The weld metal in joints of the Strenx® performance steel 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® wear plate 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.
