Structural steel

The good welding properties and guaranteed strength of hot-rolled structural steel make it suitable for many applications. grades are also shown in these tables. When ordering qualities EN 10025 : 1993 suitable for cold forming, add the letter "C" to the end of the grade, e.g. S355J0C. Corus does not supply steel with increased copper content.

Typical applications

· transport · chassis parts · yellow goods · building and construction · tubes and pipes · sections and warehouse shelving · simple pressure vessels

Mechanical properties

The values shown for strength and elongation in tables 29-31 on pages 18 and 19 are for test pieces taken transverse to the rolling direction; those for the impact test are for test pieces taken in the rolling direction.

Chemical composition Standards

Hot-rolled structural steel complies with European standard EN 10025 : 1993 shown in table 26 below. Weldable fine-grained structural steels are also available as shown in European standards EN 10113-2 : 1993 and EN 10113-3 : 1993 in tables 27 and 28 on page 18. Former national standards and nearest related Structural steel meets the requirements of the cast analysis in the standards, as shown in tables 32-34 on pages 19 and 20.

Dimensions

The width and thickness limits are shown in tables 35 and 36 on pages 20 and 21.

Notes: 1. It is permissible to exceed the specified values provided that for each increase of 0.001% nitrogen the phosphorus maximum content will be reduced by 0.005%; the nitrogen content of the ladle analysis, however, shall not be more than 0.012%. 2. The maximum value for nitrogen does not apply if the chemical composition shows a minimum total aluminium content of 0.020% or if sufficient other nitrogen-binding elements are present. The nitrogen-binding elements shall be mentioned in the inspection document. 3. Values are in weight percentages.
