17-4PH I-ANNEALED STAINLESS Steel

Ingxubevange 17-4 iyimvula ye-chromium-copper eyenza lukhuni insimbi engagqwali esetshenziselwa izinhlelo zokusebenza ezidinga amandla aphezulu kanye nezinga elimaphakathi lokumelana nokugqwala. Ingelinye lamabanga aqinisa imvula asetshenziswa kakhulu, njengoba linobunzima obuphezulu obufika cishe ku-572°F kuyilapho libonisa ukumelana nokugqwala okuhle kuzo zonke izimo eziphathwa ngokushisa. I-alloy 17-4 inokumelana okwanele kokugqwala komkhathi noma kusawoti we-asidi ehlanjululwe lapho ukumelana kwayo nokugqwala kulingana ne-Alloy 304 noma 430. I-alloy 17-4 ingaphathwa ngokushisa emazingeni okushisa ahlukahlukene ukuze kuthuthukiswe ububanzi bezakhiwo. Izakhiwo zayo zemishini zingenziwa kahle ngokwelashwa kokushisa lapho amandla esivuno esiphezulu kakhulu afinyelela ku-180 ksi angafinyelelwa. I-alloy 17-4 akufanele isetshenziswe emazingeni okushisa angaphezu kuka-572 ° F noma emazingeni okushisa aphansi kakhulu.

17-4 Insimbi Engagqwali
Le mvula ye-martensitic eyenza lukhuni insimbi engagqwali inenhlanganisela yobulukhuni obuphezulu namandla ngemva kokwelashwa okushisa okufanele. Futhi inokugqwala okufanayo nokumelana nokushisa kwe- Grade 304. Amagama amabili "Uhlobo 630" kanye "no-17-4PH" abhekisela ebangeni elifanayo.
