Mugihe atari ibisanzwe mubyuma byose bya karubone, ubushyuhe bwa kirogenike (kuvura sub-zeru kuri $ -300 ^ {\ umuzenguruko} F $) bikoreshwa mubutaka bwa karubone nyinshi nka SAE 1070 kugirango hahindurwe byimazeyo austenite yagumishijwe kuri martensite. Kubisoko byamazi bikoreshwa mumapompo yinganda zishobora guhura nubushyuhe bwumuriro, austenite yagumanye nikibazo kuko idahindagurika kandi irashobora guhinduka martensite mugihe cyangwa mukibazo, bigatera imikurire yimiterere nimpinduka mugihe cyimpeshyi. Mugushira mubikorwa uruziga rukurikira kuzimya ibanze, microstructure irahagaze. Ibi bivamo kunoza imyambarire no guhagarara neza, kwemeza ko preload kuri kashe ya pompe ikomeza guhoraho mubuzima bwibigize.
