A36 Low-alloy structural steel plates for bridges construction steel plate

  A36 Low-alloy structural steel plates for bridges construction

  ASTM A36 Low-alloy structural steel plates (also known as popular low-alloy steel, HSLA) 1. Role Important for the production of bridges, ships, vehicles, steam boiler, high-pressure vessels, oil and gas pipelines, and large-scale steel layout. 2. Functional requirements (1) Strength and height: As usual, its yield strength is above 300MPa. (2) High toughness: The required increase rate is 15% to 20%, and the impact toughness at room temperature is greater than 600kJ / m to 800kJ / m. For large welded components, high intermediate fracture toughness is also required. (3) Excellent welding function and cold forming function. (4) Low cold hardening temperature. (5) Excellent corrosion resistance. 3. Identity (1) Low carbon: Because of the higher requirements for toughness, weldability and cold forming function, its carbon content does not exceed 0.20%. (2) Participate in alloy elements mainly composed of manganese. (3) Intervening with auxiliary elements such as niobium, titanium, or vanadium: A little niobium, titanium, or vanadium is forming fine carbides or carbonitrides in the steel, which is beneficial to the obtained ferrite grains and to improve the strength and toughness of the steel. In addition, intervening in copper (≤0.4%) and phosphorus (0.1%) can improve corrosion protection. Participation in rare earth elements can desulfurize and degas, purify steel, improve toughness and process functions. BBN Group has large stock of A36 Low-alloy structural steel plates in warehouse.
