10CrMo9-10 European Standard Container Steel

1.10CrMo9-10 steel plate implementation standard: EN10028-2
2.10CrMo9-10 steel plate delivery state:

The delivery state is normalized and tempered (N+T) or tempered (Q+T) can be selected according to the demand for different delivery states, 10CrMo9-10 steel plate is usually delivered in the normalized and tempered state with thickness below 60mm, greater than 60mm to 100mm in the normalized and tempered or tempered state, greater than 100mm to 250mm in the tempered state. According to the negotiation between the supply and demand sides, it can be delivered in untreated conditions.
