I'm looking for fatigue material data

[Klaus800]

I'm looking for the two steel grades A283C and A572Gr50C (in Germany S235 and S355)the following parameters for the lifetime calculations (FEM calculations of Fatigue/Durability with Siemens NX)

Fatigue Strength Coefficient
Fatigue Strength Exponent
Fatigue Ductility Coefficient
Fatigue Ductility Exponent
Cyclic Strength Coefficient
Cyclic Strain Hardening Exponent

Many thanks for your help and many greetings
Klaus

have you tried

http://www.matweb.com?

not sure if it would have all the variables you need

eta:

the german spec comes back with A284C
