When steel with specialized properties is needed, low-alloy steel investment castings may be the best production option. Low-alloy steel is made by enhancing the steel with precise amounts of various ingredients, such as molybdenum for strength, silicon and manganese to limit oxidation, chromium for hardness, strength and oxidation resistance, and many others. These additives are typically 1% to 5% of the resulting steel’s content. Among the many uses for low-alloy steel are pipelines, shipbuilding, heavy equipment, structural steel, bridges, boilers, and numerous others.
