Heat Treatment

Titanium is a new type of metal. The performance of titanium is related to the content of impurities such as carbon, nitrogen, hydrogen, and oxygen. The purest titanium iodide has an impurity content of no more than 0.1%, but its strength is low and its plasticity is high. The properties of 99.5% industrial pure titanium are: density ρ=4.5g/cm3, melting point 1725℃, thermal conductivity λ=15.24W/(m.K), tensile strength σb=539MPa, elongation δ=25%, section Shrinkage rate ψ=25%, elastic modulus E=1.078×105MPa, hardness HB195.

Commonly used heat treatment methods are annealing, solution and aging treatment. Annealing is to eliminate internal stress, improve plasticity and organizational stability, and obtain better comprehensive properties. Usually, the annealing temperature of α alloy and (α+β) alloy is 120-200℃ below the (α+β)-→β phase transition point; solution and aging treatment is fast cooling from high temperature region to obtain martensite α′ phase and metastable β phase, and then heat preservation in the medium temperature zone to decompose these metastable phases to obtain finely dispersed second phase particles such as α phase or compounds, to achieve the purpose of strengthening the alloy. Usually, the quenching of (α+β) alloy is carried out at 40～100℃ below the (α+β)—→β phase transition point, and the quenching of metastable beta alloy is performed at 40～80℃ above the (α+β)—→β phase transition point. conduct. The aging treatment temperature is generally 450 to 550 °C. In addition, in order to meet the special requirements of the workpiece, the industry also adopts metal heat treatment processes such as double annealing, isothermal annealing, beta heat treatment, and deformation heat treatment.

Competitive Advantage:

A high-tech enterprise specializing in the production and processing of titanium materials. Since its establishment, the company has adopted the international advanced hydrogenation and dehydrogenation process, and firstly developed and perfected a set of modern production lines to produce domestic high-purity ultra-fine particle metal titanium powder. During this period, in 2001, we developed and produced a high-grade hypoxic sponge titanium powder, the ace product, which has been well received by customers at home and abroad. The company has more than 40 employees, including 8 technicians and technicians with high and intermediate professional titles. The company's hypoxic sponge titanium powder process has declared a national invention patent, and has established a quality, safety and environmental management system. Now the factory has passed the AS9100C:2009 International Aerospace and Defense Organization, ISO13458:2003 International Medical Device Management and Production System Certification and ISO9001:2008 quality management system certification

Application:

The titanium tube is light in weight, high in strength and superior in mechanical properties. It is widely used in heat exchange equipment, such as shell and tube heat exchangers, coil heat exchangers, serpentine heat exchangers, condensers, evaporators and conveying pipes, etc. Many nuclear power industries use titanium tubes as standard tubes for their units.
