Alloy steel Wikipedia

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groupslow alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%. Most commonly, the phrase "alloy steel"

High Strength Low Alloy Steel imoafo

High Strength Low Alloy (HSLA) Steel. Typically, Mo is used in HSLA steel when the yield strength must be above 550 MPa, or a particular microstructure is demanded. Mo is particularly beneficial for producing bainite (and more specifically for its acicular ferrite variant) and the multiphase microstructures that appear in dual phase, complex phase or TRIP steels.
