American standard: ASTM B348,ASTM F136, ASTM F67, AMS4928
A, reference standard Method 1:228 GB metal tensileexperiment
2: GB/T 3620.1 titanium andtitanium alloy grades and chemical composition
3: GB/T3620.2 titanium andtitanium alloy processing product chemical composition and allowable deviation
4: GB 4698 titanium sponge,titanium and titanium alloy chemical analysis method
Second, the technicalrequirements
1: the chemical composition oftitanium and titanium alloy bar should be consistent with GB/T 3620.1, theprovisions of the need to repeatedly test, chemical composition of thedeviation should be allowed to meet the provisions of GB/T 3620.2.
2: hot working bar diameter orlength and its deviation should be allowed to meet the provisions of the table1.
3: the car after hot working(grinding) light bar and cold rolled, cold drawn rod diameter deviation shouldbe allowed to meet the provisions of the table 2.
4: the car after hot working(grinding) out of roundness of light bar should not more than half of the sizetolerance.
5: processing state bar andfoot length of 300-6000 - mm, annealing state bar uncertain feet length is300-2000 - mm, length or times ruler length should be in the range of variablescale length. Specified length to allow deviation to + 20 mm;Times' amount of incisionlength should also be included in the bar, each all is 5 mm. The length ordouble foot length should be indicated in the contract.
