Table 3.
Normalised BMAT-T weight loss of reference alloys during the three 20 hr tests, calculated based on three different normalisation methods.
The two bottom rows show the average normalised weight loss and relative standard deviation (RSD) in the calculation of the average (in %).
| Spec No. | Bis500 – abrasion resistant steel |
CB100 – slightly hyper-eutectic high-Cr WCI |
CB123 – hypo-eutectic high-Cr WCI |
