The main difference between Gr1 and Gr2 lies in the content of iron, oxygen and nitrogen. Due to the different contents of the above elements, the strength is also quite different, especially the oxygen content. A difference of 0.01% in oxygen content will bring a strength difference of tens of MPa. Therefore, there are some differences in subsequent processing performance. However, for the corrosion resistance of the material, the two are almost equivalent. Generally speaking, pure titanium GR.1 and GR.2 are basically used to manufacture various working conditions with a temperature of -253 to 250°C and low stress.

National standards:

National standard: GB/T 3622
American standard: ASTM B265

Dimensions:

Thickness: ≤0.1mm
Width: ≤600mm
Length: customizable
Weight per roll: 0~100kg

Main ingredients:

Mechanical properties:

Tensile strength: 270Mpa ≤ ob ≤ 410Mpa, yield strength ob≥ 165Mpa: elongation: δ≥27%.

Supporting welding materials:ERTi-1.

Corrosion resistance:

Titanium has excellent corrosion resistance in alkaline solutions such as sulfuric acid, hydrochloric acid, nitric acid and sodium hydroxide, as well as in moisture and seawater. However, titanium cannot resist the corrosion of hydrofluoric acid.

Titanium is very stable in the atmosphere, and a dense oxide film is formed on the surface, which can maintain the metallic luster; but when heated to above 600℃, the oxide film loses its protective effect.

Application areas:Aerospace, plate heat exchangers, bellows compensators, expansion joints, seawater desalination, desulfurization and denitrification, chemical equipment and civilian tableware industries, etc.
