Cold rolled steel plate and SM490C grade steel sheet

GB / T1591 Q345D steel is a commonly used low alloy plate in China. It is equivalent to grade S355J2 in Germany and ASTM A529MGr50 in the United States, with slightly different chemical composition and the same mechanical properties. Under normal delivery conditions, , Q345D steel equivalent to S355J2G3 in European standard, and even almost the same performance as the S355J2G4. They can be used interchangeably.
