ISO 10275: Tensile strain hardening exponent (n-value) for metal sheet and strip
ISO 10275 defines how to determine the tensile strain-hardening exponent, the n-value, for flat metallic products from tensile stress-strain data. To match a setup to this test, talk with our team.
What ISO 10275 Covers
The n-value quantifies how a flat metal work-hardens through the uniform plastic range, a key indicator of formability for stamping and deep drawing. It is extracted by fitting the plastic region of the tensile curve.
Reading the Designation
Cited as ISO 10275:YYYY. Confirm the edition and the strain range for the fit.
How the Value Is Obtained
A tensile test is run on a flat specimen, and the uniform plastic portion of the true stress-strain data is fitted to a power law to obtain n. Accurate strain measurement across the fitting range is required.
Preparing Specimens
Flat specimens with accurate width and clean edges keep the fit reliable. To configure a system for n-value testing, request a quote.
