Difference Between Sulfur and Silicone in A184M Steel

It sounds as though the steel is wrong, hence the <...trouble progressive stamping...>.

Use the right steel instead.

Sulfer Sulfur _or Sulphur.

Silicone Silicon.

Sorry,

This shows how much I know about this.

It's Sulfur and Silicon.

Thank you,

Sulphur and Silcon are not exclusive as being part of the mix.

Usually there is a lab report with a batch of steel which shows the content of all elements. Then there should be a material specification that tells the limits of the major elements in the mix.

I have nothing about A184M so you would have to find the specification to be sure.

Properties will change with different concentrations of each element. Try this

Thank you.

ASTM A184 / A184M is titled 'Standard Specification for Welded Deformed Steel Bar Mats for Concrete Reinforcement'. This doesn't sound like a specification that would be used in progressive stamping.

I'm just taking the number off of our spec sheet (184M). There is a lot I don't know, if that isn't too obvious. I do know it's a nickel plated cold rolled steel.

It won't be re-bar, then. Rust is important in re-bar to aid the grip with the concrete.

I don't know of any benefit of any appreciable amount of sulfur in steel.

Silicon on the other hand increases electrical resistivity in steel. You stamping what will be electrical parts?

Yes,

But our spec requires Sulfur and the spec sheet of the material states Silicon instead.

Then it's still the wrong steel.

Are you certain that there isn't a requirement to restrict sulfur content to a certain maximum value, rather than a requirement for a minimum value?

That certainly is news to me. I have never heard of sulfur improving the workability of steel. Do you have a reference with more details?

I read in wikipedia that metals with sulfur are more malleable than with metals that don't have any. Our issue here are our parts cracking which says to me that it is more brittle.

Sulfur is known to reduce ductility, impact toughness, and weldability, among other undesirable effect.

Please provide a link to what you read, even Wikipedia as it should have supporting references or be corrected.

I'll have to revise my statement about "workability", the correct word should have been "machineability."

Machinability or workability a reference would still be great and much appreciated.

.

Iron/sulfur compounds should not improve machinability or workability in any way I can think of. If you have some reference to some compound or process which I am overlooking or of which of unaware I would appreciate being made aware (in the form of a reference which I can research further).

There are literally thousands of references available; here are a few:
