ASTM B564 Titanium Alloy Gr.1/Gr.2/Gr.3 Flanges
What is Titanium Alloy Gr.1/Gr.2/Gr.3 Flanges
Titanium Alloy Gr.1, Gr.2, Gr.3 Flanges are commonly applicable in various types of flanges. These are commonly applicable where the resistance and strength is prioritized. This grade is commercially pure and enriched with excellent properties. These titanium alloy flanges are made using 99% of pure grade titanium. These flanges are more costly than most of the grades.
These titanium alloy Gr.1,Gr.2,Gr.3 flanges are commonly used for ending a connection. These flanges are so distinctive that they close the pipe but do not connect two lines. These flanges are available in two types: threaded and non-threaded. Threaded flanges usually have female threads which helps them to fit into the socket.
These flanges are highly durable and it has the ability to withstand all types of chemical and physical reactions. Titanium alloy Gr.1, Gr.2 and Gr.3 has excellent welding and pitting capacity. It also has high tensile and yield strength. The minimum tensile strength is 430Mpa whereas yield strength is 360 MPa.

Titanium Gr 2 Slip On Flanges, ANSI B16.5 Ti Alloy Gr 2 Orifice Flange, Titanium Gr 2 Nippo Flanges, Titanium UNS R50400 Pipe Flanges, Titanium Gr 2 Pipe Flanges.
Sumit Impex is the most trusted and prominent supplier, manufacturer and exporter of titanium alloy Gr.1, Gr.2 and Gr.3 flanges. We manufacture these flanges using high quality raw material. We also make sure that our every product is tested and certified
Grade Titanium alloy Gr.1, Gr.2 and Gr.3 is capable of bearing high heat, bad weather conditions and chloride involved in the environment. Titanium alloy Gr.1, Gr.2 and Gr.3 Flanges are highly used in industries like Aerospace, Petroleum refineries, Chemical Processing, Oil & Gas, Pharmaceutical, Thermal Processing, etc.
