ASTM A335 Umuyoboro wa Alloy Umuyoboro

ASTM A335 Amashanyarazi Amashanyarazi adafite umuyoboro wihariye

Ibisobanuro bigufi:

ASTM A335 bakunze kwita umuyoboro wa chrome moly kubera imiti irimo Molybdenum (Mo) na Chromium (Cr).Molybdenum yongerera imbaraga ibyuma na Chromium (cyangwa chrome) nikintu cyingenzi kigizwe nicyuma.Ibigize chrome moly alloy umuyoboro wibyuma bituma biba byiza gukoreshwa mumashanyarazi, inganda, inganda zikomoka kuri peteroli, hamwe na serivise zamavuta aho amazi na gaze bitwarwa mubushyuhe bukabije hamwe nigitutu.

Kuvura Ubushuhe

Umuyoboro wa Alloy Steel ukoreshwa ubushyuhe kugirango ugere kumiterere yubukanishi ukurikije ikintu cyifuzwa.Hano hari bumwe muburyo bwo kuvura ubushyuhe.

Kora ibisanzwe no kuzimya.

Transvers / longitudinal: guhagarika umutima no gusibanganya, gukomera, kugerageza kugoreka- kubintu byakorewe ubushyuhe mu itanura ryicyiciro, ibi bizamini bizakorwa kuri 5% yimiyoboro iva kuri buri mubare wubushyuhe.Kubufindo buto, umuyoboro umwe byibuze ugomba kugeragezwa.

ASTM A335 Gr.P91 igomba kugira ubukana bwa 250 HB / 265 HV (25 HRC).
