What is Metal Treating?
Metal treating (also called heat treatment) is a group of controlled heating and cooling processes used to alter the physical and mechanical properties of metals. These processes can dramatically increase surface hardness, wear resistance, and fatigue life — making treated components last significantly longer under demanding conditions.
RPM Machining Ltd. coordinates metal treating services through our trusted partner network. We offer three primary treating processes: induction hardening for localized surface hardness, carburizing for deep case hardening of low-carbon steels, and gas nitriding for surface hardening without distortion. We manage the entire process so you receive a finished, treated component ready for service.
Our Process
Machining to Specification
Parts are precision-machined at our Yorkton facility, often with allowances built in for any dimensional changes that may occur during heat treatment.
Treatment Selection
We help determine the right treating process for your application — induction hardening for targeted areas, carburizing for deep case depth, or nitriding for distortion-free hardening.
Partner Coordination
We coordinate with our specialized heat treating partners, providing full material and dimensional specifications to ensure the correct process parameters are applied.
Heat Treatment Process
Your parts undergo the specified treatment under controlled conditions. Process parameters are carefully monitored to achieve the required hardness and case depth.
Post-Treatment Inspection
Treated parts are inspected for hardness (Rockwell or equivalent), case depth, and dimensional accuracy to confirm they meet your specifications.
Finish Machining & Delivery
If required, post-treatment finish machining (such as grinding) is performed before final delivery anywhere in Canada.
