Selecting Materials

This information is intended to help make general comparisons between different available 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 304 is a low-carbon chromium-nickel stainless steel. Type 316 is 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-pressure 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.
