ARC-4HG (FC-0208) Remill

ARC-4 HG remill is an iron based mix meeting MPIF FC-0208 chemistry requirements and produced mainly from recycled green powder metal compacts. ARC-4 HG is a press ready mix containing 0.75% lubricant and has somewhat higher green strength than ARC-4. It is commonly used to produce net-shape lawn and garden, light industrial and household goods. ARC-4 HG may be machined, but some applications may not machine as well as new powder mixes. Additions of MnS are common for applications requiring machining.
