This cleaner Vascojet-1000 is approximately two to three times tougher than the previous material tested here. The edge notched specimens gave a lower toughness value possibly because they had a sharper initial crack. The high oxygen content of the air melted Vasco X-3 may have been an embrittling agent as the toughness values of the X-3 were low. The microphotographs show typical inclusions present in the two steels.
