HRC Medium Carbon Steel Sheets In Coil 1mm Thickness High Carbon Strength Hot Rolled Cold Rolled Carbon Steel Coil
Will cold rolled steel rust?
Because cold rolled steel sheet is prone to rusting, standard practice is to apply a rust-preventative oil at the exit end of the temper mill (the last processing step). Rust-preventative oils are different than forming lubricants in that they contain special corrosion-inhibiting additions.
