ASTM B265 is a standard specification for titanium and titanium alloy sheet materials, which includes information regarding dimensional tolerances and inspection methods for titanium sheets. For GR2 titanium sheets, here are the typical standard tolerance dimensions and precautions during inspection:

Standard Tolerance Dimensions:

1. Dimensional Tolerance: Generally controlled by the manufacturer during production and can be found in ASTM B265. For GR2 titanium sheets, typical tolerance values for thickness, length, and width should adhere to the standards specified.

2. Surface Quality: The surface of GR2 titanium sheets should be smooth, free from visible defects such as dents, cracks, or scratches.

Precautions during Inspection:

1. Certification Verification: Ensure compliance with ASTM B265 specifications and verify the accompanying certification documents.

2. Visual Inspection: Examine the surface of GR2 titanium sheets for any visible irregularities or defects.

3. Dimensional Measurement: Utilize appropriate measuring instruments to verify thickness, length, and width dimensions against standard tolerances.

4. Chemical Composition Analysis: Perform analysis to confirm that the chemical composition of GR2 titanium sheets falls within the specified range.

5. Mechanical Property Testing: Conduct tests to assess mechanical properties such as tensile strength, hardness, etc., to ensure they meet required standards.

6. Surface Treatment Examination: If subjected to surface treatments, assess the quality and uniformity of the treatment applied.

7. Packaging Inspection: Ensure the packaging of GR2 titanium sheets is intact and adequate to prevent damage during transportation.

During inspection, adhere to the guidelines outlined in ASTM B265 and employ suitable equipment and methodologies. If unsure about inspection procedures, seek assistance from qualified professionals or testing organizations.
