Software to predict steel hardenability

Software to predict steel hardenability

Software to predict steel hardenability

(OP)
More years ago than I care to remember I was given a piece of software called 1E38 by Caterpillar.  Plug in the chemical analysis of the steel (within limits) and it would give you predicted Jominy results.  I think I got it legitimately from Caterpillar.

Anyway, it's a bit old now and runs under DOS.

Is there any current software anyone can suggest to do the same thing?

RE: Software to predict steel hardenability

Caterpillar still offers this program designed to run under a more modern OS.  This was a few years ago, but I got a copy of the version by cd-rom.  I think I had to send a blank one in a self addressed stampped envelope, but they sent me their program.

It does have some limitations, in that the regression tables are not listed, nor does it allow you to go beyond their established limits, unless they have changed the program.  

I know in the past that they published the regression equations in the 1E0038 specification.  They made 1E0038 obsolete and combined it with 1E0024.  I don't think they include the regression tables in the newest version, but I could be wrong.  Again I haven't dealt with the specification in a good many years.

Best of luck

Try this online tools from EWI:
Weld Microstructure Prediction
Prediction of Microstructure and Hardness in Low-Alloy Steel Heat-Affected-Zones: The tool calculates the fractions of different ferrite morphology that forms from the austenite and relates the same to Vickers hardness

deadrange & CoryPad,
An e-mail has been sent to Caterpillar so we'll see what happens.  I've also looked up details of SteCal, thank you.

UPDATE

I've got an acknowledgement of my request and am advised that my local Cat dealer in the UK will be contacting me.

Umm.

UPDATE 2

Got e-mail from UK dealer asking for more details about what I was asking for.

RE: Software to predict steel hardenability

Hi
Does anybody know a program that can calculate jominy on SAE4340. My old 1E38 program seems to fail.

RE: Software to predict steel hardenability

Hi PeterCharles

My problem is that it seems that 1E38 does not work on 4340.
Can you make a jominy cal. on 4340?

RE: Software to predict steel hardenability

(OP)
Sorry, misunderstood your problem.  I've only got 1E38 so can't help.

RE: Software to predict steel hardenability

1E38 has a composition limit of 1.50 mass percent Ni, so 4340 is not able to be calculated due to its Ni concentration (1.55 to 2.00 mass percent).  You can use 1.50 for Ni in 4340 with 1E38 and get a lower bound estimate for hardenability.

RE: Software to predict steel hardenability

I will try to do so and estimate my value of Ni 1,75
Hope that my customer approve.

It seem to be difficult to have programs for many diffrent steelgrades when it comes to jominy. Dont really like to make a real test dont think they are good enough.

So if anybody have any program to calc diffrent steelgrades
please let me know.

I do like this forum. First time i have seen it. Is it US or GBR.

RE: Software to predict steel hardenability

The forum members are international, but the site owner is based in the USA.

Still nothing from UK dealer, have asked for an e-mail address in the States

 

RE: Software to predict steel hardenability

Heavyforgings,

    You can go about calculating 4340 Hardenability a couple of ways.  I believe StelCalc works for 43XX grades of steel.  Also if you are able to get your hands on an older copy of the actualy specification from Caterpillar 1E0038, they included their regression equations for each element.  You can then go and calculate the Hardenability of each J point based on the new DI that is created.  
    My understanding is the reason why Caterpillar's program for calculated jominy isn't as good for some alloy compositions is because they don't typically buy a whole bunch of these grades.  The regreassion equations are based on the Grossman tables and with enough data points refined to the program you have in front of you.  However, without enough data points they cannot make the regression better.


PeterCharles:
    Also one last comment.  I believe in 2006/07, I can't remember the exact year, Caterpillar made 1E0038 obsolete.  They combined the specification with 1E0024 their general steel specification.  I am not sure if they have changed the name of the program name.  You may want to contact your UK dealer and ask for a program for 1E0024.

For 4340 hardenability curves, I have used Table A2 contained in SAE J406 which lists nickel up to 2.00%.

RE: Software to predict steel hardenability

dbooker,

Thanks for the info on SAE J406.  I originally checked ASTM A 255 and verified that it is valid only up to 1.5% Ni max, and just assumed that SAE J406 was the same.

RE: Software to predict steel hardenability

Tnx dbooker now i need to get SAE J406 to get these tables because i guess that this is no program?

RE: Software to predict steel hardenability

Heavyforgings,

I did not notice that you already have the link in your earlier post. The text version of J406 is $61 USD.
