SM400B STEEL PLATE

SM400B,SM400B steel plate,SM400B steel sheet is Under Janpanese steel standard JIS G3106,SM400 has three different grades,aush as SM400A,SM400B and SM400C,the main difference is the carbon contains for these steel grades.Comparing with SM400B,steel plate SM400C have to be done low temperature impacting test under 0 centigrade with the minimum impact energy value at 47J,SM400B with 27J for the sample test plate.If the end users need do heat treatment for structural steel plate SM400B under Normalized,Quenched and Tempered,Tempered,they should issued this term in PO when ordered.
