15Mo3 Pipes are alloy steel pipes primarily made up of carbon, manganese, molybdenum, and silicon, which give them remarkable mechanical and thermal properties. The typical chemical makeup includes about 0.12–0.20% carbon, 0.40–0.90% manganese, and 0.25–0.35% molybdenum. These components contribute to their impressive strength and resistance to oxidation and corrosion, especially at high temperatures. In terms of mechanical properties, 15Mo3 Pipes boast a tensile strength of around 440–590 MPa and good creep resistance, making them suitable for long-term exposure to high heat and pressure.
