FAQ
Q: What is the meaning of S355 N?
A: S = This denotes that the material is a structural steel.
355 = An indication of the specified minimum yield strength as measured by a tensile test.
N = Is the final treatment condition of the material
Q: What is S355N EN 10025 3?
A: S355N steels are especially intended for use in heavily loaded parts of welded structures such as, bridges, flood gates, storages tanks, water supply tanks for service at ambient and low temperatures. EN 10025-3 is the Standard for hot rolled weldable fine grain structural steels in the normalized or normalized rolled.
Q: What is equivalent to S355N material?
A: S355J2+N steel plate is equivalent to S355N steel plate come from European steel specification EN 10025-2 hot rolled products of structural steels for non-alloy. S355N come from EN 10025-3 hot rolled products for normalized or normalized rolling steels.
Q: What is the difference between S355J2 N and S355JR?
A: S355JR steel has a minimum impact strength of 27 J under 20-degree temperature conditions while the second type of steel, S355J2+N has the same impact strength but with a temperature of -20 degrees.
