ANSWER: SN490C is the material in Japanese standard JIS G 3136. JIS G 3136 is the Japanese standard specifies the hot rolled steel for building structure.
JIS G 3136 SN490C steel strip,plates,sections and flats applicable thickness is 16 or over to include 100mm.
SN490C is the hot rolled steel material to be used for welded gas cylinder. SN490C gas cylinder material steel C chemical composition is max 0.20%
The heat treatment of SN490C are : Normalized (N), Tempered (T), Thermomechanically control processed (TMC)
JIS G 3136 SN490C hot rolled structural steel mechanical property is : Yield strength min 325MPa and tensile strength min 490-610MPa, Elongation in 80mm min 17%
SN490C steel can be produced as steel sheet, steel plates, steel coil, steel strip ,section and so on
