E Modulus / Shear Modulus

E Modulus in GPa (Gigapascal) at room temperature (guide value)
  condition of the wire
tensile strength in MPa (Megapascal) delivery condition + heat treatment
approx. 1800 180 195
approx. 1300 174 189

 

 

Shear Modulus in GPa (Gigapascal) at room temperature (guide value)

Interim values can be mediated. With rising temperatures the levels of E modulus and shear modulus decline. The specifications for the shear modulus apply to measurement with a torsion pendulum at wires with max. 2,8 mm diameter. The E-modulus is calculated from the shear modulus with the poissons constant of 0,30. 1 Pascal = 1 N/m2
