The typical impact toughness of the joint for all
Strenx grades can also have a value of at least
27 J measured at -40°C and, in many cases, they
are considerably higher.

Table 2.2: The Strenx grades can be ordered with the displayed
minimum yield strengths. Strenx 700, Strenx 900 and Strenx 960
with plate thicknesses above 53.0 mm have slightly lower min yield
strengths than the diagram illustrates. The data sheet for each
steel grade gives more information in this respect.
