Steel sheet S 355N DIN EN 10025-3
Buy sheet steel S 355N – means to purchase high quality unalloyed fine-grained structural steel, normalized by rolling at temperatures up to 900 degrees, followed by cooling under natural temperature conditions. This improves the mechanical properties of the metal. First of all, its hardness.
Special properties
Steel sheet price of which fully corresponds to its high performance properties, is characterized by:
– high yield strength, at 355 megapixels, at ambient temperature;
– impressive impact strength, at 40 joules, at -20 degrees ;
– with a density of 7.85 grams per cubic centimeter;
– good weldability. The use of arc welding requires full compliance with current regulations.
Fields of application
S 355N steel sheet is recommended for the manufacture of welded structures that will work in severe conditions of temperature and mechanical deformation effects. These can be components of bridges, various supports, railway cars, various mechanisms, and so on.
