Hot rolled steel sheet
EN 10028-2 Fields of use
Steels for manufacturing of boilers and pressure vessels
Typical applications
Boilers, pressure vessels, gas bottles, boilers and containers.
EN 10028-2 
Aspects
The surface of the strips must be clean and smooth, without any covers, cuttings, air holes, scratches, non-metallic and scale inclusions, lacks of material, superpositons and stratifications.
There are admitted the following defects of surface:- small local scratches and air holes, local exfoliations, inequalities resulted from rolling, in the limits of the deviations accepted in the case of the thickness
- a thin layer of oxides
- unevenness resulted from rolling or that remain after the falling of the scale, in the limits of the negative deviations to thickness
Delivery conditions
The sheet are delivered in rolled state or in normalized state obtained by the control of the temperature during and after rolling. The sheet with cut edge with the thickness to 40 mm are going to have their edges cut only by mechanical means, and those with the thickness over 40 mm are going to have their edges cut only by flame.
