Ukwethulwa Kwensimbi Engagqwali engu-17-4ph

I-17-4 insimbi engagqwali (630) iyimvula ye-chromium-copper eqinisa izinto zensimbi engagqwali esetshenziselwa izinhlelo zokusebenza ezidinga amandla aphezulu kanye nezinga elilinganiselwe lokumelana nokugqwala.Amandla aphezulu
igcinwe cishe ku-600 degrees Fahrenheit (316 degrees
Celsius).

Izakhiwo Ezijwayelekile

Insimbi engagqwali Ingxubevange 17-4 PH iyimvula eyenza lukhuni insimbi engagqwali ye-martensitic enezengezo ze-Cu kanye ne-Nb/Cb.Ibanga lihlanganisa amandla aphezulu, ubulukhuni (kufika ku-572°F / 300°C), nokugqwala
ukumelana.

Ukumelana Nokugqwala

Ingxubevange engu-17-4 PH imelana nokuhlasela okulimazayo kangcono kunanoma yiziphi izinsimbi ezingenasici eziqinile eziqinile futhi iqhathaniswa ne-Alloy 304 kumidiya eminingi.

Uma kukhona izingozi ezingaba khona zokuqhekeka kokugqwala kwengcindezi, amazinga okushisa aphezulu okuguga kufanele akhethwe ngaphezu kuka-1022°F (550°C), okungcono kakhulu ku-1094°F (590°C).I-1022°F (550°C) izinga lokushisa elisezingeni eliphezulu kumidiya ye-chloride.

I-1094°F (590°C) izinga lokushisa eliphezulu elisezingeni eliphezulu kumidiya ye-H2S.

Ingxubevange ingaphansi kokuqhekeka noma ukuhlaselwa komgodi uma ichayeke emanzini olwandle amile nganoma yisiphi ubude besikhathi.

Iyakwazi ukumelana nokugqwala kwezinye izimboni zamakhemikhali, zikaphethiloli, zamaphepha, zobisi nezokulungisa ukudla (okulingana nebanga lama-304L).
