S275J2 carbon steel plate sheet has good weldability

Q420FT is a kind of steel plate for wind power tower, and its trademarks are Q420FTC, Q420FTD, Q420FTE AND Q420FTF. When the S275J2 carbon steel plate sheet, Q420FT steel plate is required to have the function of thickness direction, other symbols Z15, Z25 and Z35 representing the function level of thickness direction shall be added after the trademark of the above rules.

S275J2 carbon steel plate sheet, Hot-rolled steel coils are made of steel billets, which are made into strip steel by the rough rolling mill and the finishing mill after heating. The hr steel strip from the rolling mill behind the finishing rolling is cooled to a set temperature by laminar flow, and then coiled into a steel coil by the coiler. The cooled steel coil will undergo different processes according to the different needs of users, and is processed into steel plates, flat coils and slit steel strip products.
