SPECIALIZED TITANIUM FLANGES MANUFACTURER, ASTM B381 TITANIUM ALLOY FLANGES.

Kapoor Forge is leading Manufacturers, Suppliers, and Exporters of Titanium Flanges. It’s a essence with a low thickness, silverware color and high strength and infinitesimal number 22, Titanium is a type of chemical element which have symbol Ti. It’s thus important as an alloying agent with numerous essence including aluminium, molybdenum and iron. It has chemical compositions of 6 aluminum, 4 vanadium,0.25 iron,0.2 oxygen. Titanium Melting Point is 3034 °F (1668 °C). Titanium alloy Boiling Point is 5949 °F (3287 °C). Titanium is classified in varied grade including Grade 1, Grade 3, Grade 2, Grade 7, Grade 5, Grade 9, Grade 12, Grade 23.

We are ISO Certified Manufacturer and Stockist of ASME SB381 Titanium Alloy Flanges, Table D & Table E Titanium Blind Flange, Series A & B Titanium Slip On Flange, ASTM B381 Titanium CF Flange, Ti. Alloy Stub End Flange, PN10 PN16 Titanium Lap Joint Flange Pressure Rating, Titanium Weld Neck Flange at Reasonable Price.
