SM570 is a high-strength steel grade specified in the JIS G3106 standard, primarily used in structural applications. It has good weldability and toughness, making it suitable for building structures, bridges, and general construction.
Equivalent Grades to SM570
SM570 steel is often compared to other high-strength structural steels used globally. Some commonly referenced equivalents include:
EN Standard:
S355J2 or S355K2 (with additional toughness requirements for certain applications)
ASTM Standard:
ASTM A572 Grade 50 or Grade 65 (though these grades may differ slightly in mechanical properties)
Chinese Standard:
Q460C or Q460D (based on comparable yield and tensile strength)
Other Regional Standards:
DIN StE460 (German DIN standard)
BS4360 Grade 50D (older British standard)
Key Mechanical Properties of SM570
Yield Strength: ≥ 460 MPa
Tensile Strength: 570-720 MPa
Elongation: 17% (minimum, depending on thickness)
Always confirm specific applications with the project requirements and relevant standards to ensure accurate equivalence and compatibility.
