Battelle drop-weight tear test (BDWTT)*

The unique microstructure of toughcore® is characterized by extreme values of toughness even at very low temperatures, leading to an exceptional high ductile fraction ratio. A ductile fraction ratio of 85% down to -60 °C can be achieved with toughcore®, an advancement that increases safety levels in applications such as offshore platforms and penstocks.

*) Typical values for grade X80 in thickness 50 mm
