Titan Metal Co., Ltd., Dongguan City, vacuum manufacturing services in China in various fields, the company is specialized in vacuum applications and equipment developed and manufactured and PVD coating processing of high-tech enterprises. Why do former piece titanium metal vacuum heat treatment, heat treatment of tool steel for? Annealing is a metal or alloy is heated to a suitable temperature, holding a certain time, and then slowly cooled with the furnace heat treatment process. Its essence is the steel after austenitizing be pearlite. Annealing function: ① reduce the hardness of titanium steel, improve the plasticity, in order to facilitate cutting and cold deformation; ② grain refinement, eliminating due to tissue caused by forging, welding defects such as IP vacuum titanium, homogeneous tissue components of steel, improve the performance of steel or heat treatment to prepare for the future; ③ eliminate the internal stress steel to prevent deformation or cracking. Annealing annealing method commonly used methods are fully annealed, the ball annealing, stress relieving, recrystallization annealing, diffusion annealing and isothermal annealing several. ① fully annealed also known recrystallization annealing, the iron-carbon alloy is fully austenitic, followed by slow cooling, get close to equilibrium state organizations annealing process. Suitable carbon content of 0.3% to 0.6% of the medium carbon steel and carbon steel. ② ball annealing the steel carbide spheroidization annealing process is carried out. There are commonly used ball annealing temperature ball annealing two ordinary ball annealing and the like, this process is mainly used eutectoid steel and over analysis of steel mold, measuring and cutting steel.

Why should vacuum die-casting industry products titanium? About a lot of product in the die casting industry titanium metal vacuum, according to Xiao Bian survey analysis, because in the early cycles of each die-casting metal titanium, the mold cavity is subjected to rapid thermal effect of the hot molten alloy, the working surface will produce compressive thermal stress; After the die-casting mold to spray lubricant, quenched, which is also on the surface tensile stress. In such alternating thermal stress, thermal fatigue will mold surface microcracks, with the increase in the number of cycles of the casting, rapid expansion of microcracks, and some extensions to the core section, turtle crack formation. If accompanied by a crack around the molten alloy to erosion and corrosion, mold surface will further damage the mold cavity, and eventually die early cracking or even scrapped. Die-casting process sticky, erosion, corrosion products caused by the high rejection rate, low productivity, and even cause damage to the mold and other issues has been troubled by various die-casting business major difficulty. _ _ Titanium IP vacuum titanium metal supplied by Titan Titan Metal Products Co., Ltd. of Dongguan City.
