Our recommendations for Weldox high strength steel are based on typical values for toughness in the HAZ being<br />
at least 27 J at -40 °C. The dem<strong>and</strong>s on toughness in the weld joints in Hardox wear plate are often lower.<br />
The recommendations for Hardox should therefore be regarded as approximate values.<br />
When a joint comprising different plate thicknesses is welded, the recommended<br />
heat input is based on the thinnest plate in the welded joint.<br />

In this case, the permissible heat input is based<br />
on the 11 mm plate thickness.
