Intshayelelo yentsimbi engagqwaliyo eyi-17-4ph

Ipleyiti yentsimbi engagqwaliyo engu-17-4 (630) sisixhobo sentsimbi engagqwaliyo esiqinileyo esisetyenziswa kwizicelo ezifuna amandla aphezulu kunye nokumelana nokugqwala okuphakathi. Amandla aphezulu
igcinwe ukuya kuthi ga kuma-degrees Fahrenheit angama-600 (316 degrees)
iCelsius).

Iipropati eziQhelekileyo

I-Alloy yentsimbi engagqwaliyo eyi-17-4 PH yintsimbi engagqwaliyo ye-martensitic eqinisa imvula ene-Cu kunye ne-Nb/Cb ezongeziweyo. Olu hlobo ludibanisa amandla aphezulu, ubulukhuni (ukuya kuthi ga kwi-572°F / 300°C), kunye nokugqwala.

Ukumelana nokugqwala

I-Alloy 17-4 PH imelana nokuhlaselwa yingqele ngcono kunayo nayiphi na intsimbi engagqwaliyo eqhelekileyo kwaye iyafana ne-Alloy 304 kwiindidi ezininzi zeendaba.

Ukuba kukho iingozi ezinokubakho zokuqhekeka koxinzelelo lokubola, amaqondo obushushu aphezulu okuguga kufuneka akhethwe ngaphezulu kwe-1022°F (550°C), kungcono i-1094°F (590°C). I-1022°F (550°C) lolona bushushu bokufudumeza obufanelekileyo kwi-chloride media.

I-1094°F (590°C) yeyona qondo lobushushu elifanelekileyo kwi-H2S media.

Ingxubevange ichaphazeleka yimingxuma okanye ihlaselwe yimingxuma ukuba ivezwe emanzini olwandle angashukumiyo ixesha elide.

Ayinakumelana nokugqwala kwezinye iikhemikhali, ipetroliyam, iphepha, imveliso yobisi kunye nokutya (ilingana nomgangatho we-304L).
