EN10025-3 standard S355NL round bar

S355NL round bar belongs to the European standard high-strength steel,which under EN10025-3 standard,full name is normalizing / normalizing rolling can be welded fine grain structure steel,high strength,especially in normalizing or normalizing plus tempering state has a higher comprehensive mechanical properties.S355NL round bar mainly used for large ships,bridges,power station equipment,medium and high pressure boilers,high pressure vessels,locomotives and rolling stock,lifting machinery,mining machinery and other large welded structural parts.

Normalized rolling,that is rolling within a certain temperature range,resulting in the state of the material equivalent to the state after the normalized rolling process,the mechanical properties of the value specified even after normalizing can be maintained.

As the product thickness and strength levels increase, cold cracks may occur. Cold cracks are caused by the following factors.

1, the diffusion of hydrogen in the welding metal; 2, the heat affected zone of the brittle organization; 3, welded joints tensile stress concentration
