High Strength Structural Steel Plates in the Quenched and Tempered Condition
The standard was notably revised (replacing the older 1996 version) to align closely with international benchmarks like the European EN 10025-6 and ISO 4950.3 standards. Typical Applications and Industries

GB/T 16270 is a Chinese national standard ( Guobiao ) that specifies the technical delivery conditions for in the quenched and tempered (Q&T) condition. gb t 16270 pdf
The represents China’s national recommended standard for high-strength structural steel plates in the quenched and tempered condition . Formulated by the China Iron and Steel Association , this specification establishes parameters for chemical composition, dimensions, and testing for materials up to 150mm thick.
This process results in a steel plate with an excellent combination of high strength, good plasticity, and toughness, as well as superior weldability and formability . This combination is essential for demanding structural applications where both high load-bearing capacity and resistance to impact are required.
Significantly higher than standard structural steels, providing safety margins against catastrophic failure. High Strength Structural Steel Plates in the Quenched
Steel grades under this standard follow a specific alphanumeric naming convention: GB/T 16270-2009 English PDF
: Read through the standard to understand its requirements, recommendations, testing methods, and any other specified criteria.
International projects often require swapping GB/T 16270 grades with equivalent regional standards.

If you are sourcing or downloading a formal GB/T 16270 PDF specification document, ensure that you obtain the released by the Standardization Administration of China (SAC). Official revisions occasionally adjust chemical thresholds, maximum plate thickness limits, or testing methodologies to align with modern metallurgical capabilities.
The designation refers to a critical Chinese national standard for the technical delivery conditions of high-strength alloy structural steel plates. Specifically, it covers steels that are delivered in the quenched and tempered (Q&T) condition. Industries globally use this standard to source robust steel capable of withstanding extreme structural loads.
When reviewing the technical parameters inside the standard, buyers and engineers must focus on several core metrics:
For example, a steel plate (often supplied by distributors in the Moscow region) has a minimum yield strength of 690 MPa. Technical Delivery Conditions
