SM490Y H section steel
SM490Y is a specific grade within the SM490 family of steels outlined in the JIS G3106 standard. The "SM" indicates that it is a structural steel, and "490" refers to the minimum yield strength of the steel in megapascals (MPa). The addition of "Y" to SM490Y indicates that this grade has improved Charpy impact properties compared to other SM490 variants. Charpy impact testing measures a material's resistance to fracture under impact loading conditions.

Here are the key features and details of SM490Y H shaped steel:
Improved Impact Properties: SM490Y is known for its improved Charpy impact properties compared to other SM490 variants. This makes it particularly suitable for applications where resistance to brittle fracture under impact loading is important, such as in structures subjected to seismic forces or dynamic loads.
Yield Strength: The yield strength of SM490Y steel can vary, but it generally falls within the range of 355 to 490 MPa. This range indicates the stress level at which the material begins to deform permanently.
Applications: SM490Y H-shaped steel beams are used in various structural applications, including building frames, bridges, industrial structures, and other construction projects where impact resistance and structural stability are required.
