961 Aviation Hniav Steel Bar

961 Aviation Blade Steel muaj cov khoom siv kho tshuab zoo heev thiab tau siv dav hauv kev lag luam aviation los tsim cov khoom tseem ceeb xws li cav hniav, discs, thiab shafts ua haujlwm hauv qab 600 degree.

Cov cuab yeej siv cua sov rau cov txheej txheem ua haujlwm kub ntawm 961 (1Cr11Ni2W2MoV) steel blades txais RJX-45-9 thiab RJX-75-13 muaj hluav taws xob furnaces. Ua ntej thauj cov ntaub ntawv raw rau hauv lub qhov cub, cov khoom txawv teb chaws hauv lub tshuab hluav taws xob yuav tsum tau muab tshem tawm kom huv si kom tsis txhob sib xyaw, thiab cov cuab yeej tswj qhov kub yuav tsum tau ntsuas raws li cov txheej txheem yuav tsum tau ua; Txhawm rau txhim kho qhov sib xws ntawm qhov kub thiab txias, cov kab hluav taws xob asbestos tuaj yeem siv rau cov qhov rooj rau qhov cub, nrog tus nqi zoo tshaj lossis sib npaug li 87 feem pua. 3, Kev tsim cov txheej txheem kub ua haujlwm tshwj xeeb rau aviation 961steel blades hauv cov txheej txheem kuaj yuav tsum ua raws li cov kev cai hauv HB5024-89 "Aviation Steel Forgings".
