CNC Machining
Alloy Steel 1215 is a resulphurised free-machining steel. It is often compared with 1018, but its chemistry allows much faster machining with excellent chip control. We supply Alloy Steel 1215 CNC parts across the UK, from single prototypes to production runs.
It holds tight tolerances and produces a bright surface finish, making it a favourite for high-volume precision turned components. As a result it is often specified for precision turned parts, fittings & couplings and bushings & inserts. Its quoted tensile strength of around 540 MPa gives a useful guide when sizing parts.
Parts are CNC turned or milled. Welding is not recommended, and a coating, plating or oil finish should be specified to prevent corrosion. Send us a STEP file and we will quote your Alloy Steel 1215 CNC parts promptly, with UK-wide delivery. Finish options (coating, plating or oil) can be confirmed when you order.

Values shown are typical supplier figures for Alloy Steel 1215 and may vary with stock condition. Please confirm critical properties before production.
1215 (EN1A) contains additions that break chips cleanly, so it cuts fast, holds tight tolerances and leaves a bright finish. It is one of the most efficient steels for turned parts.
Its free-cutting behaviour makes it well suited to small, precise turned parts in larger quantities. Achievable tolerances depend on part size, geometry and features, so mark any critical tolerances on a 2D drawing with your upload and they will be reviewed and confirmed in your quote.
1215 rusts easily, so plating, coating or oil is recommended. It has poor weldability, so it is best for parts that are not welded.
Typical uses include precision turned parts, fittings and couplings, bushings and inserts, and hydraulic components.
Choose 1215 for high-volume turned parts where fast machining and finish matter most. Choose 1018 when the part needs to be welded or case hardened. Brass C360 is an alternative when corrosion resistance is also needed.
The typical lead time shown for 1215 steel is 10 business days from an approved order. Quantity, finishing and any heat treatment can affect this, and your quote confirms the date before you order.
