Solid Solution Technology - Hope Machinery

High efficiency in-line bright annealing technology

The solid solution process leads to a homogenization of the microstructure of the material, making the product more ductile and improving corrosion resistance. This treatment is necessary for complex further processing, for example in chemical plant construction or hydroforming.

HOPE adopts the most advanced in-line bright annealing annealing technology, which can improve the mechanical properties and tissue hardness of the material to a greater extent than ordinary annealing processes, improving the toughness and corrosion resistance of the pipe.
