Machinable carbon and alloy steels prodn. - by deoxidation using two grades of calcium-silicon-aluminium alloys (HU 28.8.78)

摘要

In the prodn. of machinable plain carbon and alloy steels, deoxidation is carried out using two grades (A, B) of the ferroalloy Casual which contain 70-80wt.% Si and pref. 10-20 wt.% Mn. Grade (A) has a Ca.
