SO6621-3 igabanya ibikoresho byimpeta ya piston mubice bitandatu: icyuma cyumuhondo cyumuhondo, icyuma gikoreshwa nubushyuhe bwicyuma, icyuma cya karbide, icyuma cyoroshye, icyuma cyangiza, nicyuma. Muri 2012 Federal-Mogul yateguye urukurikirane rwa karindwi rwibikoresho bya piston, GOE70. Ibikoresho bifashisha matrix ya martensite hamwe na karubide ya chromium, irwanya kunama.

Ibikoresho nimero zikurikirana zikoreshwa muri sosiyete yacu:
Inomero y'ibikoresho: H9 (GOE13)
Numero yibikoresho: H6 (GOE32 F14)
Numero yibikoresho: H11 (GOE52 KV1)
Umubare wibikoresho: H11A (PVD piston impeta yibanze)
Numero yibikoresho: H12 (GOE56 KV4)
Numero yibikoresho: H17 (GOE65C SMX70 ASL813)
Numero yibikoresho: H18 (GOE66 SMX90 ASL817)
