Specifications
Description
16Mo3 EN1092-1 Type 11 Weld Neck Flange
16Mo3 is a low-alloy steel grade primarily used for pressure vessels and boiler components operating at elevated temperatures. Defined in the EN 10028-2 standard, this material is commonly employed for tubes, pipes, and plates in power plants and industrial boilers.
Chemical Composition
Element Composition Range (wt%)
Carbon (C) 0.12 – 0.20%
Silicon (Si) ≤ 0.35%
Manganese (Mn) 0.40 – 0.90%
Phosphorus (P) ≤ 0.025%
Sulfur (S) ≤ 0.010%
Chromium (Cr) ≤ 0.30%
Molybdenum (Mo) 0.25 – 0.35%
Nickel (Ni) ≤ 0.30%
Copper (Cu) ≤ 0.30%
Nitrogen (N) ≤ 0.012%
Base Element Iron (Fe)
Element Significance
  • Molybdenum (Mo 0.25–0.35%) - The defining feature of 16Mo3 that improves high-temperature strength and creep resistance, while enhancing resistance to softening at elevated service temperatures.
  • Carbon and Manganese (C, Mn) - Carbon (0.12–0.20%) balances strength and weldability, while manganese (0.40–0.90%) increases strength and toughness and aids in deoxidation during steelmaking.
  • Low Phosphorus and Sulfur (P, S) - Kept at minimal levels to improve toughness and weldability while reducing the risk of hot cracking and brittleness.
  • Silicon, Chromium, Nickel, Copper (Si, Cr, Ni, Cu) - Present in controlled amounts to support strength, oxidation resistance, and structural stability without compromising weldability.
Applications
This chemical composition makes 16Mo3 an excellent choice for:
  • Boiler tubes and headers
  • Heat exchangers
  • Pressure vessels and piping in high-temperature service (typically up to approximately 500°C, depending on design codes)
Important Note: When working on design, fabrication, or material selection, always refer to the latest EN 10028-2 material standard and your project's specific material specification or mill test certificate (MTC). Exact limits and guaranteed values may vary slightly by product form and manufacturer.
