Ukunyamezela ubude: ukunyamezela ubude kuyo yonke imilinganiselo kubukhulu +5/-0 mm.
Ukucaba: max. I-4% (inkqubo yokulinganisa ngokusekelwe kwi-ASTM B760)
Uxinaniso: Ubukhulu <10.00mm Ubuninzi >19.2g/cm³
ubukhulu (10.00-20.00mm) ubukhulu = 19.1g/cm³
Ubunzima bukaVickers:
≤0.10 mm ≥550 HV
0.10-0.05 mm ≥500 HV
0.50-1.50mm ≥470 HV
1.50-10.00mm ≥450 HV
10.00-20.00mm ≥420 HV
Ukubonakala: Izinto eziphathekayo ziya kuba kumgangatho ofanayo, zikhululekile kwizinto zangaphandle, ukuhlukana kunye nokuphuka.
Ibhedi yebhedi (engalungiswanga) inokuba neentanda ezincinci zomphetho.
Umgangatho womphezulu:
Ukubanda kuqengqeleka ≤ 0.30mm eqaqambileyo
I-cold rolled i-0.3-0.5 mm ekhethiweyo
Ishushu iqengqeleke ≥0.50 mm echoliweyo
