Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.
45# steel is a common medium carbon quenched and tempered structural steel. The cold plasticity of 45# steel is general. Annealing and normalizing are slightly better than A514 grade E quenched and tempered steel quenching and tempering. 45# steel has higher strength and better machinability. After proper heat treatment, 45# steel can obtain certain toughness, plasticity and wear resistance. 45# steel is suitable for hydrogen welding and argon arc welding, not suitable for gas welding.
If a destructive accident occurs during the use of the boiler, it will cause serious losses. Therefore, other than some common strengths with A514 grade E quenched and tempered steel, the boiler steel plate must have good physical properties, mechanical properties and workability, and be strictly specified in the technical terms of the material standard to meet its safety in use. High temperature (above creep temperature) boiler steel plates are generally low-alloy heat-resistant steels, such as chromium molybdenum steel, chromium molybdenum vanadium steel, chromium molybdenum tungsten steel, etc.
In actual processing applications, the processing A514 grade E quenched and tempered steel thickness of flame cutting ranges from 6 to 200 mm, and the A514 grade E quenched and tempered steel cutting thickness can even reach 350 mm by replacing the air pipe and cutting torch nozzle. In order to better improve the cutting quality, the related process parameters will be slightly different when using flame cutting for materials of different thickness. The verticality of the cutting surface processed by the CNC flame cutting machine is generally high, and the slope can be controlled below 2-3°. The characteristic is that flame cutting performs better when cutting A514 grade E quenched and tempered steel with a certain thickness above 10mm.
BBN steel strictly control quality of our carbon steel plate, alloy steel plates and structural steel plates. For A514 grade E quenched and tempered steel ASTM A572 Grade 50 structural steel plate, Our Q/C Department will inspect dimension before shipment, making sure structural steel plate thickness tolerance and width, length tolerance are matchable to the A514 grade E quenched and tempered steel standard requirements. The company is a good ASTM A572 grade 50 structural steel plate supplier in the globle market and the head is located in China. Welcome to send us inquiry and questions about structural steel plate.
