what cast iron per wheel?

[biz]

what type of cast iron to use for wheels of a cart running on heb, considering that:
_ hertzian pressure is very low;
_wear has been evaluated important, data: the race almost continues for 16 hours per day at still contained speed (by wagon); shocks that receive the wheel from rail to rail; the dirty environment (they are not protected rails but are clearly exposed to the normal dust of a warehouse that does not move objects that release particulate or particles in the air).
available for other data.

why not in tempered steel surface induction?

sincerely I would also do them in c45 with surface tempering induction 54/56hrc for a depth of about 3mm as I usually do. if you want something more lasting you can take the prebonified 42crmo4 so that it is more tenacious to heart and then make a superficial tempering as indicated above.
if you keep cast iron wheels means you admit wear wheels and are willing to change them frequently.
Surely you need the spheroidal grige cast irons if you want to make wheels even if those lamellars could lend themselves, with the limits of the slats that break the alloy.

I thought about spherical cast iron too. . .

customer specifications

Can the client reason? Can we explain the advantage of steel?
Does the customer want the wear of the wheel to be unreliable? technical reasons....what?

There's a speech from this point of view. at the end of the fair the customer necessarily wants it in cast iron.

I also believe that cast iron is not the appropriate material... anyway in the case of species I would adopt the versatile g25

If the client puts this conditio, is it not that it depends on the fact that it needs some replicas? also you might want to download them to reduce weight, etc... In this case, with a foundry model, it can be achieved by melting in sand. processing would only affect the hub and rolling track. with spheroidal cast irons appropriately treated thermally, resistors and hardness even greater than those of a tempered c45 (with a gs 800 you get remarkable performance). I wouldn't doubt using the spheroidal cast iron. you just need to have a trust foundry, which can direct you to the best choice.

I would opt for gjs600. In my sector, this material is used for shock and wear-based components (threat knives that process waste material of various kinds) or for others where carbon-like behaviour is required. has already of itself characteristics of tenacity and hardness of much greater than the most fragile lamellars but I am writing obvious things. the cost per kg is higher, the processing is worse.

no, in the past with this solution had sparkles with steel on steel. intolerable for the type of environment in which you work.
