ABSTRACT:
The incidence of rare earth oxy-sulfide inclusions in killed hot-rolled high strength low alloy steels of the vanadium-nitrogen type is lowered through restriction of the silicon content to 0.05% maximum without a concurrent reduction of yield strength to values below 80,000 p.s.i. through a balance of composition, product thickness and hot-rolling collection temperature.
