Product Description
Docol 500LA High Strength Low Alloy Steel (HSLA) Description
HSLA (High Strength Low Alloy) steel is a kind of steel material that increases the strength and toughness of steel by adding a small amount of alloying elements. HSLA steel is widely used in the world, especially in construction, bridges, automobiles, ships and other engineering fields. The production process of HSLA steel mainly includes hot rolling, cold rolling, heat treatment and welding. Hot rolling and cold rolling are the main ways to produce Docol 500LA HSLA steel. By rolling, the shape and size of the steel can be changed. The heat treatment process plays a crucial role in the properties of HSLA steel. The heat treatment process of quenching and tempering are usually used to obtain the best strength and toughness. Welding is an essential step of Docol 500LA HSLA steel in practical application to form a variety of complex structures and shapes.
