Carbon & High Strength Low Alloy (HSLA) Bar
Carbon steel bar is defined as such, when no minimum chemical content is specified for aluminum, chromium, cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium, or zirconium, or any other element added to obtain a desired alloying effect.
High Strength Low Alloy (HSLA) steel bars consist of a group of steels with chemical compositions developed to maximize strength, ductility, weldability, and corrosion resistance. HSLA steels are produced with an emphasis on these properties rather than chemical composition limits. For this reason they are not considered alloy steels.
