ASK:
ANSWER: JIS G 3101 steel specification is the hot rolled carbon steels to be used for bridges ships,rolling stocks, petroleum storage tanks containers and other constructions that are required superiority in weldability.
The applicable thickness of SM490C steel strip is not more than 100mm (steel plates, steel strip, section steel). not more than 50mm ( flat bar)
SM490C steel delivery under steel plates, steel strip, section steel and flat steel condition.
SM490C hot rolled steel for welded structural use is under the Japanese standard JIS G 3106. The Carbon chemical composition of SM490C in standard is not more than 0.18%. Carbon equivalent Of SM490C is ≤0.38% (≤50mm); ≤0.40% (above 50mm-100mm)
The Elongation rate of SM490C is above 17%, Yield strength is above 295MPa, tensile strength is 490-610MPa. SM490C has impact test under 0 degree and the energy is above 47J.
