Unpacking ASTM A335 P5: The “Chrome Moly” Advantage
ASTM A335 P5 specifies seamless ferritic alloy-steel tubes for high-temperature service. The “Chrome Moly” name comes from its chemical composition.
Chromium (Cr) enhances oxidation resistance and boosts tensile strength, yield strength, and hardness at room temperature.
Molybdenum (Mo) improves high-temperature strength, wear resistance, and creep performance, while also inhibiting pitting corrosion.
These elements allow P5 alloy steel pipe to withstand harsh environments and mechanical stress.
