I don't know how to do those calculations, I only know the dimensions and the approximate strength (I put it before)

AISI 301 4/4 ¿Yes?

I have seen the drawing of a sheet with the same spring function. The flat steel says that it is the equivalent to 304 but I suppose that it will also have to be treated later so that it can serve as a spring in that flat spring. I definitely think that the 301 4/4 or also called full hard will...

I have verified that the foil is somewhat magnetic (I think the 301 can be magnetic when heat treated) On the other hand, I attach a photo of the sheet. When I hold it in the center and apply a force of about 1kg, it later recovers its shape. Dimensions are 86mm long, 30mm wide and 0.3mm...

I understand that the symbol is valid for both, and also the RSW annotation

I have seen this: RSW (Resistance Spot Welding) that can be put in that place but I don't know if it is necessary, since it already has the symbol.

What's "typ"?

Good afternoon, I want to know the welding symbols and annotations that must be put on a plane that has some bolts welded on it. I have seen it called resistance welding. I attach an image. Thanks

But I see 301 is used too in the manufacture of springs with a hardness of 40 to 50 HRC Hardness 4/4 or 5/4 that will be equivalent to those in that table...

AISI 301 is stainless and I read that it would also work. Certain? This would be better because it is stainless. And as I said before, I think we should ask him to hold on to serve as a spring.

I will make a manufacturing plan and the company's workshop left it to an external company that has laser cutting, etc. That is, the plan must contain all the necessary annotations for its manufacture from the beginning. I have also seen that if you bend the sheet a lot, it does not return to...

Yes, but my question is... Should I indicate hardened C75S on the drawing? Because the C75S steel is supplied without heat treatment I suppose... Yes, the hardness is 40 to 50 HRC I think.

Exactly. It is a simple sheet with 6 holes. My question is whether I should put hardened C75S or simply C75S in the manufacturing drawing (I don't know if the C75S is supplied already hardened or should I say so) I would also like to know if this steel is stainless or should it be coated. The...

I don't know the strap constant. Being a sheet I don't know how it would be calculated. What I know is that I have seen coiled leaf springs that have this steel. But I doubt if the C75S is supplied hardened or if it needs to be tempered to serve as a strip.

I've seen 40-50 HRC in some pages.also say that the original strap seems stainless (same surface appearance)

No, this part is necessary

Dimensions Width 30mm length 86mm thickness 0.3mm Surface hardness is not important, the important thing is that it acts like a spring. The bending force at its longitudinal ends is minimal, it has to be deformed allowing the passage of a notebook transported by a conveyor belt.

What details are necessary? Dimensions? Forces?

The function of this 0.3 mm thick sheet in the machine is that some rollers mounted on it put pressure on a notebook and once it passes, it recovers its shape. I see that it is a more suitable type of steel for this and that it is supplied in sheets. I assume there is another but I don't know.

Thanks, Spain. I don't know if there is a similar steel.
