Import Tips

• PM grades need detailed process/material certs; standard D2/M2 certs insufficient for CPM variants

• Minimum dimension tolerance ±0.1mm required for .10.60; oversized tolerance risks 7228.50.30

• No secondary operations like centerless grinding if resembling hot-rolled; strict cold-finish proof
