|
1. Tolerance is according to DIN Length: ﹢0~3 %, width: ﹢0~ 3%. |
|||||||
|
2. it is theoretical value for above spec, with the Length 1000mm, 500mm, 300mm. |
|||||||
|
3. Taking objective as standard, listed data are for reference only. |
|||||||
|
4. The products above have been strictly treated with tempering; the strain value has met the minimum. |
