Fly foundry could manufacture carbon steel investment castings according to your requirements as well.Of course,carbon steel investment castings are investment castings with material carbon steel.Maybe you would ask what is carbon steel?Carbon steel is a steel containing carbon element less than 2.11% and no special alloy elements are added.Except carbon elements,there is also trace elements in it,like Mn,S,P.

Normally,Carbon steel is choose to make investment castings which have strong lade or stress demands to ensure mechanical properties.For stainless steel investment castings are used in the condition of corrosion.Carbon steel could be divided into low carbon steel(WC≤0.25%),middle carbon steel(WC 0.25%-0.6%) and high carbon steel(WC>0.6%) according to different carbon content.The higher carbon content is,the higher the hardness and strength will be.But the plasticity will be lower.

Fly foundry could supply carbon steel investment castings weights from 0.5kg to 100kg with lost wax casting process.Our annual capacity is about 5000t.The material specifications of common carbon steel investment castings like 20#,30#,45#,80#,ect.Below are the chemical composition of common carbon steel for your reference.
