Credit Bank Quality Case Analysis
Case analysis-mechanical properties
Credit bank members purchased stainless steel 316L/2B 0.38*1221*C rolls, and after slitting, the stamping process found that the defective rate was about 800kg. The on-site negotiation will compensate the customer’s loss with the price of the bad material at that time.
Analysis: There are many reasons for stamping cracking, involving the stamping process, die, and material properties. In these situations, normal handling requires on-site verification and on-site sampling to the steel plant for performance testing. If the steel mill confirms that it exceeds the normal first-level qualified product range, it will be dealt with. In the same special case, the cracking needs to be tempered to control, which requires special processing for customers who need to test performance when purchasing genuine goods to avoid large quantities of defects.
