The automobile structure normal strength hull structural steel GL-B steel coil is one of our featured products. The main standards for automobile structure steel coil are JIS G3113, EN 10149-2, Q-BQB 310-2009, SEW092, DIN 17102, etc. The automobile structure steel coil is always pickled. For the steel coil, our processing center provide slitting, cutting etc. services. Our main automobile structure steel grades are SAPH440, S355MC, S500MC, S700MC, QStE380TM, QStE500TM, normal strength hull structural steel GL-B etc.
20# steel is carbon steel with carbon content of about 0.20%. It belongs to low carbon steel with high quality. The equivalent material of 20# steel is S20C. 20# steel has low strength and hardness, good plasticity and toughness, good carburizing effect and good weldability. 20# steel is often used to make pressure parts (such as gasket, chain piece), carburizing parts (gear, CAM), welding parts, plastic mold, etc.
Blast furnace ironmaking is a traditional ironmaking method based on coke energy. It cooperates with converter steelmaking and is the main method of producing normal strength hull structural steel GL-B steel at present. This dominance of blast furnace ironmaking is not expected to change for quite a long time. The essence of blast furnace ironmaking is the reduction of iron. Besides, coke is used as fuel and reducing agent. At high temperatures, iron ore or iron-containing raw materials are reduced from an oxide or mineral state to liquid pig iron.
EN10025-6 S960QL structural steel plates are quenched and tempered high strength steel with yield strength of 590Mpa ~ 960MPa. normal strength hull structural steel GL-B, S960QL steel plates have technical requirement of flaw detection, Z15 Z35 thickness direction performance requirements, high strength and high toughness requirements and so on.
