Steel sheet S 355NL DIN EN 10025-3
Steel sheet, grade S 355NL, is a hot rolled unalloyed fine-grained structural steel of high quality, normalized by rolling at temperature of 900 degrees. Fully meets the requirements of the EN 10025-3 standard.
It is recommended to buy such a sheet of metal for the manufacture of structural elements and parts operating in difficult conditions, under the influence of constant and significant mechanical and thermal deformation loads.
Special Properties
Sheet iron grade S 355NL is characterized by:
– high yield strength , at 355 megapixels, at ambient temperature;
– an excellent indicator of impact strength, at the level of 27 joules, at a temperature of -50 degrees;
– density 7.85 grams per cubic centimeter;
– good weldability. Welding work can be performed without preheating and subsequent heat treatment.
Fields of application
It is possible to buy a metal sheet, grade S 355NL, for the manufacture of elements structures of bridges, various supports, various hydraulic structures, parts of wagons, construction and logging machines, as well as attachments for them. composition S355NL (1.0546): EN 10025-3-2004
