Steel sheet S 420NL DIN EN 10025-3
Steel sheet, grade S 420NL, is a hot-rolled normalized fine-grained structural steel of ordinary quality, produced in full compliance the requirements of EN 10025-3. At the same time, the price for a sheet of metal fully corresponds to its high performance characteristics.
more fine-grained and homogeneous structure, as well as improving mechanical properties, eliminating internal stresses and giving the metal special hardness.
Special properties
S 420NL – means to purchase rolled steel with:
– impressive impact strength, whose figure reaches 27 joules at a test temperature of -50 degrees, and 63 joules at a temperature of +20 degrees;
– high yield strength, 420 megapascals, at ambient temperature;
– density 7.85 grams per cubic centimeter;
– excellent weldability, not requiring special conditions.
Fields of application
For sheet iron, the price contributes to its widespread use in
