1. The testing ambient room temperature.
2. 1MPa=1 N/mm2
3. “+N” means: Normalizing; +QT or +QT1 or +QT2 means: Quenching(air or liquid) and Tempering.
4. The Yield strength values at room temperature to 0.2% proof strength.
5. The value for Reduction are not relevant for acceptance.
6. Inspact determined from three individual values in each case.
