Choosing a Titanium Alloy: Is UNS R58640 Right for You?
When it comes to choosing a titanium alloy for your operations, there are a lot of factors to take into consideration. Do you need one with a low density? Does it need to be highly corrosion resistant? Should it be able to withstand high temperatures? You may find that UNS R58640 is the right titanium alloy for you, though there are a few things you should know about the alloy before jumping into a full scale production for your components.
The UNS R58640 titanium is commonly listed under the ASTM grade of titanium known as Beta-C or Grade 19. This is one of the stronger alloys and is used in the majority of high-strength applications. Additionally, it is the smallest group of alloys, falling into the beta alloy category and can be heat treated. It has a strong hardenability factor that needs to be considered as well.
You should take into consideration some of the various benefits that exist with UNS R58640. The titanium grade 19 alloy has a low density, a low thermal expansion, low wear resistance, and superior corrosion resistance. Just when you don't think it could get any better, you also have to look at the fact that it has non-magnetic permeability and high temperature mechanical properties.
Should you need titanium bars, tubes, or other machined components that are capable of yielding high strengths, the titanium beta-C grade is the one that you are likely going to use.
Regardless of whether you are shopping for finish components to use in the oilfield or in various other industries, you will want to consider the titanium alloy options that exist. For example, grade 5 is mixed with aluminum whereas grade 7 is on alloyed with palladium. Then you have titanium grade 2, which is pure titanium for commercial uses. The beta alloy that we are talking about with UNS R58640 is actually one of the stronger options available to you because of how it is graded and what it is mixed with.
Prior to forging, rolling, or even machining any various components, you will want to talk to engineers with a metallurgical background and discuss whether or not UNS R58640 is going to be right for your applications. You may be using it in the oil fields, the Marine markets, the military markets, or even for automotives. You will be able to enjoy increased life by using titanium and be able to reduce the overall weight.
It's important to consider such things as design and prototyping before sending your project into production. If you are not sure whether or not UNS R58640 is right for you, you may want to discuss the design with a team of engineers and possibly even have a few prototypes created - using a variety of different titanium alloy grades.
You may only have one opportunity to have something customized and so you will want to make sure that it is being customized to your needs. Out of all of the different grades of titanium, beta-C or grade 19 definitely has a lot of positive aspects because of its strength.
