Writer:DJ-samSource:CSM Date:2014-03-28 10:22

Titanium bar manufactures are mainly use two production standard, one is Chinese Standard: GB/T13810,GB/2965-2007,Q/BS5331-91; Another is American Standard: ASTMB 348,TSTMF67,AMS4928 ,ASTMF 136.

Besides, the referenced standards are mainly:

1: GB228 Metal tensile test.

2: GB/T3620.1 Titanium and titanium alloy’s chemical components and grades.

3: GB/T3620.2 Titanium and titanium alloy processed product’s chemical component and the component’s allowable deviation.

4: GB4698 Titanium sponge, titanium and titanium alloy’s chemical component’s analysis method.

The above are all about the titanium production’s standard.

As for the technical requirements, here we will also give a brief introduction:

1.Titanium and titanium alloy bars composite chemical component should satisfy the GB/T3620.1 requirements. When it needs the repeated examination, its chemical component should also comply to the allowable tolerance range.

2.Hot worked bar’s diameter and allowable tolerance should comply to the sheet 1 requirement.

3.The hot worked bar’s diameter tolerance which has finished the grinding should also comply to the sheet 2 requirement.

4.The hot worked bar’s ovality can’t exceed half of its size tolerance.

5.The random length for machining bar is 300~6000mm, but the annealed bar’s random length is 300~2000mm, so the fixed length or multiple length should be within the random length range. Meanwhile, the fixed length requested allowable deviation is +20mm, but if it’s the multiple length, then you should include the bar’s cutting quantity, and each cutting is 5mm. So the fixed length or multiple length should be identified in the contract.
