JIS G3106 Steel Plate
JIS G3106 Steel Plate
JIS G3106 specification is for hot rolled carbon steel plate for welded structrual purposes, steel grades include: SM400A/B/C, SM490A/B/C, SM490YA/YB, SM520B/C,SM570.
Appication:
SM400A/B/C: Carbon steel shapes, plates, and bars of structural quality for use in riveted, bolted, or welded construction of bridges and buildings, and for general structural purposes.
SM490A/B/C: Hot rolled steel plate used for outside engineering, ships, military (armored) construction.
SM490YA/YB: Super heavy steel plate for welded structure of bridges, highway construction.
SM520B/C: Super heavy steel plate for welded structure, it is also low carbon high strength structural steel with good cold forming property.
SM570: Low alloy and high strength steel plate, heavy and wide plate for machinery parts, boom, crane, chassis, buildings bridges and mobile equipment.JIS G3106 Chemical Composition:
