Bending strength value of Stainless steel grade 304 ~600 MPa

It is better to find it by bend test. Depending upon your boundary conditions, sections of the beam this can vary.  Because we bending stress is (M*y/I). Where, M is bending moment, 'y' is the distance from neutral axis of the c/s and 'I' is 2nd moment of area.

The recomended value for bending strength is to consider two times the yield tensile strength. According to www.matweb.com for this material can be as 400MPa.

Thanks to all for your valuable inputs.
