Selecting Materials
Material Features and Benefits
Stainless Steel
A corrosion-resistant material that provides high strength at high temperatures, helps prevent
contamination of product being transported, maintains cleanliness, and retains a lustrous
appearance. Harder then brass. Type 304is a low-carbon chromium-nickel stainless steel.Type
316is similar to type 304, but has a high nickel content as well as a molybdenum for stronger
resistance to heat and corrosion. Often used for water, oil, gas, and steam in low- to high-
pressure applications.
Brass
Has good corrosion resistance and is less expensive than stainless steel. Is softer and easier
to thread than stainless steel and forms tight seals. It can be used interchangeably with copper
where heavier walls are required. Found in plumbing and heating application. Also good with oil,
natural gas, and air. Resists corrosion from salt water as well as fresh water polluted with waste
from mineral acids and peaty soils. Use in low- to high-pressures applications.
Steel
Used in noncorrosive environments. This carbon- and iron-based metal is hard and strong. It is
an economical alternative to stainless steel and brass in high-pressure applications. For use with
water, oil, gas, and steam in low- to high-pressure applications where corrosion is not a problem.
