Chaplet posts for GI Grade 25

[mechvhstech]

Hello All,

We use Grade 8 bolts to support chaplets in the green sand mold. We are also experiencing uneven wear on these chaplets owing to pouring temps. Does anyone have any insight to whether changing the matl. to ceramic or tool steel improve performance?

Thanks.

Please come with more details. The chaplets are to fuse with the liquid metal. Does this not happen? It seems you are reusing the chaplets to observe wear. also what is the wear due to?
