Carbon Steel Valve Materials

Carbon and low-temperature carbon steels are the workhorse valve body materials for hydrocarbons, steam and non-corrosive utilities. They offer the best strength-to-cost ratio but have limited corrosion resistance and require impact-tested low-temperature grades (LCC, LF2) below -29C.

When do you use carbon steel valve materials?

Carbon and low-temperature carbon steels are the workhorse valve body materials for hydrocarbons, steam and non-corrosive utilities. They offer the best strength-to-cost ratio but have limited corrosion resistance and require impact-tested low-temperature grades (LCC, LF2) below -29C. This family includes 6 grades in our material library, listed below with their service-temperature limits and common designations.
