Alloy 254 SMO Machinability

Back To 254 SMO Machinability

An extremely high work hardening rate joins with a total inadequacy of sulfur make Alloy 254-SMO very tough to machine. Sharp tools, overpowered machine tools, ample lubrication, positive feeds and slow speeds usually offer the best results.
