What are the disadvantages of low alloy steels?
A common disadvantage of carbon and low- alloy steels is their rather high temperature of ductile-to-brittle transition, below which the impact toughness of the steels becomes quite low, making the steels unsuitable as structural materials serving at lowered temperatures
