Annealing Tiny Stainless Steel Seamless Tube , Small Size Precision Steel Tube
Specifications:
Annealing is a kind of metal heat treatment process, which refers to the metal slow heating to a certain temperature, to maintain sufficient time, and then to cool down. The aim is to reduce the hardness, improve the cutting process, eliminate the residual stress, stable size, reduce the deformation and the crack tendency; refine the grain, adjust the structure, and eliminate the tissue defect. To be exact, annealing is a heat treatment process for materials, including metal materials and nonmetal materials. And the purpose of the new material is also different from the traditional metal annealing.

Description:
Purpose
(1) reduce the hardness and improve the cutting process.
(2) elimination of residual stresses, stable dimensions, reduced deformation and crack tendency;
(3) refine the grain, adjust the organization, and eliminate the organization defect.
(4) the organization and composition of the material, improving the material properties or preparing for the subsequent heat treatment.
In production, the application of annealing process is very extensive. According to the different purposes of the workpiece, the annealing process specifications have many kinds, such as complete annealing, ball annealing, and stress annealing.
