What is the delivery status of SM490B steel plate?

The thickness 80mm steel plate, the delivery state is hot rolled; Steel plate thickness ≥80mm.
Delivery status: normalizing, tempering, annealing and quenching (Cham fire)
Normalizing: The steel plate is heated to a suitable temperature for cooling in the air.
Tempering: the steel plate is kept at an appropriate temperature for a long time before cooling.
Annealing: the steel plate is heated to a certain temperature and cooled slowly according to the heating time of different materials and specifications.
Quenching: the steel plate is heated and kept warm in water, oil or other inorganic salts and other media for rapid cooling.

The strength of SM490B steel plate is 490MPa. It is mainly used in buildings, Bridges, ships, rail vehicles, oil tanks, containers and other buildings requiring advanced solderability.
Note: trace alloying elements can be added if necessary.
