Tha allaidh fecral an seasamh làidir agus actadh dealain. Faodaidh Flefor Countress Countress Countress of 2192 gu 22828 F, a rèir teòthachd feart 2372F.
Gus leasachadh an aghaidh oxidation a leasachadh agus beatha obrach a mheudachadh, mar as trice bidh sinn a 'cur air falbh bho L + C, YTTRIM, HATRNIAM, Zirconium, msaa.
Mar as trice tha e air a chleachdadh ann am fùirneis dealain, hop glainne, teasadairean glainne quartz, luchd-teasairginn, inneal-catail catalytic, eileamaidean msaa.
0cr27AL7Mo2 mion-sgrùdadh ainmichte
27.00 CR, 7.00 al, 2.00 Mo, Bal. FE
Teòthachd obrach àrd-inbhe: 1400 C.
Tripiche uèir: 0.5 ~ 12mm
Teòthachd leaghaidh: 1520 c
Firstisity dealain: 1.53 Ohm MM2 / m
Chaidh a chleachdadh gu mòr mar eileamaidean teasachaidh ann an durgain gnìomhachais agus àthan dealain.
Chan eil nas lugha de neart as teotha na alloys tophet ach mòran àite leaghaidh nas àirde.
