Ukwaziswa kwentsimbi ye-17-4PH

I-17-4 ipleyiti yentsimbi engenasimo (i-630) yi-chiromium-coperication eyonza nzima izinto ezingenasinyithi ezisetyenziselwa izicelo ezifuna amandla aphezulu kunye nenqanaba eliphakathi lokunganyangeki. Amandla aphezulu
igcinwe malunga ne-600 degrees fahrees (i-316 degrees
Celsius).

Iipropathi ngokubanzi

I-Stainis Steel Alloty 17-4 ph kukukhanya kwe-martication martiericic engenanqwayili kunye ne-cu kunye ne-NB / CB. Ibakala lidibanisa amandla aphezulu, ubunzima (ukuya kuthi ga kwi-572 ° F / 300 ° C), kunye ne-corrosion
Ukuxhathisa.

Ukunganyangeki

I-Allous 17-4 ph iyandihlasela ngokuhlaselwa kakhulu kunazo naziphi na izinto ezinobungozi ezingenamandla kwaye zithelekiswa ne-Alloty 304 kwimithombo yeendaba.

Ukuba kukho umngcipheko wokungabikho koxinzelelo lokuqhekeka, amaqondo obushushu aphezulu akhulileyo kufuneka akhethwe ngaphezulu kwe-1022 ° F (550 ° C), ngokukhethekileyo i-1094 ° F (590 ° C). I-1022 ° F (i-550 ° C) yiqondo elifanelekileyo lobushushu kwi-chloride yeendaba.

I-1094 ° F (590 ° C) yiqondo elipheleleyo lobushushu kwimithombo yeendaba ye-H2S.

I-Alloty ixhomekeke kwi-rivce okanye i-pitity yokuhlaselwa ukuba iboniswe kumanzi olwandle awomileyo ngalo naliphi na ixesha elide.

Yintonga enganyangekiyo kwikhemikhali, ipetroleum, iphepha, amashishini obisi kunye nokutya kunye nokutya (ukufana neBanga le-304l).
