China hot rolled S275JR S275J0 S275J2 S275N S275NL mild carbon steel sheet plate

Among the Chinese hot rolled S275 series low-carbon steel plates, S275JR steel is the most basic model widely used in building structures; S275J0/J2 has undergone special aging treatment and has better low-temperature toughness, making it suitable for engineering in extremely cold regions.

S275N/NL carbon steel sheet plate needs to undergo normalizing heat treatment to achieve more uniform grain size, and is mainly used for key load-bearing components such as wind power and bridges. The NL grade has passed the -50℃ impact test and meets polar environmental standards.

At present, domestic steel mills can produce S275JR/J0 steel sheet in bulk, but S275J2/NL steel plate needs to be scheduled according to orders, with a longer delivery cycle. End users need to confirm the quality assurance certificate and inspection report in advance when purchasing.
