S460N Steel Plates for Heavy Engineering & Construction

EN S420N High Strength Steel for Structure is a high-strength, fine-grained, normalized structural steel manufactured according to European standard EN 10025-3. It is designed for welded structural components requiring high strength, good toughness, and excellent weldability, especially in moderately low temperature environments (minimum -20°C).

Description

Technical Parameters

EN 10025-3 S420N,S420N STEEL,S420N STEEL PLATE shall be done heat treatment under Normalized.Normalized rolling process in which the final deformation is carried out in a certain temperature range leading to a material condition equivalent to that obtained after normalizing so that the specified values of the mechanical properties are retained even after normalizing. In international publications for both the normalizing rolling for steel plate s420n, as well as the thermomechanical rolling, the expression "controlled rolling" may be found. However in view of the different applicability of the products a distinction of the terms is necessary.
