P355NL1 steel plate delivery status:

1. Normalizing is usually delivered. Normalizing rolling can be used instead of normalizing according to the negotiation between the supplier and the buyer. In this case, the sample should be simulated normalized according to the negotiated test frequency to verify that the performance meets the requirements.

2. Steel plates should be delivered by shearing or flame cutting
