S355J2 is one kind of non-alloy high-strength steel plates stipulated in standard of EN10025-2, 'S' means 'Structural Steel','355' means min yield strength of 355Mpa and 'J2' means -20℃'s impact test. With the referred chemical and mechanical properties, S355J2 Steel Plate has been widely used in the manufacture/ construction of engineering machines, ships(after approved by Society Classifications like ABS, DNV-GL, LR, BV, etc), Bridges, buildings, boilers and pressure vessels, electric power and kinds of vehicles. All the relevant applications are determined after evaluation of S355J2's performances of weldability, cutting, cold and hot working, heat treatment, malleability, uniform stability and large section hardenability, etc.

In S355J2, "S" stands for structural steel, "355" means that the yield strength is not less than 355MPa, and "J" means that its low-temperature impact work test temperature is -20 degrees Celsius (2 degrees Celsius, the temperature of the yield strength). 2" indicates that it is a low-alloy high-strength steel with higher strength and good low-temperature toughness compared to other similar steel grades.
S355J2 in the manufacturing process, due to its low carbon content, can be easily heat treated and welded while maintaining sufficient strength and toughness. These characteristics make S355J2 widely used in many engineering applications, such as Bridges, construction, pressure vessels, structural parts and other fields.
