EN Standard Logo

High Strength Low Alloy Structural Steel to EN 10025:2004 S355 Standard

Use:

The S355 steel specification covers several grades of carbon steel plates of structural quality for general application, such as coldforming, i.e. bending, folding, bordering and flanging.

The steel grades of the JR, JO, J2 and K2 categories are in general suitable for all welding techniques.
