The calcium - treatment of En 16 steel and its effect on fatigue properties (TM-MET-025)

In the B.S.C. Technical Note C/R/5/77 the possible beneficial effects on inclusion morphology, machinability and mechanical properties of the addition of calcium in an alloyed form to molten steel are discussed. Calcium affects the inclusion morphology in a variety of ways. Firstly the Type II MnS morphology (thin films or...
