Q960D yog ib hom tempered high-strength steel, uas yog siv los tsim lub plhaub qhov chaw siab, cov khoom siv hluav taws xob siab, ntau yam tshuab engineering, xws li drilling rigs, hluav taws xob shovels, hluav taws xob log tsheb thauj khoom, mining tsheb, excavators, loaders, bulldozers, txhua yam ntawm cranes, hydraulic txhawb rau thee mines thiab lwm yam khoom siv kho tshuab, nrog rau cov khoom siv hluav taws xob tsis zoo ntawm cov mines thiab txhua yam kev tsim kho engineering.
Kev txheeb xyuas tshuaj muaj pes tsawg leeg ntawm Q960D steel phaj:
| C | Si | Mn | P | S | Ni | Cr | Mo | Cu | Nb | V | Ti | B | Sib Max |
| Tsawg dua los yog sib npaug rau 0.2 | Tsawg dua lossis sib npaug rau 0.8 | Tsawg dua los yog sib npaug 2 | Tsawg dua lossis sib npaug rau 0.025 | Tsawg dua lossis sib npaug rau 0.015 | Tsawg dua los yog sib npaug 2 | Tsawg dua los yog sib npaug li 1.5 | Tsawg dua lossis sib npaug rau 0.7 | Tsawg dua lossis sib npaug rau 0.5 | Tsawg dua lossis sib npaug rau 0.06 | Tsawg dua lossis sib npaug rau 0.12 | Tsawg dua lossis sib npaug rau 0.05 | Tsawg dua lossis sib npaug rau 0.005 | Tsawg dua lossis sib npaug rau 0.82 |
Cov lus hais: tsawg kawg ib qho khoom ua kom zoo ntawm Nb, Ti, V thiab Al yuav tsum muab ntxiv rau cov hlau, thiab qhov tsawg kawg nkaus ntawm yam tsawg kawg yog ib lub ntsiab yog {{0}}}.015 (ALS rau Al) . Alt tuaj yeem siv los hloov Als, lub sijhawm no Alt Ntau dua lossis sib npaug rau 0.018. CEQ=C + Mn / 6 + (Cr + Mo + V) / 5 + (Ni + Cu) / 15
