Steel is considered to be low-alloy steel when either of the following conditions is met The maximum of the range given for the content of alloying elements exceeds one or more of the following limits 1.65 Mn 0.60 Si and 0.60 Cu Any definite range or definite minimum quantity of any of the following elements is specified or required within the limits of the recognized field of constructional alloy steels aluminum boron chromium up to 3.99 cobalt niobium molybdenum nickel titanium tungsten vanadium zirconium or any other alloying element added to obtain the desired alloying effect Alloying elements are added to hot-finished plates for various reasons including improved corrosion resistance and or improved mechanical properties at low or elevated temperatures. Alloying elements are also used to improve the hardenability of quenched and tempered plate. Low-alloy steels generally require additional care throughout their manufacture. They are more sensitive to thermal and mechanical operations the control of which is complicated by the varying effects of different chemical .
