Tensile testing method for wide plates of metallic materials

1 Scope

GB/T 46590-2025 is the Chinese national standard covering the wide plate tensile test - a specimen broad enough to develop plane strain across its width rather than necking freely, which is the condition a real pipeline or pressure vessel wall is in, with the gripping, the instrumentation and the interpretation. First edition, under the China Iron and Steel Association. In force from 1 May 2026. Issued on 31 October 2025, it has been in force since 1 May 2026.

This document specifies the principles, specimens, testing equipment, testing procedures, and test reports for tensile testing of wide plates of metallic materials. This document applies to the determination of uniaxial tensile properties of wide plate tensile specimens of metal sheets or tubes, and is also applicable to the above-mentioned specimens containing specific defects. The deformation and fracture properties of the sample were determined.
