The difference is somewhat uniform, but to make it distinguishable, all steel alloyed with higher than 8% of its weight of elements other than carbon and alloy is considered high-alloy steel. Alloyed steels are harder, more durable and more resistant to corrosion. Alloy steels with carbon levels of medium to elevated rates are difficult to weld.
