S355J0W and S355J2W are both weathering structural steels that conform to the European standard EN 10025-5:2019. They have the same strength, weather resistance and weldability. The core difference is in the low temperature impact toughness level (J0 is 0℃, J2 is -20℃).
We compared and analyzed S355J0W with other similar materials in terms of chemical composition, mechanical properties, weather resistance, impact toughness, and weldability.
With its high strength, excellent weather resistance, good low-temperature toughness and weldability, S355J0W weathering steel has become a core material for modern bridge engineering, perfectly meeting the design requirements of bridges that require no painting, long service life and low maintenance.
ASME SA516 Grade 70 is a material standard belonging to Section II, Part A of the ASME (American Society of Mechanical Engineers) specification. It is a carbon steel plate material widely used in the pressure vessel and boiler industries.
