SS490 Steel Description

SS490 carbon structural steel belongs to Japanese standard: JIS G3101 rolled steel for general structure, equivalent to national standard Q275. SS490 structural steel mainly guarantees mechanical properties, has high strength, good plasticity and machinability, and certain welding performance. JIS G3101 SS490 Carbon steel is used to manufacture parts that require high strength, such as gears, shafts, sprockets, keys, Bolts, nuts, sections for agricultural machinery, conveyor chains and links.

The meaning of SS490 carbon and low-alloy structural steel, the first "S" means steel, the second "S" means "structure" (Structure), 490 is the lower limit tensile strength of 490MPa, and the whole represents ordinary structural steel with a tensile strength of 490 MPa . JIS 3101 SS490 steel plate is a low alloy steel under JIS standard, equivalent to DIN17100 St52-3, EN10025 S355JR, BS 50B and UNI7070 Fe510B.
