Tool Steel Investment Casting: Strength and Precision
Tool steel is ideal for investment castings operating in high-temperature, non-corrosive environments. Its alloy composition—including molybdenum, carbon, manganese, silicon, tungsten, and vanadium—ensures exceptional durability and heat resistance while maintaining structural integrity.
At China Metal Castings, we produce precision tool steel investment castings in grades such as A2, D2, O1, and more, with tight tolerances of ±0.005″ per inch. Our in-house secondary machining, heat treatment, and finishing services allow us to deliver components in various hardness levels—from fully annealed (RC 20) to hardened and tempered (up to RC 60)—ensuring optimal performance for your application.
