SMA 50 CP steel Chemical composition and mechanical properties

SMA 50 CP steel is a type of weathering steel. For its chemical composition and general mechanical properties, please refer to the following information:

Chemical composition of SMA 50 CP steel (in mass fraction):
- Carbon (C): ≤ 0.18%
- Manganese (Mn): 0.60-1.30%
- Silicon (Si): 0.15-0.65%
- Phosphorus (P): ≤ 0.035%
- Sulfur (S): ≤ 0.035%
- Chromium (Cr): 0.30-1.25%
- Nickel (Ni): ≤ 0.65%
- Copper (Cu): 0.25-0.55%

Mechanical properties of SMA 50 CP steel (typical values, depending on specific production conditions):
- Yield strength: ≥ 345 MPa
- Tensile strength: ≥ 485 MPa
- Elongation: ≥ 20%
- Impact strength: ≥ 27 J at -20°C

It should be noted that these values may vary slightly depending on the specific production standard and batch of SMA 50 CP steel. When applying SMA 50 CP steel, always refer to the actual product specifications or technical documents to ensure accuracy and suitability.
