The tensile strength can be by a tempering of steel at 330-370 ° C (about 4
Hours duration) to approximately 100-300 N / mm² (in relation to the original
Increase in strength of the material).

6. mechanical details
Tensile yield strength RP 0.2: dependent on the tensile strength
Strain A-80: dependent on the tensile strength
After cutting (E.g. by tumbling) are good edge processing
following values possible:
Alternating bending (medium voltage = 0):
550 MPa (50% of the test samples are over 2 million cycles at normal
Environment), at a bend perpendicular to the direction of rolling.
Threshold tensile (minimum load = 0):
420 MPa (50% of the test samples are over 2 million cycles at normal
Environment), at a bend perpendicular to the rolling direction
Since the bending fatigue strength of various factors such as the
Depends on environmental conditions and the edge quality cannot
Values are guaranteed.
During heavy load or bends that are not perpendicular to the rolling direction,
requires the use of hardened steel as the material 1.4031 mo.
The highest application temperature is between 120 depending on the load and
250 ° C (cf. DIN 17224? Spring band made of stainless steel). Please note,
that the values for the modulus of elasticity with increasing temperature drop.
