JIS G3106 SM490C carbon steel plate

SM490C material JIS G3106-2008 standard is a hot rolled structural steel. Its minimum yield strength is 325MPa when thickness less than 16mm. SM490C carbon steel plate/sheet is used for the structure part with high requirement of mechanical property and welding performance in building, bridge, ship, oil storage container and construction vehicles.
