Made of stainless steel and heat-resistant steelMixer truck racewayForgings, if they cannot be strengthened by heat treatment, need to be solid solution treated to improve the corrosion resistance and plasticity of the mixer truck raceway forgings and eliminate cold work hardening. Workpieces of complex shape and unsuitable for solution treatment may be subjected to stress relief annealing. In order to obtain stable corrosion resistance of the stainless steel containing titanium or niobium, stabilization annealing may be performed.

Mixer raceway forgings made of stainless steel and heat-resistant steel can be strengthened by heat treatment, and require improved strength, hardness and corrosion resistance. Low-temperature alloys should be used for quenching and tempering. Workpieces that require higher strength and elastic limit but do not require high corrosion resistance should be quenched and tempered using medium temperature alloys. Workpieces requiring good mechanical properties and certain corrosion resistance,Mixer truck racewayForgings shall be quenched and tempered with a warm alloy. Need to eliminate the processing stress, reduce the hardness and improve the plasticity of the workpiece, can be annealed. The workpiece that needs to improve the original structure can be subjected to the preliminary heat treatment of normalizing and tempering. Mixer truck raceway forgings Precipitation hardening stainless steel workpieces with good mechanical properties and corrosion resistance can be adjusted by solid solution plus aging, solid solution plus cold treatment or cold deformation plus aging.

The welded assembly is composed of stainless steel and heat-resistant steel, which can be strengthened by heat treatment, quenching, tempering or stress relief annealing according to the requirements of the forging drawing. When not strengthened by heat treatment.Mixer truck racewayWhen the forging assembly needs to improve the structure and corrosion resistance of the welding area and fully relieve the stress, it can be solved. For welded components of complex shape and unsuitable for solution treatment, stress relief annealing can be used. When corrosion resistance is the main requirement of welded components composed of stainless steel and heat-resistant steel, and theseMixer truck racewayWhen forgings can be strengthened or not by heat treatment, solid solution treatment and low temperature tempering should be carried out. When mechanical properties are required, low temperature quenching or temperature quenching should be carried out, Medium tempering. For welded components of complex shapes, stress relief annealing or high temperature tempering can be performed.
