Shear Modulus in GPa (Gigapascal) at room temperature (guide value) according ISO 6931-1 table A.1 (excerpt for material X10CrNi18-8)

Intermediate values can be averaged. 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 MP = 1 N/mm².
