EN10113 S275N steel

S275N steel is carbon and low alloy steel under the standard EN10113. EN10113 S275N means when the temperature is not less than -20℃, the minimum impact values is required. The delivery condition for S275N steel is normalizing rolling.

S275N steel processing properties: Cold cracks may occur as the thickness and strength level higher. Cold crack is integrated by the following factors: 1, The amount of diffusion hydrogen in the welding metal. 2, The brittleness of heat affected zone 3, The tensile stress concentration at welding joint.
