Investment casting is an industrial process based on and also called lost-wax casting, one of the oldest known metal-forming techniques.

The process is generally used for small castings, but has been used to produce complete aircraft door frames, steel castings of up to 300 kg (660 lbs) and aluminium castings of up to 30 kg (66 lbs). It is generally more expensive per unit than die casting or sand casting, but has lower equipment costs & pattern costs. It can produce complicated shapes that would be difficult or impossible with die casting, yet like that process, it requires little surface finishing and only minor machining.

Steel can be subdivided into carbon steel, low-carbon steel and high-carbon steel according to carbon content; steel also can be divided into hammered steel, cast steel, hot-rolled steel and cold drown steel according to different forming ways.

Steel casting manufacturers make cast steel or carbon steel as raw materials, use advanced casting technology, to produce cast steel products with good mechanical properties, and cast steel and carbon steel casting are widely applied in many industries.
