What points should we pay attention to when welding high carbon steel
High carbon steel refers to carbon steel with w(C) higher than 0.6%. It has a greater tendency to harden than medium carbon steel and form high carbon martensite, which is more sensitive to the formation of cold cracks. At the same time, the martensite structure formed in the welding heat-affecte...Read more -
