Phosphorus (P) and Sulfur (S) are strictly limited to prevent embrittlement. Mechanical Properties
: Indicates the Charpy V-Notch impact testing temperature zone. Grade "E" represents a demanding toughness threshold at -40°C. Common Portfolio Variations
Kept relatively low to maintain good weldability.
Because the native standard is written in Chinese, ensure you obtain an official English translation version if your project involves international procurement or cross-border engineering teams. gb t 16270 pdf
Note: The suffix letters (D, E) denote impact test temperatures: D = -20°C, E = -40°C.
: Includes specifications for yield strength, tensile strength, elongation, and Charpy V-notch impact energy at specific temperatures (e.g., 0°C to -60°C). Quality Grades
This differentiates the quality grades (C, D, E). Phosphorus (P) and Sulfur (S) are strictly limited
High-strength structural steel plates and strips: products supplied in the heat-treated or controlled rolled condition
: The applicable maximum thickness of steel plates was extended from 100mm to 150mm .
The official GB/T 16270 PDF can be purchased from the Standardization Administration of China (SAC) or authorized resellers like Chinese Standard Bookstore. Be cautious of free "scanned" copies online, as they may be outdated (check for revision year). Common Portfolio Variations Kept relatively low to maintain
The standard is a critical Chinese national specification governing the technical delivery conditions for high-strength structural steel plates . Primarily used in heavy-duty engineering and construction, this standard ensures that steel plates possess the necessary yield strength, toughness, and weldability for demanding structural applications. Overview of GB/T 16270
The primary active version of this standard is , which officially replaced the older GB/T 16270-1996 edition. The update expanded maximum plate thicknesses and added higher yield strength options. 1. Overview and Core Scope of GB/T 16270
Defines specific requirements for Yield Strength, Tensile Strength, Elongation, and Impact Toughness (often tested at various temperatures, e.g., 0°C, -20°C, or -40°C).
