The most common material used for the service in aerospace, marine, and chemical processing industries is commercially pure Titanium Grade 1 and also Titanium Grade 2 in Round Bars forms. Both of these commercially pure grades of titanium are biocompatible with excellent resistance to corrosion and strength-to-weight ratio, but each grade has different properties, which make it suitable for different applications.
This guide will cover the differences and applications of Titanium Grade 1 and Titanium Grade 2 Round Bars so that you may be able to choose the right material for your project.
Overview of Titanium Grade 1 Round Bar
Titanium Grade 1 is the softest and most ductile of the commercially pure titanium grades. The material is therefore primarily chosen for use in applications that have excellent corrosion resistance in a low-temperature environment with no stringent need for high mechanical strength.
Key Properties of Titanium Grade 1 Round Bar:
Corrosion Resistance: It has the highest resistance to corrosion amongst all commercially pure titanium grades, particularly in chloride-rich mediums like seawater.
Ductility: It is very much malleable, thus used in various applications, where formability and weldability are concerned.
Low Strength: As compared to all the other grades, it has the lowest mechanical strength, hence not quite favorable for more stressful applications.
Biocompatibility: Due to very high purity content, this is a great material in medical, especially dental, for implants and prosthetics.
Overview of Titanium Grade 2 Round Bar
The Titanium Grade 2 is slightly stronger than Grade 1 and most widely used commercially pure titanium grade. It is versatile in an industrial setting because of its formability, corrosion resistance, and strength balance.
Key Properties of Titanium Grade 2 Round Bar
Corrosion Resistance: Much like with Grade 1, the Titanium Grade 2 also generally offers excellent corrosion resistance capabilities, particularly with seawater and chemical environments.
Moderate Strength: This grade of strength is better than Grade 1, so it can be used in applications where better mechanical properties are required, yet it should not compromise on ductility.
Workability: This is relatively strong but still workable to great extent and can be welded as well as fabricated in many industries.
Biocompatibility: Biocompatibility of Titanium Grade 2 makes it popular in the medical industry due to its ability to have more strength as compared with Grade 1.
Main Differences Between Titanium Grade 1 Round Bars Vs. Titanium Grade 2 Round Bars
Mechanical Strength:
Titanium Grade 1 Round Bar: In this grade, the strength is lowest among the commercially pure titanium grades and, therefore, provides applications that require more crucial formability and corrosion resistance than necessary mechanical strength.
Titanium Grade 2 Round Bar: The grade attains higher tensile and yield strength as it can easily fulfil more demanding applications that allow moderate strength with excellent corrosion resistance.
Corrosion Resistance:
Titanium Grade 1 Round Bar: It is the most corrosion-resistant. A key benefit is in aggressive mediums like saltwater or chlorine-rich environments.
Titanium Grade 2 Round Bar: It is the same in corrosion resistance as Grade 1 but less effective in extremely corrosive medium.
Ductility and Formability:
Titanium Grade 1 Round Bar being more ductile, it can easily get shaped or formed to complex shapes and undergo cold-forming processes.
Titanium Grade 2 Round Bar: Less ductile than Grade 1, but can still be formed into excellent shapes and can be used in welding and fabricating to parts with increased strength.
Uses:
Titanium Grade 1 Round Bar: This is used since it offers good ductility combining with high corrosion resistance in industries like marine applications: heat exchangers and desalination, chemical processing, and in some medical devices where strength does not have to be that high but corrosion can become a big issue.
Titanium Grade 2 Round Bar This is the most widely used titanium grade, which is found in aerospace components, pressure vessels, marine equipment, and pipelines; titanium grade 2 has a good balance of strength, corrosion resistance, and formability.
Price:
Titanium Grade 1 Round Bar Cheaper because it has less strength, but applied typically for applications requiring low ductility.
Titanium Grade 2 Round Bar: More costly than Grade 1, the tensile strength of high and industrial usage is much wider.
How to Choose Appropriate Titanium Grade 1 vs Titanium Grade 2 Round Bars
Use a Titanium Grade 1 Round Bar when you need corrosion resistance and formability maximization, but you don’t necessitate strength. Applications involving marine exposure, chemical processing, and medical implants often require Grade 1.
Titanium Grade 2 Round Bar will be preferred if corrosion resistance balance with modest strength is desired. Aerospace, marine, and chemical industries are readily suitable for the application of components where more stress is to be managed and must not lose any corrosion resistance of Titanium Grade 2.
Conclusion
Though both titanium grades one and two will offer you high corrosion resistance as well as formability, they differ as one might have an advantage over the other in your application due to its mechanical properties. Titanium grade one is more in demand due to its superior corrosion resistance and better ductility, whereas titanium grade two is valued for strength and versatility. Working demands for your application will guide you in choosing the appropriate one for performance and longevity on the project.
