If such is the case, more than one value of the strain-hardening exponent may be obtained 2 by agreement using this test method. Practically, it provides an empirical parameter for appraising the relative stretch formability of similar metallic systems. The strain-hardening exponent is also a e466 of the increase in strength of a material due to plastic deformation.

The value of the strain-hardening exponent, nhas no units and is independent of the units used in its determination. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity astj, furnaces, baths and custom solutions for unique applications. ASTM E is for metallic sheet materials with thicknesses of at least 0. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models.

ASTM E Tensile Strain-Hardening Exponents (n -Values) of Metallic Sheet Materials

Measures displacement for axial tensile, compression, and cyclic testing Gage lengths from 10 mm to 50 mm 0. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

By means of our tensile testing expertise and modular product design, we will help find the solution that is right for you.

E Clip On Axial Extensometer.

We are confident that we have what you are looking for. ASTM E covers the determination of a strainhardening exponent by tension testing of metallic sheet materials for which plastic-flow behavior obeys the power curve given in the Introduction.

A single power curve may not be a satisfactory fit to the entire stress-strain curve between yield and necking. Caution should be observed in the use zstm curve-smoothing techniques as they may affect the n -value.
