QStE340TM is a fine grain steel with excellent cold formability, which is especially suitable for automotive structural parts such as automobile girders and beams that require good cold formability and high or high strength requirements.
QStE340TM steel plate features:
High strength and hardness: QStE340TM steel has high strength and hardness, can withstand greater pressure and bending forces, and is not easy to deformation.
Good processing performance: the steel has excellent cutting and welding performance, easy to cut, bend, welding and other processing operations, thus simplifying the sheet metal manufacturing process and improving production efficiency.
Corrosion resistance: QStE340TM steel has been specially treated to have good corrosion resistance and can resist the attack of atmosphere, water and acid.
High wear resistance: Due to the advantages of hardness and strength, the steel can withstand frequent friction and wear.
Excellent fatigue resistance: QStE340TM steel is stable and resistant to fatigue breakage under cyclic loads.
Good low temperature performance: in low temperature environment, the steel can still maintain a high strength and hardness, not easy to occur cold brittleness.
