Ukwethulwa kwensimbi engu-17-4ph

17-4 Iplate yensimbi engagqwali (630) i-chromium-zethusi ithukulo i-chromium-pericing ruding impahla yensimbi engagqwali esetshenziselwa izinhlelo zokusebenza ezidinga amandla aphezulu kanye nezinga elinganiselayo lokuphikiswa kokugqwala. Amandla aphezulu
kugcinwa cishe kuma-degree angama-600 angu-600 degrees
Celsius).

Izakhiwo Ezijwayelekile

I-alloy engenasici 17-4 PH iwukuhlukumezeka kwethanga lensimbi engenacala nge-CU ne-NB / CB. Ibanga lihlanganisa amandla aphezulu, lulukhuni (kuze kube ngu-572 ° F / 300 ° C), kanye nokugqwala
Ukumelana.

Ukumelana nokugqwala

I-Alloy 17-4 PH imelana nokuhlaselwa okulonakalisayo kangcono kunanoma iyiphi i-standard hardible cerless arvice futhi iqhathaniswa ne-Alloy 304 kwabezindaba eziningi.

Uma kunezingozi ezingaba khona zokuqhekeka kwengcindezi zokuqhekeka, amazinga okushisa aphezulu akhule azokhethwa ngaphezulu kwe-1022 ° F (550 ° C), mhlawumbe u-1094 ° C). I-1022 ° F (550 ° C) izinga lokushisa elimnandi ku-chloride media.

I-1094 ° F (590 ° C) izinga lokushisa elimnandi ku-H2S Media.

I-alloy ingaphansi kwe-crevice noma ukuhlaselwa okukhohlisayo uma kuvezwa ngamanzi asolwandle amile kunoma yibuphi ubude besikhathi.

Kuyinto emelana nokukhulisa kwamanye amakhemikhali, uphethiloli, ephepheni, ubisi nokudla kwezimboni (okulingana nebanga le-304L).
