The SM490 material from the Japanese Industrial Standards (JIS G3106) is often compared to certain grades in the ASTM standards, but direct equivalence depends on the specific properties and intended use. The most commonly cited ASTM equivalents for SM490 are:
Possible ASTM Equivalents:
ASTM A572 Grade 50
This is a high-strength, low-alloy structural steel grade with a yield strength of 50 ksi (approximately 345 MPa) and good weldability.
While the yield strength of ASTM A572 Grade 50 is slightly lower than SM490 (490 MPa), it is often considered equivalent for certain applications.
ASTM A992
Primarily used for structural shapes in construction, A992 offers a yield strength of 345 MPa and good weldability. It is similar to SM490 for structural applications but has different chemical requirements.
Key Comparisons
Note:
While SM490 and ASTM A572/A992 may be used interchangeably in some cases, careful evaluation of the mechanical properties, chemical composition, and application requirements is necessary.
If you're working on international projects, consult a metallurgical expert or engineer to ensure compliance with local standards.
