Phosphorus (P) and Sulfur (S) are strictly limited to prevent embrittlement. Mechanical Properties
Example:
The is more than just a file; it is a critical tool for anyone sourcing, designing, or fabricating high-strength quenched and tempered steel for the Chinese market or from Chinese mills.
The most common grades detailed within the GB/T 16270 PDF include: : Minimum yield strength of 460 MPa. Q500 : Minimum yield strength of 500 MPa. Q550 : Minimum yield strength of 550 MPa. Q620 : Minimum yield strength of 620 MPa. Q690 : Minimum yield strength of 690 MPa. Q890 : Minimum yield strength of 890 MPa. Q960 : Minimum yield strength of 960 MPa. Quality Series (A to F)
: It specifies inspection rules, including ultrasonic testing (referenced in GB/T 2970) and Charpy V-Notch impact tests.
Understanding GB/T 16270: The Standard for High-Strength Structural Steel
If you need:
This standard ensures that steel plates used in high-stress environments possess an optimal balance of extreme tensile strength, impact toughness, and weldability. Key Steel Grades Covered in the Standard
: Steel grades are named using three parts: the letter " Q " (representing yield strength), a numerical value for the minimum yield strength (e.g., 460, 690, 960), and a quality grade (C, D, E, or F) .
: Grade names start with "Q" (for qufu , meaning yield), followed by the minimum yield strength (e.g., Q690) and a quality grade letter (C, D, E, or F) indicating impact testing temperature.
: There are several databases and services that offer access to standards from various countries, often for a fee. Examples include IHS Standards Connect, ANSI Webstore, and ISO Online Library, though they might not specifically have GB/T 16270.
Represents the minimum yield strength (e.g., 460, 500, 550, 620, 690, 890).
If you need the official document for certification or legal purposes, downloading a random PDF from a search engine can be risky (malware or outdated versions). Here are reliable sources:
Where high-strength steel is required to handle pressure without excessive weight. 4. GB/T 16270-2009 PDF Download and Access
While these standards are similar, engineers must always cross-reference the exact chemical limits and impact testing temperatures in the PDF to verify that a substitute material meets specific application tolerances. Common Applications of GB/T 16270 Steel Plates
| Grade | Yield Strength (MPa) Min | Tensile Strength (MPa) | Elongation (%) Min | | :--- | :--- | :--- | :--- | | | 460 | 550 - 720 | 17 | | Q500 | 500 | 590 - 770 | 17 | | Q550 | 550 | 670 - 830 | 16 | | Q620 | 620 | 710 - 880 | 15 | | Q690 | 690 | 770 - 940 | 14 |
Each grade is further divided into quality sub-grades (C, D, E, F) based on Charpy V-notch impact testing temperatures: Impact test at 0°C. D: Impact test at -20°C. E: Impact test at -40°C. F: Impact test at -60°C.
