16Mo3 – Chrome-Moly Pressure Vessel Steel for Elevated Temperature Service 16Mo3 is a low-alloy pressure vessel steel with added molybdenum (0.3%), designed for use at elevated temperatures. It is widely used in applications where resistance to creep, heat, and oxidation is essential. With excellent thermal strength, fabrication properties, and cost-efficiency, 16Mo3 is commonly used in boilers, heat exchangers, and piping systems operating in harsh thermal environments. As per EN 10028-2 standards, 16Mo3 has become a go-to material across power generation, refineries, and petrochemical industries for mid-range temperature applications. Key Benefits: High Temperature Resistance: Designed for service temperatures up to ~600°C, maintaining good mechanical performance under thermal stress. Creep and Oxidation Resistance: Molybdenum addition enhances resistance to long-term heat-induced deformation and corrosion from hot gases and steam. Good Weldability and Fabrication: Suitable for standard welding processes with correct heat treatment; easily formed and machined for complex vessel construction. Reliable in Moderate Pressure Systems: Ideal for pressure equipment operating under both internal pressure and elevated temperature conditions. Mechanical Properties Overview: Property 16Mo3 (Typical Values) Yield Strength ≥ 220–275 MPa (depending on thickness) Tensile Strength 440–590 MPa Elongation ≥ 22% Max Service Temp Up to ~600°C Typical Applications: Boilers and superheaters in power plants Heat exchangers and pressure vessels High-temperature piping in chemical plants Refineries and process heaters handling hot gas and steam Summary: 16Mo3 offers a strong balance of thermal resistance, mechanical integrity, and fabrication flexibility, making it a reliable choice for medium-temperature pressure systems. It remains a widely used material for engineers designing equipment that operates continuously under heat and pressure in energy and process industries.
