Titanium Grade 2 Fasteners Manufacturer and Supplier in India

Q: Are Titanium Grade 2 fasteners magnetic?

No. Titanium Grade 2 is non-magnetic, which makes it suitable for applications such as MRI and electronics-adjacent hardware where magnetic materials may be unsuitable.

Q: Can Titanium Grade 2 bolts be used in seawater?

Yes. Titanium Grade 2 provides excellent resistance to seawater corrosion and is used for selected marine fastener applications where resistance to chloride environments is required.

Q: What is the difference between Titanium Grade 2 and Grade 5 fasteners?

Grade 2 is commercially pure titanium with moderate strength of approximately 50 ksi yield strength, while Grade 5 (Ti-6Al-4V) is a titanium alloy with roughly 2.5 times the yield strength and is used where higher clamp loads are required.

Titanium Grade 2 Fasteners are commercially pure grades of titanium used for high performance, lightweight, corrosion-resistant bolting in harsh industrial applications. They have a minimum tensile strength of 344 MPa and yield strength of 275 MPa and are manufactured to UNS R50400 and Werkstoff 3.7035. These fasteners have a density of about 4.51 g/cm³, which means that they have very high weight reduction. The naturally formed titanium oxide layer they have provides high chloride, marine and oxidizing resistance, and their ductility offers reliable installation and cold forming. Sachin Steel Centre is a reputed manufacturer and supplier of Titanium Grade 2 fasteners in India, providing Grade 2 fasteners in chemical processing, marine, desalination and other applications that are subject to corrosion.

Frequently Asked Questions

What are Titanium Grade 2 Fasteners?

Titanium Grade 2 Fasteners are commercially pure titanium bolts, nuts, screws, and other threaded components used where low weight and corrosion resistance are required.

What are the advantages of Titanium Grade 2 Fasteners?

They offer excellent corrosion resistance, low density of about 4.51 g/cm³, good ductility, and a minimum tensile strength of 344 MPa.

Are Titanium Grade 2 Fasteners corrosion resistant?

Yes. They provide excellent resistance to seawater, chlorides, oxidizing environments, and many corrosive chemicals due to their protective oxide film.

What is ASTM B348 for Titanium Grade 2 Fasteners?

ASTM B348 is a specification covering titanium and titanium alloy bars and billets, including Grade 2 material that can be used for manufacturing fasteners.

Are Titanium Grade 2 fasteners magnetic?

No, Titanium Grade 2 is non-magnetic, which is why it is specified for MRI and electronics-adjacent hardware.

Can Titanium Grade 2 bolts be used in seawater?

Yes ,Grade 2 is one of the most seawater-resistant fastener materials available and shows no pitting or crevice corrosion in long-term marine exposure.

What is the difference between Titanium Grade 2 and Grade 5 fasteners?

Grade 2 is commercially pure with moderate strength (~50 ksi yield); Grade 5 (Ti-6Al-4V) is an alloy with roughly 2.5x the yield strength, used where higher clamp load is required.
