Supply dimensions, lead time and inspection are confirmed against the order and mill offer.

QStE340TM automotive steel is a low-carbon high-strength low-alloy steel, mainly composed of carbon, sulfur, phosphorus, nitrogen, manganese, chromium and other chemical elements. QStE340TM Steel under the SEW092 and Q-BQB 310-2009 standard, QStE340TM Steel uses high-sulfur and high-carbon components and is obtained by nitriding after rolling. The best performance, with excellent impact performance, can effectively reduce the weight of automobile structural parts and improve the structural strength of automobiles. QStE340TM low-alloy steel is mainly used in the production of automobile structural and non-automotive structural parts.

Legacy technical note · verification required

The performance of QStE340TM automotive low-carbon steel alloy is much higher than that of ordinary low carbon steel, the tensile strength can reach 1100MPa, and the elongation can reach 35%. QStE340TM automotive structural steel can be used in the production of automotive structures and non-automotive structures, such as automobile bodies and frames. Doors, fenders, wheels, axles, suspensions, etc., QStE340TM steel can also be used in the production of other industrial structural parts. QStE340TM high-strength steel has the advantages of light weight, durability, good rigidity, compact structure, easy processing, etc., and can meet the high performance requirements of automotive structural parts.

SEW092 QStE340TM automotive structural steel has excellent impact resistance, compression resistance, tensile performance, corrosion resistance, heat resistance and welding performance, and can be welded by fusion welding, MIG welding, TIG welding and other methods. In the manufacturing process of automotive structural parts, QStE340TM automotive steel needs to go through process steps such as cold rolling, heat treatment, and surface treatment. During the heat treatment process, it needs to go through multiple steps such as normalizing, tempering, quenching, and tempering to ensure Mechanical properties of steel.
