Anybody uses 4130 steel
Tim,
4130 steel is for case hardening. In it's soft state it can be used for
anything in a model locomotive where a steel component is needed.

Anybody uses 4130 steel as used in the aircraft industry? I do and find it
just about the best for our uses. not cheap but..Also available in many
sizes.

Actually, it probably will. The self-cleaning feature on ovens made in the past 20
years
or so raises the temp to 900F (482C), which should be sufficient.
Arthur mentioned bedding in
Oooops um yea 400C is more like it, sorry.

We have some 900C+ annealers at work... though I don't think they'd let me
try putting a piece of mild steel in with a wafer. *devious grin*

Dear Jon,
Excuse me but I have to correct you on your concept of
correcting/controlling warpage when machining steel or machining just about
any other metal. T

Terry,
I can't recall the temperature but my understanding is that steel must
be taken beyond to its critical temperature, at which point
I had been wondering about annealing the CRS. Isn't simply a case of heating it to
like 400 degrees F and holding it for an hour per 1/2 inch, then allowing to cool
slowly? Since we are working with fairly short pieces that's something that could be
done in the home oven (while the "boss" is awa
I've used 304 s.s. for laser cut frames (1/8") recently and not noticed any
warpage after cutting axle box slots. Laser cut connecting rods (1/8")have
been slightly warped but I attribute that to heat generated during the
cutting process. In any case, the slight warpage was easily straightened,

Bert,
Yes, it's one of the basic materials in the U.S. sheet metal industry
although I now see steel without scale occasionally laying behind the
shears

This is as accurate a description and examples of the problems with CRS
as I have heard lately. Obviously it has it place and uses, otherwise they
wouldn't make the stuff, but one has to know how
Hi Group,
Regarding the warpage of cold rolled steels...
I learned this in Machine Tool Tech school years ago, and I'll relate my
crude understanding as best I can: When cold rolled metals are rolled out
into sheets, stresses are created on the surfaces which are greater than the
internal stresse
To all interested
While on this subject of using steel if there is any sharp
bending to be done it could be of some advantage to know the rolling
direction of the plate. Sharp bends 90° to the rolling direction can
cause fractures of the steel. Particularly on harder sorts. Whereas
bending across
