Amandla Aphezulu Nokuqina: 17-4 PH ingafinyelela amandla aphezulu kakhulu nobulukhuni ngokwelashwa okuqinisa imvula, iyenze ifanele izinhlelo zokusebenza ezidinga amandla aphezulu.

2. Ukumelana Nokugqwala Okuhle: Nakuba ingamelani nokugqwala njengezinsimbi ezingenasici ze-austenitic ezifana no-304 no-316, isanikeza ukumelana nokugqwala okuhle ezindaweni eziningi.

3. Ukushisela Okuhle:  Kungenziwa ashiselwe usebenzisa izinqubo ezahlukene Welding. Ukwelashwa kokushisa kwe-post-weld kunconywa ukuze kuzuzwe izakhiwo ezifanele.

4. Ukusebenza Okuhle: Inokusebenza okuhle esimweni esilashwe ngesixazululo futhi ingaqhubeka nokuthuthukisa izakhiwo zemishini ngemva kokwelashwa kokushisa.

Izinhlelo zokusebenza

Ngenxa yokuhlanganiswa kwayo kwezakhiwo, i-17-4 PH insimbi engagqwali isetshenziswa kabanzi kule mikhakha elandelayo:

Imboni ye-Aerospace: Izingxenye ezifana nezingxenye ze-turbine, izingxenye zesakhiwo, njll.

Imboni yeKhemikhali nePetrochemical: Izinto ezifana nemikhumbi yokusabela, ama-valve, amaphampu, njll.

Amadivayisi Ezokwelapha: Amathuluzi afana namathuluzi okuhlinza, amazinyo, njll.

Ukukhiqiza Amandla: Izingxenye zama-reactors enuzi, phakathi kokunye.

Izinsiza Zokucubungula Ukudla: Izingxenye zemishini yemigqa yokukhiqiza ukudla.
