Residual element content in steel: Cr≤0.08%, Ni≤0.10%, Cu≤0.15%. If the supplier can guarantee, no analysis is required. When the mass fraction of copper in the steel mass fraction cold rolled coil sc1 is greater than 0.15%, mass fraction cold rolled coil sc1 shall be dealt with through negotiation between the supplier and the buyer.
