... ). This is not a hard and fast rule, because some steels with alloying slightly above 8% are sometimes referred to as “medium-alloy” steels. High-alloy steels typically refer to stainless steels, maraging steels, austenitic manganese steels, and some ultrahigh-strength nickel steels. High-Strength Low-Alloy (HSLA...
