What is the difference between bp440 steel with high quality and steel grade A36

We have a very BP440 steel with high quality extensive commodity information network, with partners all over the world, and have become the full authority of many European and American traders in China. Under the guidance of the business philosophy of "creating the best service" and through the unremitting efforts of all employees, we have achieved remarkable results.

SM490B steel, BP440 steel with high quality is a kind of low carbon welded structural steel. With this low carbon equivalent, it can produce good cold forming properties. SM490B steel plate is usually supplied in hot rolling or controlled rolling delivery conditions. The SM490B is commonly used in the engineering and construction industries. It has high yield and tensile strength, and provides a variety of processing and testing options to make it highly available in your construction projects.

BP440 steel with high quality, Chinese grade 45 steel belongs to high quality carbon structural steel. The application of BP440 steel with high quality, Chinese grade 45 steel depends on its various properties. BP440 steel with high quality, Chinese grade 45 steel has certain toughness and plasticity, high strength and good machinability. Good comprehensive mechanical properties of Chinese grade 45 steel can be obtained by quenching and tempering treatment. Chinese grade 45 steel is suitable for manufacturing high strength moving parts, such as air compressor, piston of pump, impeller of steam turbine, rolling shaft, connecting rod, worm, rack, gear and pin in heavy and general machinery.

With the increase of temperature, the yield limit of BP440 steel with high quality will decrease monotonically, but the tensile strength of BP440 steel with high quality will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of BP440 steel with high quality. Near the blue brittleness temperature, the BP440 steel with high quality strength increases and the plasticity decreases. The elongation and section shrinkage of BP440 steel with high quality increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.

EN10113 S275M is a technical delivery conditions for thermomechanical rolled weldable fine grain structural steels.S means the structural steel, M means the delivery condition.The EN10113 S275M steel is equivalent to DIN StE285TM,UNI FeE275KGTM. EN10113 S275M steel plate/sheet,EN10113 S275M steel plate/sheet, under EN standard, we can regard BP440 steel with high quality, S275M steel plate/sheet for Fine-grain structural steels, thermomechanically rolled steel.

We have replenish steel materials stocks, now there are huge stocks of S355JR, A36, BP440 steel with high quality A572 Gr 50, 16Mo3, A516 Gr 70, ABS grade A, AH32, AH36, EH36, SPA-H, SG295,SM700C etc steel materials. We can arrange delivery for those stock steel products within short time. Meanwhile, we also provide further processing for the BP440 steel with high quality steel materials, such as cutting, drilling, bending, welding, etc. Please do not hesitate to contact us if you have any steel demands.

The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.
