S355J2+N is a steel grade that is both good weldable and machinable. The material is used extensively in machinebuiliding, shipbuilding and offshore industry.
S stands for Structural, 355 is the yield strength in N/mm² (MPa) for th smallest thickness range.
J2 relates to the Charpy impact test value: 27 Joules at -20°C . + N indicates that the material is normalized.
S355J2+N is kept in stock in thicknesses of 4 to 600 mm and can be delivered with 3.1 and 3.2 certificate.
