ISO 7438 Bend Test for Metallic Materials
ISO 7438 is the International Standard for bend testing of metallic materials, checking whether a metal can undergo plastic deformation in bending without cracking. To match this to your program, talk with our team.
What ISO 7438 Covers
It bends a specimen through a defined angle around a former of specified diameter and assesses the outer surface for cracks, giving a simple pass or fail measure of ductility and soundness.
How the Test Is Run
A specimen is bent around a mandrel to a set angle in a bend fixture, then the tension surface is examined for cracking. The result confirms the metal meets the required bendability.
Why It Matters
Bend testing is a quick, widely specified ductility check for sheet, plate, and bar; a rigid bend fixture and controlled former diameter are essential.
