Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of LR EH36 hull construction steel circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and LR EH36 hull construction steel management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.
45Mn2 steel is added with manganese on the basis of No. 45 steel. After quenching and high temperature tempering, 45Mn2 steel can obtain high strength and good toughness, that is, it has good comprehensive mechanical properties, and is often used in manufacturing larger load shafts, connecting rods, fasteners, etc. The price of 45Mn2 steel is higher than that of No. 45 steel, LR EH36 hull construction steel. And the performance of 45Mn2 steel after heat treatment is better. 45Mn2 steel can be used as parts under higher stress and wear conditions, such as universal joint shaft, axle, connecting rod cover, friction plate, etc. The performance of 45Mn2 steel after heat treatment is better than No. 45 steel and worse than 40Cr steel.
LR EH36 hull construction steel, Q345 steel has good comprehensive mechanical properties. Q345 steel also has acceptable low temperature performance, good plasticity and weldability. Q345 steel can be used as structures, mechanical parts, building structures and general metal structures bearing dynamic loads such as medium and low pressure vessels, oil tanks, vehicles, cranes, mining machinery, power stations and bridges. Q345 steel can be used in hot rolling or normalizing state, and can be used in various structures in cold regions below - 40 ℃.
The blanking of the structural steel plate is first to find 90 degrees, and then use a tape measure and a powder line to draw the cutting range. According to the thickness of the carbon steel plate plus the cutting allowance, drilling is required. For the deep processing of LR EH36 hull construction steel structural steel sections or profiles: First use a square ruler or a curved ruler to find 90 degrees, and then use a square ruler or a ruler to cut the line and add the cutting margin to the hole.
The yield strength of LR EH36 hull construction steel, Q235 steel plate decreases with the increase of thickness. Q235 steel plate thickness≤16mm, yield strength is 235MPA; 16mm < Q235 steel plate thickness≤40mm, yield strength is 225MPA; 40mm < Q235 steel plate thickness≤60mm, yield strength is 215MPA; 60mm < Q235 steel plate thickness≤100mm, yield strength is 205MPA; 100mm < Q235 steel plate thickness≤150mm, yield strength is 195MPA; 150mm < Q235 steel plate thickness≤200mm, yield strength is 185MPA.
Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, LR EH36 hull construction steel sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding.
