The steels range in yield point or yield strength from 30 to 180 ksi (207 to 1241 MN/m2) and are available in a wide range of plate thickness; some are also available as structural shapes, pipe, and forgings. These steels have been developed not just because of a demand for versatility in strength, but because of a demand for steels with
