Product Details

Chemical composition: usually including carbon (C) ≤ 0.20%, silicon (Si) ≤ 0.55%, manganese (Mn) 1.00 - 1.70%, phosphorus (P) ≤ 0.025%, sulfur (S) ≤ 0.020%, niobium (Nb) 0.015 - 0.060%, vanadium (V) 0.02 - 0.20%, titanium (Ti) 0.02 - 0.20%, etc.
Mechanical properties: yield strength ≥ 460MPa, tensile strength 550 - 720MPa, elongation ≥ 17%. The low-temperature impact test temperature is -40℃, and the impact absorption energy is not less than 27J.
Delivery status: Common delivery status include hot rolling, controlled rolling, normalizing, normalizing rolling, etc.
Features: High strength: has excellent load-bearing capacity and can effectively reduce the weight of the structure.
Excellent low-temperature toughness: can still maintain good mechanical properties in extremely cold environments.
Application areas: Bridge construction in high-cold areas: ensuring the safety and stability of bridges under low temperature conditions.
Large-scale mechanical equipment: such as mining machinery and heavy cranes for polar operations.
Wind power generation: plays an important role in the manufacture of towers and key components of low-temperature wind farms.
