GB/T 3622-2023 in English

Interpretation of GB/T3622—2023 "Titanium and Titanium Alloy Strip and Foil" Standard

1. Background and Significance of Standard Revision

GB/T3622—2023 is the third revision of GB/T3622—2012. The main updates include:

• New chapters on terms and definitions
• Optimization of product classification and grade system
• Adjustment of specification ranges such as thickness and width
• Improvement of chemical composition analysis methods
• Strengthening room temperature tensile performance requirements

2. Comparative analysis of standard frameworks

3. Interpretation of the core content of the standard

3.1 Classification and labeling

The classification of strips and foils is mainly based on thickness, width and state. New grades include TA0, TA1G, TA2G, etc., which expand the application range of the materials.

3.2 Technical requirements

Chemical composition, external dimensions and allowable deviations, room temperature tensile properties, bending properties and appearance quality are the main technical indicators. In particular:

• Stricter tolerance range for chemical composition
• New high-precision dimensional requirements
• Refinement of tensile performance indicators for different grades

4. Implementation suggestions and precautions

When applying the new standard, companies should focus on:

• Update internal technical documents and testing procedures
• Strengthen employee training to ensure understanding of the new standard requirements
• Optimize raw material procurement and supplier management
• Establish a testing laboratory or cooperate with a third-party agency that meets the standards
