S355-K2

S355K2+N Steel Plate EN 10025 – 2 : 2004   1.0596

S355 – offers high yield and tensile strength with a minimum yield strength of 355 N/mm² , a structural grade steel which is widely used in engineering and construction industries, can be supplied with a variety of treatments and test options to ensure that it is a highly usable steel in your various projects.

S355K2+N is welder-friendly, low carbon, high tensile strength structural steel, can be readily welded to other weldable steel. For its low carbon equivalent, it possesses good cold-forming properties. The plate is produced by fully killed steel process and supplied in a normalized or controlled rolling condition

S355K2+N and S355K2G3 are the same steel grades as both grades delivery condition are normalized. G3 and N stand for normalized. S355K2+N steel plate Charpy V-Notch Impact Tested Longitudinal 40 Joules at -20 ˚C, S355J2+N steel plate Charpy V-Notch Impact Tested Longitudinal 27 Joules at -20 ˚C under 150mm thickness. S355K2+N steel plate is good in highly impact under low temperature condition projects.
