What are the consequences of equalizing H13 too long when ramping up to the austenitizing temperature? Standard procedure is to heat to 700 C, equalize for 15 min, then up to 850 C, equalize for 15 min, and then ramp up to the austenitizing temperature of 1030 C. Thanks to some problems with the...
Does anyone know of a diagram showing the effect of carbon content in martensitic stainless steels with approx 12 % Cr? Ideally I'd like to find diagrams for a series of tempering temperatures but at this point I'd be delighted to find anything.
In case anyone is interested, the background...
I'm looking for advice from someone who has experience with 4140 castings or similar.
The intent is to produce a cylindrical part whose largest diameter is 3.5 " Service temperatures are anticipated to range from -30 F to 100 F.
Desired yield strength is 60-70 ksi, desired impact energy is 65...
Does anyone know the origin and use of the Guillet Zinc equivalent factor? I am dealing with a dezincification issue and both the Zn-content and whether the alloy is alpha or alpha + beta are relevant. I have the impression that it is only applicable to the high tensile brasses, but do not...
