"The T23 and T24 steel were designed for welding membrane water walls without preheating and without PWHT. Our investigations concerning secondary hardening of steels containing vanadium show, that non-tempered welded joints undergo a significant increase in hardness during exposure at operating temperature. This process is accompanied by decreasing of impact toughness especially in heat affected zone (HAZ). It follows that Post Weld Heat Treatment (PWHT) of T23 and T24 welds is necessary"@en . .
