1215 and 12L14 Cold Drawn Round Bar Images
Evidence boundary: these images show Junxiong round-bar form and packing capability. Final grade identity and batch conformity are established by the approved purchase specification and order documents, not by appearance alone.
Technical Facts Buyers Must Confirm
| Decision | 1215 enquiry | 12L14 enquiry |
|---|---|---|
| Grade route | Non-leaded free-machining grade designation; confirm the governing standard and restricted-substance limits. | Leaded free-machining grade designation; confirm that lead is permitted for the part, customer specification and destination market. |
| Machining use | CNC turned parts, Swiss-type machining, automatic-lathe parts, pins, bushings, fittings, spacers and precision hardware. | |
| Bar data | Diameter, tolerance class, straightness, surface condition, end condition and random or fixed length. | |
| Order control | Heat identification, MTC, inspection method, packing, quantity per size and delivery schedule. | |
Trade names used in different countries are useful for search and comparison, but similar names are not proof of equivalence. Junxiong reviews the requested chemistry, mechanical properties, dimensional requirements and certificate wording before confirming a grade.
Common International Search Names

Standards and Primary Reference Sources
- SAE J403_202402: the SAE source for carbon-steel chemical-composition designations. Use the edition required by the purchase contract.
- ASTM A108-24: the active ASTM specification for carbon and alloy cold-finished steel bars, including purchaser-specified supplementary requirements.
- BS EN 10277:2018: technical delivery conditions for bright steel products, including free-cutting steel routes.
- JIS G 4804:2021: the Japanese standard for free-cutting steels used when a buyer specifies a SUM grade route.
Reference boundary: these publisher sources identify possible procurement routes; they are not Junxiong heat certificates and do not prove that 1215, 12L14, 11SMn30, 11SMnPb30, 1.0715, 1.0718, SUM23 or SUM24L are automatically interchangeable. The approved standard, exact grade, product form, dimensions, restricted-substance limits and heat-specific MTC control the order.
For a controlled comparison of the SAE, EN and JIS search families, use the 1215 vs 12L14 grade-selection guide.
Round Bar Specification and Process Review
- Section: round bar only for the primary offer on this page.
- Size: state finished diameter and tolerance class; the published general cold-drawn round-bar capability is indicative and every grade-size combination requires review.
- Straightness: state the measuring method, span and maximum permitted deviation.
- Surface: specify cold drawn, bright, peeled, ground or another approved condition.
- Length: state random or fixed length, length tolerance and end condition.
- Processing: straightening, cut-to-length and export packing can be reviewed by order.
- Inspection: define MTC, heat traceability, chemistry, mechanical-property or third-party inspection requirements before production.
For bar-fed CNC and Swiss-type machines, include the bar feeder, finished component, machining route and repeat-demand estimate. This lets engineering review straightness, surface and length as production inputs rather than treating diameter alone as sufficient.
Factory and Order-Document Verification
Junxiong Metal is the export brand for cold drawn steel products manufactured by Wuxi Dishang Profile Steel Technology Co., Ltd. Buyers can review the current company identity, ISO 9001 certificate, factory evidence and quality-control information on the Factory and Quality Verification page.
Certificates and representative images establish company capability. They do not replace the MTC, heat number, approved specification or inspection results for the buyer’s actual 1215 or 12L14 order. State every required document in the purchase enquiry so it can be included in the production review.
What the Available 1215 Records Can Prove
Junxiong’s private historical source file includes five steel-mill certificates for 1215 or SAE 1215 hot-rolled round feedstock in nominal diameters of 50, 65, 90, 95 and 110 mm. Depending on the certificate, the recorded checks include chemistry, mechanical properties, hardness, macrostructure or surface inspection. These records support upstream material review; they are not certificates for a later finished cold-drawn-bar batch.
| Evidence level | What it can support | What it cannot establish alone |
|---|---|---|
| Upstream steel-mill certificate | Mill-issued grade, standard, heat or lot, feedstock size and the test values printed on that certificate. | Finished cold-drawn diameter, tolerance, straightness, surface, length or conformity of a different heat or order. |
| Internal trace record plus finished-bundle label | A link between one identified finished batch and its upstream heat when the identifiers and production record match. | Dimensional or surface conformity unless the corresponding finished-batch inspection results are also supplied. |
| Finished-batch inspection pack | Agreed diameter, tolerance, straightness, surface, length and other checks for the identified delivery batch. | Any other grade, heat, diameter or future order. |
Current release boundary: raw source certificates remain private and are not presented here as Junxiong finished-product certificates. A buyer may request controlled document review for a quoted order. Where disclosure is permitted, customer and order identities are redacted, while the grade, standard, heat or lot, test results, date and issuer remain unchanged.
RFQ instruction: write “1215 document pack required” in the enquiry and state the finished diameter, tolerance, straightness method, length, quantity and destination. Junxiong will confirm which upstream and finished-batch records can be contractually supplied before production.

Need 1215 or 12L14 in a Non-Round Shape?
This page intentionally keeps its primary offer and images limited to round bar. Buyers who need free-cutting steel in hexagonal, square or flat sections should use the free-cutting steel bar shape-selection and RFQ guide. It separates across-flats, side-size and width-by-thickness requirements so a non-round enquiry is not priced as round stock.

FAQ for 1215 and 12L14 Round Bar Buyers
Can Junxiong quote both 1215 and 12L14 cold drawn round bars?
Yes. Send the governing standard, diameter, tolerance, straightness, length, quantity and destination. Final supply is confirmed only after grade and production feasibility review.
Is 12L14 automatically interchangeable with 11SMnPb30 or SUM24L?
No. These names are often compared by buyers, but the approved standard, chemistry, mechanical properties and certificate requirements must be checked before substitution.
Is 1215 a lead-free material?
1215 is commonly specified as a non-leaded free-machining grade, but “lead-free” can imply a separate regulatory limit. State the required standard and restricted-substance threshold so the order can be reviewed correctly.
What information is important for Swiss-type or automatic-lathe use?
Confirm diameter tolerance, straightness, surface condition, fixed length, end condition, bar-feeder requirements, finished component and expected repeat quantity.
Can Junxiong provide an MTC and heat-number traceability?
MTC and heat-traceability requirements can be reviewed by order. They must be stated before production so the agreed documentation follows the delivered batch.
Can other bar shapes be supplied?
Hexagonal, square, flat and custom sections can be reviewed separately. Use the dedicated shape page or provide a section drawing so the quotation does not mix round-bar and non-round requirements.
