17-4PH 630 Birta Aan-Aamiga ahayn
Sharaxaad Gaaban:
Saky Steel's 17-4PH / 630 / 1.4542 waa mid ka mid ah kuwa ugu caansan uguna caansan birta birta ah ee chromium-nickel alloy ee leh wax lagu daro naxaas, roobkuna wuxuu ku qallafsan yahay qaab-dhismeedka martensitic. Waxaa lagu gartaa caabbinta daxalka sare iyadoo la ilaalinayo sifooyinka xoogga sare, oo ay ku jiraan adkaanta. Birtu waxay ku shaqayn kartaa inta u dhaxaysa -29 ℃ ilaa 343 ℃, iyada oo la ilaalinayo cabbirro aad u wanaagsan. Intaa waxaa dheer, qalabka fasalkaan waxaa lagu gartaa ductility yara wanaagsan iyo iska caabbinta daxalka waxay la mid tahay 1.4301 / X5CrNi18-10.
17-4PH, oo sidoo kale loo yaqaan UNS S17400, waa bir aan lahayn oo adkeynaysa roobab martensitic ah. Waa walxo badan oo si weyn looga isticmaalo warshadaha kala duwan, sida hawada hawada, nukliyeerka, petrochemical, iyo habaynta cuntada.
17-4PH waxay leedahay xoog sare, iska caabin daxalka wanaagsan, iyo engegan wanaagsan marka loo eego biraha kale ee aan nadiifka ahayn. Waa isku dhafka 17% chromium, 4% nikkel, 4% copper, iyo qadar yar oo molybdenum iyo niobium ah. Isku darka walxahan ayaa siinaya birta sifooyinkeeda gaarka ah.
Guud ahaan, 17-4PH waa walax aad u wanagsan oo faa'iido leh oo bixisa dheelitirnaan wanaagsan oo alaabooyin kala duwan ah.
