Postalloy 2820-SPL

Characteristics:  A medium alloy chromium carbide overlay for applications involving high impact combined with abrasion. Weld metal is tougher than conventional chromium carbide alloys with fewer stress relieving check-cracks.

Typical Applications Most applications involve high impact and crushing, such as the final overlay on crusher jaws, cone and roll shells, hammer mill hammers, impact breaker bars and pulverizing hammers.
