16mo3 material properties

16Mo3 is a chrome-molybdenum (Cr-Mo) steel alloy commonly used in the production of pressure vessels and boilers. Here are some key material properties of 16Mo3:

Chemical Composition:

Carbon (C): 0.12-0.20%

Manganese (Mn): 0.40-0.90%

Silicon (Si): ≤0.35%

Phosphorus (P): ≤0.025%

Sulfur (S): ≤0.010%

Chromium (Cr): 0.30-0.60%

Molybdenum (Mo): 0.25-0.35%

Tensile Strength: The tensile strength of 16Mo3 typically ranges from 450 to 600 MPa (65,000 to 87,000 psi), depending on the thickness and heat treatment.

Yield Strength: The yield strength of 16Mo3 is approximately 280 MPa (40,500 psi), again depending on the thickness and heat treatment.

Elongation: The elongation of 16Mo3 is typically around 22% in a longitudinal direction.

Impact Strength: 16Mo3 exhibits good impact resistance at both room temperature and elevated temperatures.

Weldability: 16Mo3 has good weldability and can be welded using various processes such as arc welding, resistance welding, and gas tungsten arc welding.

Heat Resistance: 16Mo3 offers excellent heat resistance and can withstand high temperatures up to 600°C (1112°F). It retains its mechanical properties even at elevated temperatures.

Corrosion Resistance: 16Mo3 has moderate corrosion resistance. However, it is important to ensure appropriate protection measures or material selection when exposed to corrosive environments.

The combination of its high-temperature strength, good weldability, and mechanical properties makes 16Mo3 suitable for applications in the petrochemical, oil and gas, power generation, and process industries. It is commonly used in the fabrication of pressure vessels, boilers, heat exchangers, and piping systems that operate at elevated temperatures and pressures.
