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 groups low alloy steels and high alloy steels. The difference between the two is disputed.

High-strength low-alloy steel - Wikipedia

High-strength low-alloy steel (HSLA) is a type of alloy steel that provides better mechanical properties or greater resistance to corrosion than carbon steel.HSLA steels vary from other steels in that they are not made to meet a specific chemical composition but rather to specific mechanical properties.

Difference Between Alloy Steel and Carbon Steel ...

May 08, 2011 · Alloy steels are divided into low alloy steels and high alloy steels. When the percentage of added elements goes past 8 (in terms of weight), the steel is referred to as high alloy steel. In cases where added elements remain below 8% by weight of the steel, it is a low alloy steel. Low alloy steels are more common in the industry.
