4.2.1 Tensile Properties

Properties must meet the minimum values in the transverse direction.

• Yield Strength ($R_eH$): Decreases as plate thickness increases. For example, Q690 requires:
  • Thickness ≤ 16mm: ReH ≥ 690 MPa
  • Thickness 16-50mm: ReH ≥ 650 MPa
  • Thickness > 50mm: ReH ≥ 630 MPa
• Tensile Strength ($R_m$): Typically 1.1 to 1.3 times the yield strength, ensuring adequate elongation capability.
• Elongation ($A$): Usually ranges from 11% to 18%, depending on strength grade. Higher strength usually correlates with lower elongation.

In this comprehensive guide, we will explore everything you need to know about GB/T 16270, how to use the PDF effectively, and how it compares to international equivalents.

2. Mechanical Properties (Table 3)

The PDF provides tension test requirements:

• Yield strength (ReH or Rp0.2)
• Tensile strength (Rm)
• Elongation (A%) – Usually ≥ 14% for most grades.
• Impact absorb energy (KV2) – Minimum values (e.g., 27J or 40J depending on grade).

1. Introduction and Scope

GB/T 16270-2009 is the Chinese national standard specifying the requirements for high-strength structural steel plates supplied in the quenched and tempered (Q&T) condition. This standard replaces the older 1996 version and aligns closely with international standards such as EN 10025-6 (European) and ASTM A514/A517 (American).

The standard applies to steel plates with a nominal thickness ranging from 3mm to 100mm, primarily used for welded structures in construction, mining machinery, cranes, and bridges.

The steel grade designation follows a specific nomenclature: the letter "Q" followed by the specified minimum yield strength value (in MPa), and a quality suffix regarding impact energy.

1. What is GB/T 16270?

GB/T 16270 is a Chinese national standard for:

High-strength structural steel plates produced by quenching and tempering (Q&T)

It covers plates used in:

• Construction machinery
• Bridges, pressure vessels
• Offshore structures
• Heavy-duty welded structures requiring high yield strength

Typical steel grades (examples):
Q460D, Q550D, Q690D, Q890D, Q960D — where the number indicates minimum yield strength (MPa).
