Re: Stainless Steel Prop.

[Subject Prev][Subject Next][Thread Prev][Thread Next]
A few items if using stainless steels as a structural load carrying member:

The modulus of elasticity (E) is taken as 28,000 ksi for stainless steels.

Stainless steels do not exhibit a linear stress-strain relationship between
zero stress and yield stress.  Therefore the yield stress is determined by
an offset method.  The strain at yield stress is not the yield stress
divided by E; it is much more than that.

AISC specification equations are calibrated to stress-strain curves for
carbon steels which exhibit a linear stress strain relationship from zero
stress to the proportional limit (the yield stress).  Use of AISC
specification equations for stainless steel require caution to make sure
that the larger strains do not affect expected behavior.

Does anyone know the yield strength of A304 and A316 stainless steel?
