Detailed Explanation of the Quality Inspection Process for Gr2 Titanium Plate

The production of Gr2 titanium plates (industrial pure titanium) in China adheres to a strict quality control system, with quality inspection procedures running through the entire process to ensure that the materials meet national standards (such as GB/T 3621) and international standards (such as ASTM B265).

The core processes of quality inspection are as follows:

Chemical composition analysis: Use spectrometers and other equipment to strictly test the content of impurity elements such as iron (Fe), oxygen (O), carbon (C), nitrogen (N), and hydrogen (H) to ensure that they meet the requirements of Gr2 grade.

Mechanical property testing: Samples are taken from each batch of plates, and tensile strength, specified non-proportional extension strength (Rp0.2), and elongation are measured on a universal testing machine to ensure that their strength and plasticity meet the standards.

Dimensional and shape inspection: Use a precision measuring tool, a laser rangefinder, to measure the thickness, width, length, and unevenness of the sheet metal and other dimensional tolerances to ensure compliance with the order requirements.

Surface quality inspection: The quality inspector visually inspects the surface of the board to ensure there are no harmful defects such as oxide scale, cracks, peeling, or inclusions. The surface after pickling should be silvery white and uniform.

Non-destructive testing: For plates with high standards, ultrasonic testing (UT) is used to detect hidden defects such as inclusions and pores inside the plates.

Through the strict quality control of multiple processes mentioned above, the final Gr2 titanium plates leaving the factory will be accompanied by detailed "Quality Certificates" to ensure their reliable performance, traceability, and meet the application requirements of high-end fields such as chemical engineering, Marine, and medical care.
