Titanium and titanium alloy plate
○1 Introduction
Titanium is a metallic element, gray, atomic number is 22, and relative
atomic mass is 47.87. Titanium can be combusted in nitrogen; its melting
point is high. Titanium and titanium alloy is a new type of structural
material, and it is mainly used in aerospace and marine industry. With
the nice performance of high strength, low density, anti-corrosion, good
mechanical properties, titanium and titanium alloy is widely used
chemicals, electronics, watches, glasses, sporting goods, machinery,
plating equipment, environment protection equipment etc. The most
widely used titanium plate is GR1 GR2 and titanium alloy plate GR5, GR7.

○5 Titanium plate production status
Hot working state(R)
Cold working state(Y)
Annealing state(M)
○6Production processing of titanium plate
Hot forging: It is kind of forging process above the crystallization
temperature of the metal
Hot rolling: rolling bellow the metal crystallization temperature
Cold rolling: the temperature of the metal is below its
recrystallization temperature
Annealing: it is a kind of metal treatment processing to heat the
metal to a certain temperature slowly, maintain a
sufficient time, and then cooling by a suitable speed.
Pickling: remove the oxide film on the metal surface
