Benefits of Steel Investment Castings
Steel investment castings are an inexpensive alternative to stainless steel castings. A metal casting is simply a piece of metal that started out as liquid metal. The metal is poured into a cast with the finished design of the desired part. Steel castings do not have the corrosion-resistant properties that stainless steel casings have, but they are much less expensive to manufacturer.
In general, the oil and gas industry, automotive industry, agriculture industry, and the valve and pump industry use steel investment castings the most. Other industries prefer the use of the more expensive stainless steel castings, or castings made from another type of metal, mainly because of the elimination of the possibility of rust and corrosion from harsh chemicals or other materials.
The steel parts can save a company that uses a large amount of investment casting parts a great deal of money. The lathe time for steel castings is less than that for parts made through other methods. Investment casting eliminates much of the scrap waste generated through other machining methods, such as die casting or metal tooling. With investment casting, it is easy to produce the precise right size and shape of part necessary for the job.
After the initial casting process, the parts can be altered and modified to fit unique specifications. Heat treating the metal will make it harder and more durable. With secondary annealing operations, a factory can transform hard steel into a material that is nearly as soft as aluminum, which is ideal for certain industrial uses.
For the most part, if a factory can use a part without the risk of contaminating the process with rust, using a steel casted part is one of the best and least expensive methods. Factories can save thousands of dollars each year by using the material that is free of expensive chrome and nickel in many different machine applications.
