SS 17- 4PH Machinability

Back To Stainless Steel Machinability

Long and gummy chips describe SS 17-PH Alloys machinability. It can be machined in the annealed condition, so the condition H1150M will yield best results. Post machining solution treatment of parts will be needed prior to final hardening if machining in this condition.
