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.
About 2ton for each bundle
5 - 5.8m, 6m,double random length
(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
(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.
Tube Dimension and tolerance
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..
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.
Our factory is near to raw material market and high-speed way, the
producing cost is low.
Our factory have long history for producing stainless steel
seamless tube,both producing and testing
machine is advanced and perfect.
Our factory was certificated by BV/ISO/LR/RINA/CCS/GL/ABS/DNV,
which can improve the quality.
We participated in many famous projects with our tubes.
