Reduction of Tensile Strength with PWHT
Reduction of Tensile Strength with PWHT
(OP)
I am in need of some data for predicting the reduction of tensile strength in 2.5" thick SA516-70 normalized at varying PWHT times. I have read on some threads about the Hollomon-Jaffee Parameter, but I haven't had any experience with this equation. Can someone help me out?

I knew you would be along soon enough. That second .PDF is great. But on page 2, it refers to a "Plate Steel Specification Guide" with a link that doesn't go anywhere. If you get in to www.mittalsteel.com or the ArcelorMittal website there isn't any way to get Mittal technical publications. Can you help us find that Guide?

The time/temperature effects on tempering can be described using either LM for strength or HJ for hardness because these parametric equations provide the best correlation to plotted data.
