Intshayelelo ye-17-4ph yeNtsimbi eNgatyiwayo

I-17-4 iplate yensimbi engenasici (i-630) i-chromium-copper precipitation iqinisa izinto zensimbi ezingenasici ezisetyenziselwa izicelo ezifuna amandla aphezulu kunye nenqanaba eliphakathi lokumelana nokubola.Amandla aphezulu
igcinwe ukuya kuthi ga kuma-600 degrees Fahrenheit (316 degrees
iCelsius).

Iipropati ngokuBanzi

Insimbi engenasici iAlloy 17-4 PH yimvula eqinisa intsimbi ye-martensitic ene-Cu kunye ne-Nb / Cb eyongeziweyo.Ibakala lidibanisa amandla aphezulu, ubulukhuni (ukuya kuthi ga kwi-572 ° F / 300 ° C), kunye nomhlwa.

Ukunyangwa kokuMhlwa

I-alloy 17-4 PH imelana nokuhlaselwa kwe-corrosion engcono kunayo nayiphi na i-standard hardenable steels stainless kwaye ifaniswa ne-Alloy 304 kumajelo amaninzi.

Ukuba kukho imingcipheko enokubakho yokuqhekeka koxinzelelo lwe-corrosion, amaqondo obushushu aphezulu aphezulu ke kufuneka akhethwe ngaphezulu kwe-1022 ° F (550 ° C), ngokukhethekayo 1094 ° F (590 ° C).I-1022 ° F (550 ° C) lelona qondo lobushushu liphezulu kwimidiya yechloride.

I-1094°F (590°C) lelona qondo lobushushu liphezulu kwimidiya ye-H2S.

Ingxubevange ixhomekeke kwimingxuma okanye uhlaselo lwemingxuma ukuba ibekwe kumanzi olwandle amileyo ngalo naliphi na ixesha elide.

Iyakwazi ukumelana ne-corrosion kwezinye iikhemikhali, i-petroleum, iphepha, imveliso yobisi kunye nemveliso yokutya (elingana ne-304L grade).
