Titanium Grade 2 (UNS R50400)

Harder compared to titanium grade 1
Ductile by nature
Impact strength is high
Resistance Against corrosion
Weldability and formability are great

Description

Description

Grade 2 titanium is similar to grade 1 titanium with minor changes in its chemical composition.

But as a result of those small changes, it has the best strength to weight ratio among other pure metals. Due to its high strength and resistance to extremely high or remarkably low temperatures, it is widely used as an industrial metal.

This metal is the workhorse of the pure titanium group. When it comes to handling tough conditions and high corrosion, this alloy becomes the obvious pick. That is why you can find it in architecture, aerospace, automobile, marine, offshore drilling, sporting equipment, and much more.

Key features:

Industrial Application: CP2 Titanium is one of the most durable metals in its purest form, which is why it is preferred by various industries than its companions.
Heat Resistance: Titanium Gr2 normally has a higher heat resistance than other metals. So, the alloy can withstand a temperature but only up to 800°F without any problem.
Corrosion Resistance: Because of its chemical composition, it is highly resistant to corrosion. It can even be corrosion-free if used in seawater.
No Oxidization: As there is minimal corrosion taking place, it is free from oxidization under normal conditions.

Possible Alternative Grades:

Titanium alloy Grade 1: This is the softest of the bunch, but it has high ductility, formability, and weldability.
Titanium alloy Grade 3: You cannot find this in your conventional items list, as this alloy isn’t formable. Still, it holds great strength, making it is best suited for marine-based equipment.
Titanium alloy Grade 4: This grade of titanium lends its use for manufacturing the most of medical equipment. But it is not hard to find it in some other industry. It is the purest of the bunch and can withhold a lot of stress.

FAQ

How does Grade 2 Titanium get its formability feature?

Titanium Grade 2 comes with higher oxygen and iron levels as compared to other titanium grades. This combination brings in excellent formability & moderate strength along with superior resistance to corrosion.

How is titanium grade 2 different from titanium grade 5?

While CP Grade 2 Titanium comes with features such as light-weight & corrosion resistance, it has way lower alpha-beta strength. On the other hand, Grade 5 is an idiom for alpha-beta alloys, making it an excellent candidate for seamless formability.
