16Mo3 Alloy Steel Tubes: Engineered for High-Temperature Performance

Our 16Mo3 tubes represent a class of low-alloy steels containing molybdenum and chromium, meticulously manufactured to deliver superior performance under sustained high temperatures and pressures. This alloy composition is the European standard (EN 10216-2) equivalent to ASTM A204 Grade A, making it a globally recognized material for critical pressure-bearing components.

Key Material Characteristics & Advantages:

• Excellent Creep Strength: 16Mo3 maintains its structural integrity and resists deformation over long periods under high stress and temperatures, which is crucial for components like superheaters.

• Good Oxidation Resistance: The alloy content provides a protective layer, reducing scaling and material loss in oxidizing atmospheres at elevated temperatures.

• Enhanced Weldability: 16Mo3 is known for its good weldability with standard procedures, allowing for easy fabrication and installation without significant risk of cracking.

• Resistance to Hydrogen Attack: The molybdenum content helps resist embrittlement and cracking caused by exposure to hydrogen at high temperatures, a common challenge in petrochemical processes.

Typical Chemical Composition (EN 10216-2):

• Carbon (C): ~0.12 - 0.20%

• Manganese (Mn): ~0.40 - 1.00%

• Silicon (Si): ~0.10 - 0.35%

• Phosphorus (P): max. 0.025%

• Sulfur (S): max. 0.020%

• Chromium (Cr): ~0.30 - 0.60%

• Molybdenum (Mo): ~0.25 - 0.35%

Mechanical Properties (Typical at Room Temperature):

• Yield Strength (Rp0.2): Min. 270 MPa

• Tensile Strength (Rm): 450 - 600 MPa

• Elongation (A): Min. 22%

Primary Applications:

16Mo3 tubes are indispensable in industries where equipment operates under extreme thermal stress.

• Power Generation: Boiler superheaters, reheaters, heat exchangers, and high-pressure steam pipelines.

• Boiler Manufacturing: For water tube and fire tube boilers in industrial settings.

• Petrochemical Industry: Components in refineries, including transfer lines and catalytic cracking units.

• Pressure Vessels: For containing gases or liquids at pressures significantly different from ambient pressure.

• Thermal Oil Systems: As pipelines in systems that use thermal oil for heat transfer.
