9SiCr kub dov steel puag ncig tuav

9 sicr steel yog tsawg alloy txiav hlau, tab sis kuj feem ntau ua rau txias ua hauj lwm pwm qhov chaw, cov nyhuv yog zoo heev. Nws dua li chrome steel (Cr2 lossis 9 Cr2) muaj zog dua thiab hardenability thiab muaj kev ruaj ntseg siab. Cov lus hais los ntawm cov qub Soviet Union thaum ntxov li 9 xc, ib zaug hu ua 9 crsi steel. Kev sib xyaw thiab kev ua haujlwm nrog 9 xc yog tib yam.
Tsawg thermal specification
Xav tau nyob rau hauv nruab nrab cua los yog tiv thaiv cua sov cua sov, preheating kub ntawm 700 ~ 80 ° C o thawj zaug, tuav lub sij hawm 1. 0 ~ 1.5 h, lub thib ob 850 ~ 900 ° C, 2 min / mm, lub sij hawm ntawm kev txuag hluav taws xob thaum tshav kub kub rwb thaiv tsev ntawm 100 ℃ los yog tsawg dua tom qab ceev txog 1100 ~ 1150 ℃, tuav lub sij hawm 1.0 ~ 1.5 min / mn. Yuav tsum nquag tig ntawm billet nyob rau hauv cov txheej txheem ntawm cua sov, uniform kub, tag nrho burned. Qhov kub ntawm forging 1050 ~ 1100 ° C, rov ua dua ob npaug rau qhov chim siab forging, tom qab forged alloy carbide qib 2 lossis tsawg dua.
