Bangladesh is an important market to us. We cooperated with the National Railway, the National Tubes Limited (NTL) and so on state-owned enterprises. They have tenders regularly. And we would participate the tenders with our local agents. We have been the winner of NTL tenders for many times. API 5L grade B steel strips are their needed Q345NQR2 steel equivalent materials. They have special chemical composition, tolerance and so on requirements. We can fully meet their demands and guarantee timely delivery.
Q345NQR2 steel equivalent, Q345B low alloy plate performance: 1) High strength: Generally its yield strength is above 300MPa; 2) High toughness: The elongation is required to be 15% to 20%, and the room temperature impact toughness is greater than 600kJ/m to 800kJ/m. For large welded components, higher fracture toughness is also required; 3) Good welding performance and cold forming performance; 4) Low cold brittle transition temperature; 5) Good corrosion resistance.
