Method B for the avoidance of hydrogen cracking in non-alloyed, fine grained and low alloy steels (developed by Dieter UWER and his co-Workers in Germany) Caution: CET generally not mentioned in Do. P CET to be computed from the product chemical analysis (need of 3. 1 or 3. 2 inspection document for proper computation)
