2015-12-18 MECHANICAL CHANGES:

I assume you are referring to the tensile properties of bars machined to different diameters. As long as your bars have a uniform microstructure in the radial direction (NO surface decarburization/carburization/intergranualar

2015-05-18 heat treatment:

Annealing in general may be used to describe thermal treatment processes.     In steels, full annealing, sometimes simply referred to as annealing, is a term used to describe the heat treatment resulting

2015-03-25 Stress relief of 17-4 Condition H1150:

As you are assuming, a stress relief operation at a 1050 F subsequent to aging at 1150 F will not make your rings H1050-treated. The reason is that the copper precipitates formed and somewhat coasened

2014-09-11 17-4 PH H900:

There are two things to consider before making a decision. Hardness which affects the machinability is lower in the solution annealed condition, namely after annealing at around 1900 F, than in the H900

2013-11-05 Annealing of 316 SST:

The desired properties will be achieved by slight increase of the testing temperature, for instance raising the temperature from room temperature to between 50-100 degrees Celsius. If this is not allowed
