Industrial pure titanium

- Jan 09, 2018 -

Industrial titanium is classified according to the content of impurity elements. It has excellent stamping process performance and weldability, is not sensitive to heat treatment and tissue type, and has a certain strength under satisfactory plastic conditions. Its strength depends on the gap element oxygen, nitrogen content. It has high corrosion resistance in seawater, but poor in inorganic acids. Generally used in the manufacture of -253 ~ 350 ℃ temperature work, with little force of a variety of sheet metal parts or forgings, rivets can also manufacture wire and pipe.

Containing a certain amount of oxygen, nitrogen, carbon, silicon, iron and other elements of the α-phase titanium. Titanium content of not less than 98%, containing a small amount of oxygen, nitrogen, hydrogen, carbon, silicon and iron and other impurities in the dense titanium metal. Oxygen, nitrogen, carbon, hydrogen and silicon are interstitial impurity elements and iron belongs to the alternative beta stable element. Oxygen, nitrogen and carbon can improve the room temperature tensile strength of titanium, but also reduce the plasticity of titanium. Therefore, the contents of oxygen, nitrogen and carbon in titanium all have strict limits, especially the oxygen content. The solubility of hydrogen in titanium is small and the reaction of hydrogen with titanium is reversible. The main effect of hydrogen on the performance of titanium is "hydrogen embrittlement", when the hydrogen content in titanium reaches a certain amount, it will greatly enhance the sensitivity of titanium to the gap, thus sharply reducing the impact toughness of the notched specimens and other properties. It is generally stipulated that the hydrogen content in titanium should not exceed 0.015%. Titanium is an indispensable material for cutting-edge science industries such as modern aeronautics, marine science and nuclear power generation. Titanium 48% lighter than the average metal, and toughness, acid and alkali resistance, corrosion resistance, high stability, high strength, good elasticity, etc., in line with the Department of Ergonomics, titanium non-toxic to humans, without any radiation.
