Product Name:High Quality ASTM B861 Grade 9 Seamless Titanium Pipes Demension:OD1.5mm-500mm                         W.T: 0.15mm-20mm                         Length:Less than 15m Material:Gr1,Gr2,Gr3,Gr5,Gr7,Gr9,Gr12                  3.7025,3.7035,3.7235,3.7195,3.7105                  Item1,item2,item3 Material Grade Introductions Gr1 Grade 1 titanium is the first of four commercially pure titanium grades. It is the softest and most ductile of these grades. It possesses the greatest formability, excellent corrosion resistance and high impact toughness.Because of all these qualities, Grade 1 is the material of choice for any application where ease of formability is required and is commonly available as titanium plate and tubing. Gr2 Grade 2 titanium is called the "workhorse" of the commercially pure titanium industry, thanks to its varied usability and wide availability. It shares many of the same qualities as Grade 1 titanium, but it is slightly stronger. Both are equally corrosion resistant. This grade possesses good weld ability, strength, ductility and formability. This makes Grade 2 titanium bar and sheet are the prime choice for many fields of applications. Gr3 This grade is least used of the commercially pure titanium grades, but that does not make it any less valuable. Grade 3 is stronger than Grades 1 and 2, similar in ductility and only slightly less formable-but it possesses higher mechanicals than its predecessors. Grade 3 is used in applications requiring moderate strength and major corrosion resistance. Gr5 Known as the "workhorse" of the titanium alloys, TI 6Al-4V , or Grade 5 titanium, is the most commonly used of all titanium alloys. It accounts for 50 percent of total titanium usage the world over. Its usability lies in its many benefits. Ti 6Al4V may be heat treated to increase its strength. It can be used in welded construction at service temperatures of up to 600° F. This alloy offers its high strength at a light weight, useful formability and high corrosion resistance. Ti 6AI-4V's usability makes it the best alloy for use in several industries, like the aerospace, medical, marine and chemical processing industries. Gr7 Grade 7 is mechanically and physically equivalent to Grade 2, except with the addition of the interstitial element palladium, making it an alloy. Grade 7 possesses excellent weldability and fabricability, and is the most corrosion resistance of all titanium alloys. In fact, it is most resistant to corrosion in reducing acids.Grade 7 is used in chemical processes and production equipment components. Gr9 Grade 9 titanium is also know as Ti-3AL-2.4V or simply Ti-3-2.5. Grade 9 is grouped in with the commercially pure grades because it is cold rollable. Grade 9 strengths fall between Grade 4 and Grade 5. It has excellent corrosion resistance and is used in aerospace and industrial applications.Grade 9 can be used at higher temperatures than Grades 1 through 4. Grade 9 is used in Aerospace, Chemical processing, Medical, Marine, Automotive, Consumer applications and Transporation. Gr12 Grade 12 titanium holds an "excellent" rating for its high quality weldability. It is a highly durable alloy that provides a lot of strength at high temperatures. Grade 12 titanium possesses characteristics similar to 300 series stainless steels. This alloy can be hot or cold formed using press brake forming, hydropress forming, stretch forming or drop hammer method. Its ability to be formed in a variety of ways makes it useful in many applications. This alloy's high corrosion resistance also makes it invaluable to those manufacturing equipment where crevice corrosion is a concern.
