Welcome to BBN High Strength Steels Factory
The company was established in 2000, covering an area of more than 4,500 acres. It has fixed assets of 200 million yuan, and employs more than 1,200 people. It has now formed coking, sintering, white ash, pellets, ironmaking, S460QL steel equivalent steelmaking, steel rolling, oxygen production, gas and waste heat The complete circular economy industrial chain including power generation, comprehensive utilization of slag, soot and dust treatment, sewage treatment and recycling, etc. It mainly produces hot-rolled steel plates and S460QL steel equivalent carbon structural steels, high-quality carbon structural steels, low-alloy high-strength steels, medium and wide-band steels for cold-rolled stamping, and hot-rolled coils.
The strength indexes of S460QL steel equivalent pipeline steel mainly include tensile strength and yield strength. At the same time, the yield strength ratio (yield strength to tensile strength ratio) of pipeline steel is also required, which is generally in the range of 0.85-0.93. Pipeline steel shall have enough high impact toughness (crack initiation and crack arrest toughness). For the base metal, when the toughness of the S460QL steel equivalent material meets the requirements of crack arrest, its toughness generally can also meet the requirements of crack prevention.
S460QL 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.
As the thickness and hardness of S460QL steel equivalent increase, the tendency to crack at the cutting edge increases. In order to prevent the S460QL steel equivalent from cutting cracks, preheating should be carried out before S460QL steel equivalent cutting. Special attention should be paid to preheating to make the entire S460QL steel equivalent interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole S460QL steel equivalent cannot be preheated, the partial preheating method can be used instead.
