materials from foundry

[isd88]

hello to all, I would like to have some information about foundry materials and techniques in general. I am in front of the difficult task of choosing the material to melt. Taking into account that the stresses imposed by the project constraints are quite high (we are talking about 4-500 mpa si sigma limit) I do not know what kind of material to choose and where to go to look for. for a ground casting the metal alloys are purchased in the form of precise composition crudes or are the alloy elements added before casting? In this case we are talking about a cast steel (imposed by the constraints of the designer). our choice is restricted to materials of particular mechanical characteristics so we thought of a steel tied by carboxing. We did not find any company that provided what we were looking for. Can anyone recommend a company or explain to me how the smelting alloys are prepared?

Hello, I also prepare a similar examination (mechanical technology)... here many give me a hand... From the point of view of the merger I also had the bond of steel... I made a comparison between feg520 and feg780... for my piece I chose the first xkè the encumbrance of my piece is not excessive, the loads are little heavy and besides it is cheaper... If you try to look at the forums find two more of my discussions, maybe take a look at us... can be useful.. .

thank you for the advice! but would you know what company I can ask for these materials? and do they buy with defined composition or go alligate in place?

I think they are already defined, but it would be better to check

Thank you! gs 70 would go well, do you know any company that sells this kind of materials?

Thank you! Now there is another porblema, very different from this and for which I open another tread

How wonderful this forum!
