JIS G3106 is the Japanese Industrial Standard for rolled steel for welded structures.
JIS G3106 SM490A SM490B SM490C AM490YA Chemical Composition and Technical Property is as below:
Standard | C % max | Si max | Mn max | P max | S max | Cr max | Ni max | Cu max | tensile strength（MPa） | yield strength（MPa） | Elongation% |
SM490A | 0.2 | 0.55 | 1.65 | 0.035 | 0.035 | - | - | - | 490-610 | ≥275 | ≥21 |
SM490B | 0.2 | 0.55 | 1.65 | 0.035 | 0.035 | - | - | - | 490-610 | ≥275 | ≥17 |

SM490A, SM490B, SM490C and SM490YA/YB under JIS G3106 are different grades of rolled steel for welded structures, among which SM490YA/YB is known as super-heavy welded structural steel.
The following are the areas of application of JIS G3106 SM490A SM490B SM490C AM490YA:
SM490A: Used for structural components in external engineering, ships, military (armoured) buildings, etc.
SM490B: Commonly used for cutting machinery and equipment parts, large welded steel structures, large buildings such as warehouses and factories, waiting halls, also applied to bridge structures, large exhibitions and high-rise building structures.
SM490C: Similar to SM490A and SM490B, it is used for bridges, ships, vehicles, petroleum storage tanks, containers and other structures that require superior weldability.
SM490YA: Steel for super-heavy welded structures, especially for bridges, motorway construction and other more demanding structures.
