The plain carbon steels are explained in Mechanical Base. As you know, low alloy steels do not include alloying elements to improve the characteristics of steels. In low alloy steels, these alloying elements are added to improve the characteristics of steels. In this article, we will explain the low alloy steels, properties of the low alloy steels and alloying elements that are used in low alloy steels.
Low alloy steels include alloying elements up to 5% by weight. These percentages of alloying elements(except from carbon) in steels are the low alloy steels which means includes alloying elements at low amount.
Welding of these low alloy steels is vert troublesome. Low carbon steels can have very superior properties compared with plain carbon steels but the weldability is also a very important parameter. HSLA(High Strength Low Alloy Steels) steels are produced with much more lower alloy rates according to standards in low alloy steels without losing its weldability characteristics.
