GB/T 16270 standard specifies technical requirements for high-strength structural steel plates
delivered in a quenched and tempered condition. It was developed to align Chinese production with international standards like EN 10025-6 ISO 4950.3 Key Versions and Evolution GB/T 16270-1996:
The original version applicable to steel plates and strips up to 100mm thick with yield strengths between 420MPa and 690MPa. GB/T 16270-2009:
The current active version. Major changes from the 1996 edition include: Scope Change: Applicable thickness extended from 100mm to ; steel strips were removed from the scope. New Grades: Added ultra-high-strength grades Q800, Q890, and Q960 Quality Grades: Added quality grades
(except for Q460) to classify performance at varying impact temperatures. Chinese Standard GB/T Technical Specifications Delivery Condition: Specifically requires quenched and tempered (Q+T) processing to achieve high yield strength and toughness. Dimensions & Weight:
Steel plate dimensions and allowable deviations must comply with the general standard Composition:
Refined through oxygen converter or electro-smelting. It utilizes micro-alloying elements like Niobium (Nb), Vanadium (V), and Titanium (Ti) to refine grain size and enhance strength. Mechanical Properties:
Steel is tested for yield strength, tensile strength, elongation, and impact energy. For example, must maintain specific impact toughness at Chinese Standard GB/T Common Steel Grades gb t 16270 pdf
The grades are named based on their minimum yield strength (in MPa): Detail of GB/T 16270-2009 - Code of China
