Hardness Ratings

Overlay Thickness BOROTUFFâ„¢ (HRC) CHROMOTUFFâ„¢ (HRC)
4.0 mm 57 – 61 57 – 60
8.0 mm 58 – 62 59 – 63

Microstructure Analysis

Phase Type BOROTUFFâ„¢ (%) CHROMOTUFFâ„¢ (%)
Primary Chromium Carbides 35 – 40 40 – 44
Eutectic Carbides 20 – 28 22 – 26
Martensite 14 – 20 10 – 14
Austenite 12 – 16 20 – 25

These plates feature a dense microstructure combining hard carbides embedded in an austenitic/martensitic matrix — ideal for extreme wear conditions.
