Product Name: Titanium Pipe Standard: ASTM B338 Material: Gr1, Gr2 Unit Price: $25usd/kg-$40usd/kg Type: Welded/Seamless Shape: Round Outer Diameter: 9.52mm/12.7mm/15.9mm/19mm/21.7mm/25.4mm/32mm/33.4mm/38mm/45mm etc. Wall Thickness: 0.5-3.0mm Length: Max 12000mm Surface: Bright Features of Gr1 titanium pipe: 1. Gr1 titanium pipe has plasticity. The elongation rate of the high-purity titanium pipe can reach 50-60%, and the reduction of area can reach 70-80%. Although the strength of high-purity titanium pipe is low, the pure industrial titanium contains a small amount of impurities and the addition of alloying elements can significantly strengthen its mechanical properties, making its strength comparable to high strength. This means that as long as the industrial pure titanium pipe contains a small amount of interstitial impurities and other metal impurities, it can make it have both high strength and appropriate plasticity. 2. The specific strength (strength to weight ratio) of industrial pure titanium pipe is very high in metal structural materials. Its strength is equivalent to steel, but its weight is only 57% of steel. 3. Gr1 titanium pipe has strong heat resistance, and can still maintain good strength and stability in the atmosphere at 500°C. 4. Titanium pipe also has good low temperature resistance. Even at the ultra-low temperature of -250℃, it still has high impact strength and can withstand high pressure and vibration. 5. Strong corrosion resistance, this is because it has a particularly large affinity for oxygen, and can form a dense oxide film on its surface, which can protect titanium from corrosion by the medium. Therefore, titanium has good stability in acidic, alkaline, neutral salt solutions and oxidizing media, and has better corrosion resistance than existing stainless steel and other non-ferrous metals.
