 Detailed Introduction to AS3678-250 Steel Plate

AS3678-250 steel plate is a widely used structural carbon steel grade that complies with the Australian/New Zealand standard AS/NZS 3678. This standard defines the technical specifications for hot-rolled structural steel plates, and the "250" in AS3678-250 indicates a minimum yield strength of 250 MPa. Manufactured through a thermomechanical rolling process, this steel grade is equivalent to the Chinese Q235B steel, making it a versatile and cost-effective option for various construction and engineering applications.

AS3678-250 is renowned for its excellent balance of strength, ductility, and weldability, making it suitable for general fabrication, structural members, bridges, high-rise buildings, and storage tanks. Its low carbon content ensures good cold-forming performance and weldability, while the addition of manganese and other trace alloying elements enhances its mechanical properties. Depending on specific requirements, AS3678-250 can be delivered in various states, including hot-rolled, normalized, tempered, or quenched and tempered, to meet diverse project needs.

The steel plate’s chemical composition and mechanical properties are carefully controlled to meet the AS/NZS 3678 standard, ensuring reliability and consistency in performance. Below are detailed tables outlining its chemical composition and mechanical properties.

 Chemical Composition of AS3678-250 Steel Plate  
(Melting Analysis, Maximum Values Unless Specified Otherwise)

| Element       | C    | Si   | Mn   | P     | S     | Al   | Ti   | Cu   |
|---------------|------|------|------|-------|-------|------|------|------|
| Content (%)   | ≤0.22| ≤0.55| ≤1.70| ≤0.040| ≤0.040| ≤0.10| ≤0.04| ≤0.40|

**Notes:**
1. To improve specific properties, trace amounts of other alloying elements may be added, as permitted by the standard.
2. The allowable deviation of the chemical composition complies with GB/T222 or equivalent standards.
