The consumables with the appropriate strengths for welding the Hardox and Strenx grades can, in many cases, attain favorable toughness values in the all weld metal.
The weld metal in joints of the Strenx grades can reach an impact toughness – with many kinds of consumables – that is typically above the toughness requirements of the unaffected parent metal.
There are seldom exact, specified toughness requirements for joints in the Hardox grades. When measured, the impact toughness values in the weld metal are normally at a level of – or above – the typical impact toughness values for these steel grades.
