Carbon Steel Investment Castings
There are several properties of carbon steel that make it a popular material for producing investment cast products. The material is cost-effective, readily available, strong, possesses good wear resistance, and is easily machined. For these reasons, several grades of carbon and low alloy steel are widely used. Are you looking for a partner who can manufacture carbon steel investment castings precisely to your specifications? Count on the experience and expertise of American Casting Company. Over the years we have produced a wide range of net-shape investment casting parts using low alloy and mild steel materials.
Mechanical Properties of Mild and Low Alloy Steel Investment Casting
The below table depicts the mechanical properties of mild (low carbon) steel.
Mild (Low Carbon) Steel
Alloy | Heat Treatment | UTS (kpsi) | YS (kpsi) | % Elongation | Hardness |
---|---|---|---|---|---|
1020 | Annealed | 55-60 | 35-40 | 25-35 | Rb 80 Max |
1020 Modified | Annealed | 85-100 | 60-65 | 10-15 | Rb 100 Max |
The below table depicts the mechanical properties of low alloy carbon steel.
