Germany's IZFP has developed over 30 years of 3MA (micro magnetic, multi parameter, microstructure, stress analysis) non-destructive testing technology, which systematically integrates four micro magnetic testing methods

Introduction to the application industry of 3MA-PHS non-destructive measuring instrument for mechanical strength of automotive hot formed parts

The B-Pillars, Main Chassis Beams, and Tunnel reinforcements of the car body are all made of high-strength steel (AHSS), such as hardenable boron/steel alloys. This can minimize the weight of the vehicle to reduce fuel consumption, while ensuring maximum collision safety in the driver's cabin. In order to manufacture these components, consumers and suppliers in the automotive industry are increasingly relying on the so-called compression quenching hot forming process. Compared to traditional forming techniques, the production cost of compression quenching hot forming process is significantly reduced, and it saves fuel, which is beneficial for environmental maintenance.

The extensive use of hot formed stamping parts in automobiles and on-site non-destructive testing of mechanical strength of hot formed parts

In the hot forming process of compression quenching, the steel plate to be formed is heated to about 950 ℃, which is the austenitizing temperature, in a continuous furnace. Then, through a conveyor tool such as a robot, the hot sheet is placed into a pressure quenching machine equipped with a special water cooling system. As the quenching mold closes, the data undergoes deformation. Meanwhile, the cooling system instantly takes away the heat from the steel plate within a few seconds. Rapid cooling causes the steel plate to form a martensitic microstructure, ensuring that the material has both high strength and hardness.
