Below is the typical chemical composition for custom (carbonsteel) flanges manufactured to the ASTMA105 specification. Custom flanges in lowpressure piping systems are most often made from this grade:
Element | ASTMA105 (%wt) |
---|---|
Carbon (C) | 0.35 |
Manganese (Mn) | 0.601.05 |
Phosphorus (P) | 0.035 |
Sulfur (S) | 0.040 |
Silicon (Si) | 0.100.35 |
Copper (Cu) | 0.40 |
Nickel (Ni) | 0.40 |
Chromium (Cr) | 0.30 |
Molybdenum (Mo) | 0.12 |
Vanadium (V) | 0.08 |
Iron (Fe) | Balance |
Key Points:
ASTMA105 is the standard for carbonsteel forgings used in piping components (flanges, fittings, valves) for ambient and elevatedtemperature service
Trace elements (Cu, Ni, Cr, Mo, V) are strictly limited to ensure weldability and toughness, while the bulk is iron and manganese with controlled carbon for strength and machinability.
