- Heat-treatable to 30–55 HRC
CNC Polishing Quality & Inspection
Each 4130 Alloy Steel part is inspected against your drawing, with critical dimensions verified before release. Material certificates and inspection records are available on request.
Applications of CNC Polishing 4130 Alloy Steel
Typical uses for CNC Polishing 4130 Alloy Steel include precision 4130 Alloy Steel components for instrumentation, automotive, medical, energy and general industrial applications.
Machining 4130 Alloy Steel with CNC Polishing
When finishing 4130 Alloy Steel, machinability is good in annealed condition; machined soft then heat-treated to final hardness. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Why 4130 Alloy Steel?
Customers select 4130 Alloy Steel for CNC Polishing because it is high-strength and hardenable. We handle grade verification and any required heat treatment or finishing.
