Pickled steel sheet

Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, rust or slag from ferrous metals. A strong acid solution is used to remove surface impurities. It is generally used to clean steels before carrying out other operations.

Hot rolled sheets of low carbon steel for its subsequent cold casting (UNE EN 10111: 2009), are supplied in the following formats:

Length (mm) Width (mm) Thickness (mm)
2000 1000 1,5 – 2 – 2,5 – 3 – 4 – 5 -6 – 8 – 10 – 12
2500 1250 1,5 – 2 – 3 – 4 – 5 -6
3000 1500 1,5 – 2 – 2,5 – 3 – 4 – 5 -6 – 8 – 10 – 12 – 15 – 20

Composition and mechanical characteristics of pickled steel sheet

Note: 1 MPa = 1 N/mm2

a.- The mechanical characteristics refer only to hot rolled products with or without hardening rolling, not stripped or pickled and oiled.

b.- Save where otherwise agreed in the request for quotations and the order, subject to the manufacturer’s criterion, nitrogen fixing elements such as titanium and boron may be added.

c.- Insofar as the width of the product permits, traction test specimens must be taken perpendicular to the rolling direction.

d.- If the product does not show any creep phenomenon, Rp0.2 must be used instead of ReL.

e.- It is recommended that DD11 type products be cast within 6 weeks of their availability date.
