Vad exakt är skillnaden mellan titanstål, rent titan och titanlegeringar förklaras kort idag .
The name titanium steel is not a standard academic name, but a commercial name. Because 316L stainless steel corrosion prevention, acid and alkali resistance is better than general stainless steel, the standard grade 022Cr17Ni12Mo2, mainly contains Cr, Ni, Mo, the number indicates the approximate percentage of content.
It can be seen that titanium steel is titanium-free, and its main component is still iron. This commercial name is used to differentiate it from other stainless steels when used as jewelry and to gain a higher value. It is also true that 316L stainless steel is in fact superior in cost and corrosion resistance to the usual common stainless steels.
Och vad som verkligen kan kallas titan är i allmänhet två huvudkategorier: rena titan- och titanlegeringar .
The highest titanium content is just made of titanium sponge, made of titanium tetrachloride by magnesium reduction, it is long like this: loose and porous, very low strength, can not be used directly as titanium, is used as the most upstream material of titanium, after melting, forging, rolling, processing into a variety of shapes of plates, wires, tubes and so on.
Titansinnehållet i titansvampen är nära 100% . Titanium är emellertid så aktivt att det reagerar lätt med syre, kväve och väte i luften när den kommer i kontakt med luften, så fullständig 100% renhet är nästan omöjlig .}
Generally speaking, titanium with a content higher than 95% becomes industrially pure titanium. Pure titanium is divided into TA1-TA4 according to its titanium content and impurity content, and we usually see TA1 and TA2. impurities are mainly oxygen, nitrogen, hydrogen, carbon, iron, etc. The higher the titanium content, Ju mer ren det är . desto högre titaninnehåll, desto mjukare är det, desto lägre styrkan pratar vi om, men desto bättre är det seghet .
Så när vi gör titanbältesspännen och titansmycken kommer vi att använda TA1 -material på den plats där kraften inte är särskilt stark, medan axeln, små skruvar som detta, kommer att använda TA2 -material .
När vi gör rena titankoppar kan vi inte använda TA2, ju högre renhet desto bättre, särskilt väteinnehållet måste vara lågt, annars är det att vara tillräckligt hög, det är lätt att spricka, eller se mer uppenbart, en linje med stretchlinjer eller pockmarks, skrot kommer att vara ganska hög .}
Then talk about titanium alloy, as the name suggests, is titanium and other metals, non-metals to form alloys. These metals and non-metals such as aluminum, molybdenum, vanadium, chromium, iron, zirconium, tin, oxygen, carbon and so on. Titanium alloys are subdivided into TA, TB and TC series according till deras metallografiska struktur .
Take the most commonly used TC4 titanium alloy as an example, its titanium content is 90%, aluminum 6%, vanadium 4%, so it is also called titanium 6 aluminum 4 vanadium.TC4 titanium alloy is the world's earliest developed and most widely used titanium alloy, and the earliest titanium alloy used for medical treatment, its production accounts for about half of the world's total production of all kinds of titanium alloy products, and in the aerospace industry is more than 80%. It has high corrosion resistance, higher strength than pure titanium, good toughness, processing and welding is relatively easy, so the overall performance is excellent, and also like pure titanium is not cause allergies.
Är rent titan eller titanlegering bättre?
This is not conclusive, different materials for different products, in general, excluding factors such as shape, titanium alloy material costs are higher than pure titanium. Of course, the titanium alloy here is to be a regular grade, is based on titanium to join other metals and non-metals, rather than adding a little titanium in other metals, containing a little bit of titanium to pretend to be titanium alloy of that snäll .
