About Custom Flanges

Below is the typical chemical composition for custom (carbon steel) flanges manufactured to the ASTMA105 specification. Custom flanges in low pressure piping systems are most often made from this grade:

Element	ASTMA105 (%wt)
Carbon (C)	0.35
Manganese (Mn)	0.60 1.05
Phosphorus (P)	0.035
Sulfur (S)	0.040
Silicon (Si)	0.10 0.35
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 carbon steel forgings used in piping components (flanges, fittings, valves) for ambient and elevated temperature 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.
