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.
| Grade (ASTM) | Common Name | Form | Min °C | Max °C |
|---|---|---|---|---|
| ASTM A216 WCB | Carbon Steel WCB | cast | -29 | +538 |
| ASTM A105 | Forged Carbon Steel A105 | forged | -29 | +538 |
| ASTM A216 WCC | Carbon Steel WCC | cast | -29 | +538 |
| ASTM A352 Grade LCC | Low Temperature Carbon Steel LCC | cast | -46 | +345 |
| ASTM A350 Grade LF2 | Low Temperature Forged Carbon Steel LF2 | forged | -46 | +345 |
| ASTM A352 LCB | Low Temperature Carbon Steel LCB | cast | -46 | +343 |
