15Mo3 is a low-alloy steel celebrated for its ability to withstand high temperatures and pressure. Its typical chemical makeup consists of around 0.12–0.20% Carbon, 0.90–1.20% Manganese, 0.25–0.35% Molybdenum, along with trace amounts of Silicon, Phosphorus, and Sulfur. The mechanical characteristics of 15Mo3 pipes include a tensile strength ranging from 440–590 MPa, a yield strength of at least 290 MPa, and impressive elongation of at least 22%. These attributes make 15Mo3 ideal for environments that experience high heat and pressure, providing excellent weldability, a long service life, and resistance to oxidation and corrosion.

15Mo3 pipes are extensively used in high-temperature and high-pressure settings due to their remarkable mechanical and thermal properties. They are mainly employed in the production of boilers, pressure vessels, and heat exchangers in power plants and industrial processing facilities. Additionally, these pipes are well-suited for petrochemical applications, oil and gas refineries, and chemical plants where high-temperature fluids or gases need to be transported. Thanks to their durability and resistance to thermal stress and corrosion, 15Mo3 pipes are perfect for critical systems that require long-term stability and reliability. Their weldability and performance make them a favored choice across various heavy industries.
