astm b338 titanium coil processing method

The main finished products of titanium and titanium alloy include titanium tube, titanium plate, titanium wire, titanium coil and some titanium standard parts. The following titanium tube manufacturer introduces the processing method of titanium tube.

Titanium has excellent properties such as low density, high specific strength, corrosion resistance, small coefficient of linear expansion, and good biocompatibility. Titanium alloy tube as titanium equipment welding and titanium parts processing raw materials, generally used in two ways. One is to further process and manufacture standard parts, precision instrument structural parts, pendants, wire mesh, etc.. Titanium equipment, aviation spacecraft, military products, sporting goods welding; Third, precision instrument structural parts are directly used to control the fine wire of the equipment. These three uses of titanium and titanium alloy tube precision and surface quality have good requirements.

At present, the domestic and foreign production of titanium and titanium alloy wire is mainly used in stretching, grinding, annealing, acid and alkali washing, cut to length, straightening and other processes. In the whole production process, 20 stretching routes, 3 to 4 intermediate grinding, 10 intermediate annealing, 2 to 3 acid and alkali washing and straightening processes are required. Under the condition of high temperature heating, the diameter of the wire is controlled by the hole mold, the wire processing is difficult, the surface precision is poor, the absorption of hydrogen and oxygen is serious, the weight of the single disk is low, and it can't meet the requirements of high-precision titanium; the acid and alkali washing surface contamination is big, and it can only pickle the surface of titanium, and it can't produce bright titanium. Straightening process will make the titanium surface to form difficult to eliminate the straightening line, so that the titanium surface damage is more serious.

Titanium alloy tube using acid and alkali process, the use of straightening machine for titanium straightening, complex process, low production efficiency, low yield, resulting in a large amount of energy waste and environmental pollution.
