Gacanta birta chromium ee sare ee birta chromium ee la shubay waxaa laga sameeyay bir chromium oo sare ah oo ah walxo matrix ah, iyada oo loo marayo hab gaar ah, bir chromium oo sare iyo walxo malab ah oo dhoobada malab ah oo la shubay, walxo dhoobada ah oo dhoobada ah oo ZTA ah, ka dibna iyada oo loo marayo habka shubista ciidda, isku-darka dhoobada ee birta chromium ee sare iyo qaabaynta birta ductile ee labaad.
Halabuurka kiimikada ee walxaha birta ah ee chromium-ka badan waxaa lagu muujiyay Shaxda 1 ee hoose.
Shaxda 1: Halabuurka kiimikada ee duubista birta chromium-ka ee sare (wt%)
| Alaab | C | Si | Mn | S | P | Cr |
| Taayirada duubista ee isku-dhafka dhoobada ah ee birta chromium sare leh | 2.8-3.2 | 0.5-1.0 | 0.5-1.2 | ≤0.05 | ≤0.05 | 20-26 |
| Birta Ductile | 3.2-3.9 | 2.5-2.7 | 0.3~0.5 | ≤0.04 | ≤0.04 |
