The reasons for the burst of 304 seamless steel tube are as follows:




1. 304 seamless polishing flatness is insufficient to produce deflection.
2. Peeling ring has no demagnetization process and no material return before production; production has broken needle spring card inventory.
3. 304 seamless defective materials are easy to break in subsequent processing.
4. WEDM error handling cable WEDM, the gap is not right, did not make a clear angle.
5. Incorrect deformation during heat treatment and quenching and tempering.
6. The design process 304 seamless strength is not enough, the blade spacing is too close to 304 seamless structure is unreasonable, and the number of non-template pads is insufficient.
7. Layer stamping production awareness, position is not in place, do not use air gun, still continue to produce cracked templates.
8. Selection of tonnage punch equipment, stamping force is not enough, the next transmission mode is too deep.
