Overview of types of steel produced at the Southwest Steel Casting Company.


Carbon Steel Castings
Carbon steel castings are designated as low, medium, and high carbon. Low carbon steel castings have a carbon content of less than .20 percent. Their tensile strength (annealed) ranges from 40,000 to 70,000 pounds per square inch.

Medium carbon steel castings have a carbon content from .20 to .50 percent. Their tensile strength (annealed) ranges from 65,000 to 105,000 pounds per square inch.

High carbon steel castings have a carbon content of more than .50 percent. Their tensile strength (annealed) ranges from 95,000 to 125,000 pounds per square inch.

Alloy Steel Castings
Alloy steel castings are those in which special alloy elements have been added in sufficient quantities to obtain or increase certain desirable properties. Their are two types of alloy steels- the low alloy steels with an alloy content totaling less than 8 percent and high alloy steels with their content totaling more than 8 percent.

Stainless Steel Castings
Stainless steel castings are designed to resist atmospheric corrosion, the attach of hot or cold acids, and scaling at elevated temperatures.

The applications of stainless steels may be divided into two groups. The first is where corrosion resistance is required, including resistance to high temperature oxidation. The second is where unusual mechanical properties of hardness, strength, toughness or ductility are required, including resistance to wear and abrasion.

Low Temperature Steel
Low temperature steel is designed for use in low temperature conditions and is tested for it's impact properties in minus degrees F. Typical applications are parts that are put into service in artic conditions in construction, petrochemical, and marine industries.
