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 subjected to high heat and pressure, providing excellent weldability, a long service life, and resistance to oxidation and corrosion.
