S355J0 carbon steel material Material Specification

S355J0 carbon steel material,EN10028-2 P235GH steel plate is a non-alloy quality steel with high temperature performance, executive standard: EN10028-2. Steel number: 1.0345. , P235GH pressure vessel steel has good plasticity, toughness, cold bending performance and welding performance The P235GH presure vessel plate and sheets size, shape and allowable deviation of the steel plate should meet the requirements of EN10028-1 2007 + A1: 2009,S355J0 carbon steel material.S355J0 carbon steel material,Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the International leading steel materials supplier.S355J0 carbon steel material,Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process They need to be heated to 1100 ° C to 1250 ° C for rolling This rolling process is called hot rolling Rolling at room temperature is generally understood as cold rolling However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling,S355J0 carbon steel material.The primary purpose of adding alloy elements into steel is to improve the hardenability of steel and to ensure that martensite can be easily obtained during quenching. The second is to improve the tempering stability of the steel, to keep the martensite at a higher temperature, so that the carbide precipitated in the tempered steel is finer, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel. One of the main purposes of adding alloy elements is to improve the strength of steel.The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
