SM490B is a Japanese standard low alloy steel plate, JISG3106 standard. It is a structural steel produced according to the Japanese standard JIS G3106, with a strength of 490MPa. It is mainly used in buildings, Bridges, ships, rail vehicles, oil storage tanks, containers and other buildings requiring advanced weldability.

B: Indicates the impact toughness grade of this material. For SN490B, it usually refers to the impact toughness requirement at -20 ° C (-4 ° F). This means that the alloy plate of SN490B can still maintain good impact toughness at lower temperatures.

Similar to SN490B, but class C generally indicates the material's impact toughness requirements at -40 ° C (-40 ° F). The alloy plates of SN490C are suitable for structures that need to work at extremely low temperatures, such as polar buildings, Bridges in cold regions, etc.

At present, SN steel is mainly used in housing structures, factories, stations and other buildings, buildings and large buildings have been widely used, the use of grade SN490B or C, such as the Yunlin high-speed railway under construction, SN490B, C series steel. However, SN400 series steel is used for the low layer. It is mainly used for rolling all kinds of steel, steel plate, steel pipe and steel bar, widely used in steel structure and reinforced concrete structure, especially suitable for all kinds of heavy structure, high-rise structure, long-span structure and bridge engineering. It is used in special steel structures, such as steel chimneys, steel towers, monumental buildings (China Millennium Monument in Beijing), urban large sculptures (Giant Buddha in the South China Sea), high-voltage transmission towers, microwave stations, radar stations, rocket launch towers, offshore oil platforms.
