High carbon steels are those containing 0.45% carbon or higher. They are typically considered “hard to weld” because they are crack sensitive and are susceptible to undergoing significant changes in their physical and mechanical properties after welding.  However, high carbon steels can be welded successfully and without problems by having a sound understanding of the […]
