Titanium Fasteners
Titanium Grade 1, Grade 2 & Grade 5 Hex Bolts, Screws, Nuts & Washers Supplier
Extreme Strength-to-Weight Ratio, High Temperature Stability, and Superior Acid/Saltwater Corrosion Resistance
Product Overview
Kuldevi Forge & Fittings is a premier manufacturer and supplier of high-performance **Titanium Fasteners** in India. Our inventory includes **Titanium Grade 1**, **Grade 2** (commercially pure), and **Grade 5** (Ti-6Al-4V alpha-beta alloy) bolts, screws, nuts, and washers, manufactured to precise ASME B18.2.1 / DIN 933 tolerances for aerospace, defense, marine racing, chemical reactors, and oil drilling systems.
Commercially pure Titanium (Grades 1 & 2) offers outstanding resistance to oxidizing acids, organic compounds, and seawater pitting due to a natural, tenacious titanium oxide passivating film. **Titanium Grade 5** alloy is heat-treatable and provides an exceptional tensile strength of over 130 KSI (900 MPa) combined with low density (4.50 g/cm³), giving it a strength-to-weight ratio superior to structural steels and nickel alloys.
We specialize in custom machined Titanium fasteners, including aircraft-grade fasteners (DIN 84, DIN 912, DIN 965), thrust washers, socket head cap screws, and heavy hex nuts. Our products are rigorously tested to eliminate galvanic corrosion and hydrogen embrittlement in demanding engineering applications.
