Titanium rods

1 : GB 228 metal tensile test method 2: GB/T 3620.1 Titanium and titanium alloy grades and chemical composition 3: GB/T3620.2 Titanium and titanium alloy processed products chemical composition and composition allowable deviation 4: GB 4698 sponge titanium, titanium and titanium alloy chemical analysis methods

Titanium rod technical requirements

1: The chemical composition of titanium and titanium alloy bars should comply with GB/T 3620.1, the provisions of the need for repeated testing, the allowable deviation of the chemical composition should comply with the provisions of GB/T 3620.2.
2: The diameter or edge length of the hot-processed bar and its allowable deviation should be in line with the provisions of Table 1.
3: After hot processing by turning (grinding) polished bars and cold-rolled, cold-drawn bars should meet the allowable deviation of the diameter of the provisions of Table II.
4: After hot processing by turning (grinding) polished bars should not be more than half of its size tolerance.
5: Processing state of the bar's indefinite length of 300-6000mm, annealed state of the bar indefinite length of 300-2000mm, fixed length or times the length of the bar should be within the indefinite length. The allowable deviation of the fixed length is +20mm; the multi-length should also take into account the cut of the bar, each cut amount is 5mm.
