|
Hot-rolled structural steel is suitable for general use because of its guaranteed strength and good weldability. |
|
|
Applications |
|
|
Hot-rolled structural steel can be used for welded and bolted constructions.
- automotive
wheel rims
chassis parts
- building and construction
- tubes and pipes
- sections and warehouse shelving
- simple pressure vessels

If grades are ordered, suitable for cold forming, this should be indicated by adding the letter C to the grade at the time of ordering, for instance: S355J0C. The steel grades supplied by Tata Steel Strip Products IJmuiden are always fully killed. Steel grades with an increased copper content are not available. |
|
|
Mechanical Properties |
|
|
Structural steel has the following mechanical properties, measured transverse to the rolling direction. The impact test however, is measured parallel to the rolling direction. |
