Reference Standards:

1. GB 228: Tensile test method for metals
2. GB/T 3620.1: Titanium and titanium alloy grades and chemical composition
3. GB/T 3620.2: Chemical composition and allowable deviation of titanium and titanium alloy products
4. GB 4698: Sponge titanium and titanium alloy chemical analysis method

Technical Requirements:

1. The chemical composition of titanium and titanium alloy bars must meet the rules in GB/T 3620.1. If retesting is needed, the allowable deviation must follow GB/T 3620.2.
2. The diameter or side length of hot-processed bars and their allowable deviations.
3. The diameter’s allowable deviation for cold-drawn rods after hot processing by turning (grinding) and cold rolling.
4. The roundness of the bar after hot processing should not exceed half of its dimensional tolerance.
5. The indefinite length of the processed bar is 300-6000 mm, while the indefinite length of the annealed bar is 300-2000 mm. Fixed or double lengths should be within these ranges, with an allowable deviation of +20 mm. The double length should also be included in the cutting quantity of the rod, with each opening quantity being 5 mm. Fixed or double lengths must be noted in the contract.
