S355J2 steel plate is a low alloy high-strength structural steel, belongs to the European standard hot-rolled structural steel products, the same series of other materials such as S355JO, etc., equivalent to the national standard Q355D, is widely used in a variety of manufacturing areas, S355J2 steel plate not only has a high strength of the plasticity, but also has a good toughness to ensure that the use of a variety of loads and low-temperature conditions, and is not the effect of. Can well extend the life of the equipment, to protect the use of equipment and personal safety.
S355J2 steel plate implementation standards should be in line with the provisions of the European standard EN10025-2 (2004), J2 indicates -20 ℃ impact work of 27J.
S355J2 steel plate delivery is generally delivered in hot rolled condition, can also be normalized control rolled or normalized state delivery, if the demand side in accordance with the demand side to normalized delivery, the manufacturer will be named S355J2 + N, N on behalf of the normalized, or the demand side to increase the Z to the performance of the test, it will be based on the above increase in the Z to the grade; such as S355J2 + N-Z15, S355J2 + N- Z25, S355J2+N-Z35, thickness direction performance (Z-direction performance) shall comply with the provisions of EN10164:2004 for Z-direction grade.
S355J2 steel plate carbon content (melting analysis) is generally not greater than 0.20%, the sum of alloying element content is generally not greater than 2.5%, yield strength is not less than 295MPa, is a low alloy steel with good impact toughness and welding properties, has good mechanical properties, widely used in the construction of national economy bridges, steel structures, engineering machinery, offshore oil platforms, high-rise buildings and other fields, has a good reputation and put into use in large quantities.
