Nearest Equivalent : JIS G3106 SM520B; BS4360 Gr50EE, S355K2G4

S355K2G3 High Tensile Steel Plates
S355 – a structural grade steel with a minimum yield strength of 355 N/mm² which widely used in engineering and
construction industries, S355 offers high yield and tensile strength and is supplied with a variety of treatments and
test options to ensure it is a highly usable steel in your various projects.

EN 10025 S355K2G3 HIGH TENSILE STRENGTH STRUCTURAL STEEL PLATES
S355K2+N and S355K2G3 are the same steel grades as both grades delivery condition are normalized.
G3 and N stand for normalized.  S355K2G3 steel plate Charpy V-Notch Impact Tested Longitudinl 40 Joules at -20 ˚C,
S355J2G3 steel plate Charpy V-Notch Impact Tested Longitudinl 27 Joules at -20 ˚C under 150mm thickness.
S355K2G3 steel plate is good in highly impact under low temperature condition projects.

S355K2G3 Characteristic
S355K2+N is a low carbon, high tensile strength structural steel which can be readily welded to other weldable steel.
With its low carbon equivalent, it possesses good cold-forming properties. The plate is produced by fully killed steel
process and supplied in n normalized or controlled rolling condition.

S355K2G3 Application
Structural application in freight cars, transmission towers, dump trucks, cranes, trailers, bull dozers, excavators,
forestry machines, railway wagons, dolphins, penstocks, pipes, highway bridges, building structures,
oil and gas platforms, offshore structures, shipbuilding, power plant, palm oil equipments and machineries, fans,
pumps, lifting equipments and port equipments.
