Hi Bob,
You are right about the plug-and-chug mindset -- the bane of learning anything! My class includes a thorough introduction to the science of the Fe-C system and the effects of different elements on hardenability, strength and toughness. Once they get that, I would like some means of showing them general trends that they can play with, rather than only look at the hardenability curves in handbooks, or the plots of strength vs C wt% for different tempering temperatures. I teach out of the handbooks anyway so they learn to use them, but a little variety helps.
Thanks everyone!
Harold

It is inevitable that students and other users want to punch in a chemistry and magically everything you might want to know magically appears - like hardness, tensile properties, etc. However the output is only as good as the source data and the algorithms that are used to do the calculations. It would appear that the Ovako system may be based on ASTM A255 which was created by using a very large regression analysis (originally by Caterpillar). It would help if the source data was clearly identified for whichever system is used.
I would hope that these calculators were only introduced to students after suitable explanations of hardenability and what it means - ie the classic definitions as well as the individual effects of elemental additions on the phase diagram and contributions to hardenability.

For undergraduate teaching purposes, I've been looking at Ovako's Steel Calculator – it is free, but I would not endeavor to use it for commercial purposes since I have no information about how well vetted it is:

Jim,
I recently installed SteCal 3.0 on a 64-bit Windows 10 machine, and it seems to work fine. I updated the page in the ASM store to reflect this.
The SteCal 3.0 manual is attached for those who may be interested in learning more about software. SteCal was created by Professor Pascual Tarin possibly in the 1980s) and he published three versions over time with ASM.
The user interface is showing its age, but is still functional. ASM has had some discussions about creating an online version of the software. We are interested in feedback about the general capabilities of the software and potential enhancements.

Neda and co -
Does anyone know if SteCal software will be upgraded
for Windows 10 and 11?
thanks and regards,

***********************************************************************************
SteCal 3.0 is a program for predicting the properties obtained from
heat treating low-alloy steels. Available for the first time in user-
friendly Microsoft Windows format, SteCal calculates the parameters
and behavioral properties representative of low-alloy steels, and
predicts the effects of heat treating such steels. It is an excellent
tool for heat treaters to use in estimating and refining heat treating
parameters for unfamiliar steels. SteCal is also useful for comparing
the properties of two steels of different composition, which can help
to suggest the most appropriate composition for a particular application.
SteCal is based on the most effective and precise heat treating
calculation routines available. It can be used to predict heat
treating data such as lower critical temperature, critical point
of heating, highest feasible tempering temperature, austenitizing
temperature, susceptibility to quench cracking, and hardness obtained
from various treatments. The program can be used to generate CT diagrams,
IT diagrams, hardness versus tempering curves (with calculated tensile
strength, yield strength, and elongation values), and Jominy end-quench
hardenability curves. Data can be viewed as graphs or tables.
SteCal 3.0 is compatible with Windows XP and Windows 7.

Hello all,
I appreciate it if you share any experience that you've had with SteCal software. What are the weaknesses and strengths of this software?
Thanks,
