Forging and Rolling Temperature

08/10/2018 12:03 AM

Does carbon percentage in steel effects the forging and hot rolling temperatures?

This site does not give any information on the "effect"

Then compare the properties yourself, as the carbon percentage varies. All you need is a good machinist's handbook Mildred.

An absolute perfect answer to the question in one word!! Awesome.

Today there are so many resources on the internet, it seems that some people are getting dumber as the information on the internet explodes.

I learned (from a BOOK) in Junior High School (age 12) about carbon and its' effects on steel. I still have the center punch I made in metal shop. 8 sided high carbon steel bar turned to a point, heat treated and annealed to perfection... I still use it (41 years later) and am using it right now on a wooden toy / treasure chest I am building for my Grandson.

One of the first things you learn in metal shop is how the percentage of carbon and other alloys affect the base metal / steel.

I loved turning 1013 leaded steel, it was like peeling a ripe banana. With the right lathe I could remove .5" from the diameter in one pass. Heat treat this alloy..... NO WAY! It would not respond in the way you wanted it to. You could case harden it but you had to add the carbon to the exterior.

We're dinosaurs.

Kids today, do it by pushing buttons.

I was lucky enough to take an extended machinist's course when I was in an aerospace company.

We did some wild stuff back then.

I never did anything very exotic, but my buddy used to build tiny 24 exposure, one use cameras, that he machined himself (in a private, secure machine shop) and put inside Bic lighters. I never saw a finished lighter (need to know) but he showed me (much later) some very small brass parts with reverse, inside threads that were truly works of mechanical art.

Yep.... however, I would rather be a dinosaur than a millennial!

When you see #8 In reply to #7 ,it means that I was commenting to Original_Macgyver, and NOT YOU!

Don't ask strangers to help you do your job and then insult them!

I did not ask you to comment nor do I expect you do my job. You are a "GURU" and expect you to give an "answer"

I gave you an "answer." It was "Yes."

Being a "GURU" only means that we have encountered any number (over 500) of sometimes very good and sometimes poorly worded questions and answered some, not all, of them depending on many circumstances, including the attitude of the requester.

It's a slow day here in the desert and I am feeling a bit generous. I'll look into your problem tomorrow and get right back to you, as soon as I have found a suitable answer for your question.

I don't need sermons from you. Have you read the question properly?

You want help from some of the best engineers I know of and then you insult them.

Please close the door on your way out.

Sorry for any misunderstanding.

NO, I was not calling you dumb. My posting was an exchange between myself and another long time poster and we converse with each other.

Govind,

The engineers on this site are quite intelligent and very helpful, but, when someone posts a vague generalized question, be prepared for a bit of rough reply.

when you ask a question, have all the facts available and in your post.

I.E.:

  • Specific material?
  • Dimensions?
  • Voltages?
  • Machinery name/brand and capacities?
  • What you are trying to accomplish?
  • What have you tried before your posting of the question?
  • Pictures are always helpful unless too small or blurry
  • Diagrams?
  • Any other information you think we may need to assist you in answering your question!

Have a good day,

Bryan

..."Generally, carbon is the most important commercial steel alloy. Increasing carbon content increases hardness and strength and improves hardenability. But carbon also increases brittleness and reduces weldability because of its tendency to form martensite.Aug 28, 2003"...

Thank You, as I understand, the forging and rolling temperature of carbon steel varies according to the carbon content. That is, higher the carbon content, lower is the the forging temperatures and vice versa.

The understanding answers the original question.

Thanks a lot !!!. If you closely follow the page on #5, you would notice that,more the carbon less is the forging temperature and vice versa. This was what I was looking out for.
