I-17-4PH I-ANNEALED STAINLESS

I-alloy 17-4 i-chromium-copper precipitation iqinisa isinyithi esingenasici esisetyenziselwa izicelo ezifuna amandla aphezulu kunye nenqanaba eliphakathi lokumelana nokubola. Lelinye lawona mabanga asetyenziswa kakhulu imvula eyenza lukhuni, njengoko inamandla aphezulu okuqina ukuya kuthi ga kwi-572 ° F ngelixa ibonisa ukuxhathisa okulungileyo kokuhlwa kuzo zonke iimeko zokuphathwa kobushushu. I-alloy 17-4 inokumelana okwaneleyo kwi-corrosion ye-atmospheric okanye kwiityuwa ze-asidi ezixutywe apho ukuxhathisa kwayo kufana ne-Alloy 304 okanye 430. I-alloy 17-4 inokuphathwa ubushushu kwiintlobo ezahlukeneyo zokushisa ukuphuhlisa uluhlu olubanzi lweepropati. Iimpawu zayo zomatshini zinokulungiswa ngonyango lobushushu apho amandla esivuno esiphezulu kakhulu ukuya kuthi ga kwi-180 ksi inokufezekiswa. I-alloy 17-4 ayifanele isetyenziswe kumaqondo okushisa angaphezu kwe-572 ° F okanye kumaqondo aphantsi kakhulu.

17-4 Intsimbi yentsimbi
Le mvula ye-martensitic eyenza lukhuni intsimbi engenasici inendibaniselwano yokuqina okuphezulu kunye nokomelela emva konyango olufanelekileyo lobushushu. Ikwanayo nokugqwala nokuxhathisa ubushushu okufanayo kwiBakala 304. Amagama amabini "Type 630" kunye "17-4PH" abhekisa kwibakala elinye.
