: Phosphorus and Sulfur are kept strictly low (often under 0.020% or 0.015% for premium grades) to maximize internal cleanliness and prevent tearing. Mechanical Property Requirements For a standard plate thickness (typically ≤50is less than or equal to 50 mm), the steel must hit these benchmark metrics: Steel Grade Min. Yield Strength (MPa) Tensile Strength (MPa) Min. Elongation (%) Q460 550 – 720 Q550 670 – 830 Q690 770 – 940 Q890 940 – 1180 Q960 980 – 1150 Typical Industrial Applications
The 2009 revision introduced several significant changes:
: Depending on the grade, equivalents can be found in ASTM A514 (for high-yield structural plates) or ASTM A709 Grade HPS 100W . Finding and Using the GB/T 16270 PDF
The Standardization Administration of China offers official lookups. gb t 16270 pdf
The standard uses a clear alphanumeric naming system: Q + [yield strength in MPa] + [quality grade letter] .
The current valid version, , was implemented on April 1, 2010, replacing the older 1996 version. It specifies the designations, dimensions, technical requirements, and testing methods for steel plates with a thickness of up to 150mm .
Steels produced under GB/T 16270 are the backbone of modern heavy industry. Their high strength-to-weight ratio makes them indispensable in applications where weight reduction is critical without sacrificing performance. : Phosphorus and Sulfur are kept strictly low (often under 0
