What is the chemical composition of P5 material
Jan 06, 2026
P5 alloy seamless steel pipe is a type of chromium-molybdenum alloy steel, mainly composed of chromium (Cr) and molybdenum (Mo), with chromium content typically around 5% and molybdenum content around 0.5%. This composition gives it excellent high-temperature resistance and corrosion resistance. Compared to ordinary carbon steel, P5 alloy steel maintains higher strength and oxidation resistance even at high temperatures, making it highly favored in industries such as petrochemicals and power generation.
The specific values are as follows:
Carbon (C): ≤0.15%
Manganese (Mn): 0.30~0.60%
Phosphorus (P): ≤0.025%
Sulfur (S): ≤0.025%
Silicon (Si): ≤0.50%
Chromium (Cr): 4.0~6.0%
Molybdenum (Mo): 0.45~0.65%
