What material is the S355J2 steel plate

1. Introduction to S355J2 steel plate: S355J2 is a brand of European standard equivalent to the national standard Q355D. It is a low-alloy high-strength structural steel. Because of its good impact toughness and welding performance, this grade of steel plate is widely used in various industries.
2. The role of low-alloy high-strength structural steel: used in buildings, bridges, ships, vehicles, pressure vessels, and other structures. The carbon content (smelting analysis) is generally not greater than 0.20%, and the total alloying element content is generally not greater than 2.5%. Yield A low alloy steel with a strength of not less than 295MPa and good impact toughness and welding performance.
3. S355J2 steel plate implementation standard: EN10025-2
4. Delivery status of S355J2 steel plate: This grade is mostly delivered in a hot-rolled state.
PS: The specific delivery status should be stated in the contract.
5. Technical requirements of S355J2 steel plate: It can be used for Z-15, Z-259, Z-35, and Level I, Level II, and Level I flaw detection requirements.
6. Application scope of S355J2 steel plate:
S355J2 is European standard structural steel, mainly used in large machinery manufacturing, equipment bases, large welded steel structures, buildings, bridges, and other fields. With the continuous development of the economy and the demand for large-scale equipment, the demand for ultra-thick structural steel plates is gradually increasing, and the technology of steel plates is becoming more and more strict. At the same time, the added value of steel plates is relatively high, especially since the production of ultra-thick steel plates is difficult. relatively bigger. To achieve the production of ultra-thick steel plates, the steel ingots are used to produce uniform grain distribution during the rolling process, eliminating pores, shrinkage, and other defects inside the steel plates, meeting a good match of strength and impact toughness, and having better thickness-direction performance, making it suitable for mass production.
