Other characteristics
Low temperature toughness:
SM490B steel plate has good low temperature toughness, suitable for use in low temperature environment.
Corrosion resistance:
The steel plate also has good corrosion resistance and is suitable for use in corrosive environments such as the ocean.


Pickling treatment:
In order to improve the surface quality and corrosion resistance of the steel, the SM490B steel plate may need to be pickling treatment during the production process.
