GB/T 6396-2026Clad steel plates — Mechanical and technological tests (English PDF)

Foreword

This document conforms to GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents".

This document replaces GB/T 6396-2008 "Test Methods for Mechanical and Technological Properties of Composite Steel Plates". Compared with GB/T 6396-2008, Apart from structural adjustments and editorial changes, the main technical changes are as follows.

--The scope of this document has been changed (see Chapter 1, Chapter 1 of the 2008 edition);

--The definitions of the terms "external bending test," "internal bending test," and "lateral bending test" have been changed, and the term "composite interface" has been added.

Definitions (see 3.5, 3.10, 3.11, 3.12, and 3.9, 3.10, 3.11 in the 2008 edition);

--The description of symbol F has been changed, and symbols d3, d4, d5, d6, H, L, and R have been added. The definition of ln has also been expanded to "n=1, 2, k" (see [link to documentation]).

--Added a requirement for sample width when the total thickness T of the composite steel plate is greater than 40 mm (see 8.2.3);

1 Scope

This document specifies the tensile, shear, bending, bonding, adhesion, impact, and other properties of single-sided and double-sided composite steel sheets (hereinafter referred to as composite steel sheets). Vickers hardness test method.

This document applies to rolling, explosive welding, and explosive rolling processes using carbon steel plates as the base material and stainless steel or non-ferrous metals and alloys as the cladding material.

Mechanical and technological properties of composite steel plates manufactured by methods such as fabrication, welding and rolling.

Other metal composite panels should be handled in accordance with this document.
