FREE-MACHINING CARBON STEEL · DEFINE YOUR PART
1215 Carbon Steel for Your Precision Turned Parts
Review machining, joining and final fit together.
For your 1215 steel machining inquiry, specify the material condition, thread engagement, bore fits, burr access and finish. Agree restrictions before choosing this free-machining grade.

Choose 1215 from Your Finished-Part Requirement
1215 is resulfurized and rephosphorized free-machining carbon steel. It is associated with screw-machine stock and turned components such as fittings, couplings, pins and bushings.
For custom 1215 steel parts, connect the material selection with your service conditions and any joining or forming requirement. Machinability alone does not approve the application.

European comparison
11SMn30 / 1.0715, historically 9SMn28, appears as a parenthesized comparison in the cited 1215 producer sheet.
Review before substitution
Chemistry limits differ. Approve the full product standard, condition, required properties and material restrictions before accepting an alternative.
Plan Your Turned Features and Secondary Operations
1215 Steel Turning
Identify bore-to-diameter relationships, shoulder positions and useful thread engagement. Include allowed gripping areas.
CNC Turning →
1215 Steel Milling
Show wrench flats, slots and cross-holes relative to the turned datum. Agree secondary setups and burr-removal access.
CNC Milling →3 Drawing Checks for Your Finished Fit
01 · YOUR DRAWING CHECK
Give the functional engagement and gauge access.
For your 1215 steel threaded parts, specify thread standard, useful depth, shoulder clearance and final fit after any surface protection.
DFM & Drawing Review →
02 · YOUR DRAWING CHECK
Make the internal edge requirement inspectable.
For 1215 steel drilling, tapping and deburring, identify intersecting passages, allowed edge breaks and access for cleaning and verification.
DFM & Drawing Review →
03 · YOUR DRAWING CHECK
Define the finish system and masked surfaces.
For 1215 steel black oxide or 1215 steel zinc plating, state exposure, coating specification, thickness where relevant and protected threads or bores. Review suitability for your actual service conditions.
DFM & Drawing Review →Resolve Joining, Forming & Treatment Before Ordering
Joining
Do not select a free-machining sulfur-rich grade for a weldment without engineering review. State the joint and service requirement first.
Forming or thread rolling
A cut thread and a rolled thread impose different process demands. Identify the intended route for project-specific material and process review.
Heat treatment
The cited 1215 producer sheet classifies it as not intended for heat treatment. If your drawing requires hardness or treatment, review the grade choice and acceptance route before ordering.
Keep Your Material and Part Records Together
For your 1215 steel machined parts, agree what your receiving team needs to accept the order.
- Grade, product standard, stock condition and lot identity.
- Critical fits, thread gauging and burr inspection.
- Surface protection and final dimensional state.
- Material declarations and inspection documents when required.
1215, 12L14 or 1018: Compare Your Constraints
| Decision | Your comparison input |
|---|---|
| 1215 vs 12L14 steel | Review lead restrictions, actual chemistry, required properties and joining. Do not assume zero lead from an incomplete chemistry table. |
| 1215 vs 1018 steel | Compare free-machining chemistry, joining or forming needs, stock condition and final acceptance. |
| 1215 steel properties | Request evidence for the actual product form, section and supplied condition rather than applying one generic strength. |

Answers Before You Choose
Does 1215 steel contain lead?
1215 is not the leaded 12L14 grade. The cited 1215 chemistry table does not specify a lead range; it also does not certify zero lead. State any lead-content limit and request appropriate material evidence.
Can 1215 steel be welded?
Review joining before selecting this sulfur-rich free-machining grade. The actual joint, section, service conditions and qualified process need assessment.
Does 1215 steel rust?
It is carbon steel. Define exposure, storage and the protective finish your component requires.
What is 1215 steel used for?
Turned fittings, couplings, pins, bushings and studs are producer examples. Select it against your actual material restrictions and finished-part requirements.
How much does 1215 steel machining cost?
For your 1215 steel machining quote, send CAD, drawing, supplied condition, quantity, secondary operations, finish and inspection scope.
Can 11SMn30 replace 1215?
Treat it as a comparison candidate. The selected chemistry ranges differ; approve the product standard, condition and required performance before substitution.
