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.
