Steel castings are ideal for parts that endure
wear, shocks or heavy loads. Stronger than wrought iron, cast iron
and malleable iron, steel castings are very tough.
Special alloy elements are added to alloy steel castings to obtain
or increase certain desirable properties. Heat treating will also
improve ease of machining, increase wear resistance and remove
hydrogen trapped at the surface of the casting. The experienced
professionals at Carson Castings can answer all of your questions
regarding the strength and durability of steel castings.
Carbon steel castings are designated as:
Low carbon contains less than .20 percent
carbon, with tensile strength (annealed) from 40,000 to 70,000
Medium carbon contains .20 to .50 percent
carbon, with tensile strength (annealed) from 65,000 to 105,000
High carbon contains .50 percent carbon, with
tensile strength (annealed) from 95,000 to 125,000 psi.
Stainless steel castings resist atmospheric
corrosion, the attachment of hot or cold acids, and scaling at
elevated temperatures. Stainless steel castings can be designed
to resist corrosion and high temperature oxidation. Another
application of stainless steel is where unusual mechanical
properties of hardness, strength, toughness or ductility are
required, including resistance to wear and abrasion.
