Abstract

Prior third generation advanced high strength steels can produce ingots and hot bands that have a tendency to develop cracks. It has been found that an addition to third generation advanced high strength steels of one or more of molybdenum in an amount up to 0.50 wt % and nickel in an amount up to 1.5 wt %, eliminates the cracks in ingots, and improves the appearance of hot bands. More specifically the new exemplary alloys have shown to improve the toughness of ingots, as well as hot bands.
