What is A573 gr 70 equivalent to?

ASTM A573 Grade 70 is a structural carbon steel grade with good notch toughness. It is primarily used for applications requiring improved toughness and reliability in welded structures. Some equivalent materials in various standards are:

European Standard Equivalent:

S355J2 (EN 10025-2): A structural steel with similar mechanical properties, widely used in Europe.

Chinese Standard Equivalent:

Q345D or Q345E: These grades under GB/T 1591 have comparable mechanical and chemical properties, used in structural applications in China.

Japanese Standard Equivalent:

JIS G3106 SM490YB shares similar strength and toughness properties under Japanese standards.

Indian Standard Equivalent:

IS 2062 E350C: Structural steel grade under Indian standards with comparable yield and tensile strength.

These equivalents may vary slightly in chemical composition and testing requirements, so direct substitution should be confirmed based on application requirements.
