Medical steel plate why so expensive

This is because the medical steel plate it is after the Xiaojun treatment, and the surface is also sprayed with a kind of paint, this kind of paint can play the role of sterilization, so the price will be so expensive. And medical steel plate is actually the use of titanium alloy, also known as medical titanium.

Medical titanium alloy used in the manufacture of implanted medical devices, prosthesis or artificial organs and auxiliary therapeutic equipment titanium alloy. There are mainly titanium 6 aluminum 4 vanadium, titanium 5 aluminum 2.5 tin and other alloys. They have a high specific strength, mechanical properties close to human bone, strength is far better than pure titanium, but also has fatigue resistance, corrosion resistance and excellent biocompatibility and other characteristics.

Production standards

Executive standards: GB/T 13810-2007, ASTM F67, ASTM F136

1. Ingots used for the production of processed materials should be used for vacuum self-consumption arc furnace melting or EB furnace melting plus vacuum self-consumption arc furnace melting, the number of times of melting shall not be less than two.

2. Self-consumption electrodes are prohibited to be welded by tungsten argon arc welding.

Chemical composition The chemical composition of the product shall comply with the provisions of GB/T3620.1 in the corresponding grades, pure titanium, TC4 and TC4ELI swollen hydrogen content should be no more than 0.010%. Demand-side re-inspection, the permissible deviation of chemical composition should be consistent with the provisions of GB/T3620.2.

Exterior dimensions and allowable deviations 1. medical titanium plate external dimensions and allowable deviations should be consistent with the provisions of GB/T 3621. 2. medical titanium rod external dimensions and allowable deviations should be consistent with the provisions of GB/T 2965. 3. medical titanium wire external dimensions and allowable deviations should be consistent with the provisions of GB/T 3623. 4. medical titanium wire external dimensions and allowable deviations should be consistent with the provisions of GB/T 3623.

Performance 1. The mechanical properties of the product should be tested on the heat-treated specimen blanks, specimens of the recommended heat treatment system: pure titanium 550 ℃ ~ 750 ℃, TC4, TC4ELI and TC20 alloy 700 ℃ ~ 850 ℃, insulation 0.5h ~ 3h, air cooling, coiled wire can also be used vacuum annealing. The supplier can make appropriate adjustments to the heat treatment system.
