MAXIMIZE WEAR RESISTANCE WITH SA550NM MANGANESE

SA550NM 11-14% Manganese Wear Plate (500 HB)

SAS Global SA550NM is a high-performance, solution-treated and quenched austenitic manganese steel (11-14% Mn) designed to thrive in the harshest conditions. Engineered for applications where high-impact and gouging abrasion are the norm, this advanced alloy work-hardens up to 550 Brinell (BHN), delivering exceptional resistance to wear in cold working environments.


If your operation demands superior durability in high-impact zones—whether in mining, crushing, or heavy industrial applications—SA550NM is built to outlast and outperform. Let your equipment work harder, longer, and with reduced downtime.


Upgrade to SA550NM and redefine durability in your operation.
