Description:
ASTM TP321 Stainless Steel Pipe
Purpose
(1) reduce the hardness and improve the cutting process.
(2) elimination of residual stresses, stable dimensions, reduced deformation ;
(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.

The mechanical properties of steel is an important index to ensure the final use of steel (mechanical properties), it depends on the chemical composition and heat treatment system. In the steel pipe standard, according to the different requirements, the tensile properties (tensile strength, yield strength, yield strength, elongation) and hardness, toughness index, as well as high and low temperature performance, etc..
ASTM TP321 Stainless Steel Pipe Applications:
Used in industries as chemical engineering, petroleum, medicine, food, energy, nuclear power, aerospace,
environmental protection, boiler, gas, war industry, machinery, ship building and so on.
