• The strength of ASTM A516 grade 70 is slightly higher than Q245R, Close to but a bit lower than Q345R. Most smelter in China, choose Q245R as the manufacturing material. Firstly, Q245R has less welding defects than Q345R, which is determined by its chemical composition. In addition, Q245R is better than Q345R in hydrogen corrosion resistance.


  • The working principle of the small mixer is: a mixing head with multiple interactive mixing blades, the mixing head can be directly placed on the ground for high-speed rotation, and the device can be controlled by hand to move at any angle and distance of 360 degrees, thus realizing Three-dimensional high-speed three-dimensional stirring.
