What is the role of sulfur in the EN 10083-3 50CrMO4 steel plate?

S is usually also a harmful element. It makes the EN10083-3 50CrMo4 steel plate hot brittle, and the EN10083-3 50CrMo4 steel plate has reduced ductility and toughness, and cracks occur during forging and rolling.
S is also detrimental to soldering performance and reduces corrosion resistance. Therefore, the sulfur content is usually less than 0.055, and the high quality EN10083-3 50CrMo4 steel plate is less than 0.040.
