SAE/AISI 1020 Cold Drawn Carbon Steel Bars
Short Answer for 1020 Cold Drawn Steel Bar Buyers
Junxiong Metal can review SAE/AISI 1020 cold drawn carbon steel bar enquiries in round, square, flat, hexagonal and drawing-based sections. A complete RFQ requires the governing standard, shape, finished size, tolerances, surface, delivery condition, required properties, length, quantity, destination and MTC requirements.
1020, C22 and S20C are sometimes searched or compared across markets, but this page does not declare them automatically interchangeable. The buyer-approved standard, chemistry, mechanical-property requirements and delivery condition control the order.

Representative Cold Drawn Round Bar Images
Image boundary: steel grade cannot be verified from appearance. These Junxiong images show a relevant cold-drawn round-bar form only and are not presented as SAE/AISI 1020 batch evidence.
Supply Scope and Evidence Boundary
Junxiong has confirmed commercial supply capability for SAE/AISI 1020 requirements. Current stock, every product shape and every international comparison designation are not implied. Grade-specific photos and order or batch evidence remain release gates for paid traffic.
Evidence boundary: a supply statement or quotation is not a shipment record, current-stock declaration, heat certificate or dimensional inspection report. Each order is confirmed against the approved specification, production route and order or batch documents.
Technical Facts Buyers Must Confirm
| Decision | Required RFQ information |
|---|---|
| Grade route | SAE/AISI 1020 or another buyer-approved carbon-steel standard and edition; comparison designations require a separate standard-by-standard review. |
| Delivery condition | State as-drawn, annealed, normalized or another explicitly approved condition, plus required properties where applicable. |
| Product form | Round, square, flat, hexagonal or a drawing-based section, with the intended machining or forming route. |
| Dimensions | Finished size, tolerance, corner radius where applicable, straightness, twist and length tolerance. |
| Inspection | Heat identity, MTC type, chemistry, mechanical properties, hardness, decarburization or additional inspection requirements. |
| Commercial data | Quantity per size, repeat demand, packing, destination country, port and required delivery schedule. |
Shape and RFQ Selection
| Shape | Buyer must state | Factory review |
|---|---|---|
| Round bar | Diameter, tolerance, straightness, surface, length and bar-feeder or machining requirements. | Starting material, process route, tooling, inspection, MOQ and schedule are reviewed for the exact grade-size-condition combination. |
| Square bar | Side size, tolerance, corner radius, twist, straightness and length. | Starting material, process route, tooling, inspection, MOQ and schedule are reviewed for the exact grade-size-condition combination. |
| Flat bar | Width, thickness, edge condition, flatness, straightness and length. | Starting material, process route, tooling, inspection, MOQ and schedule are reviewed for the exact grade-size-condition combination. |
| Hexagonal bar | Across-flats size, tolerance, twist, straightness and length. | Starting material, process route, tooling, inspection, MOQ and schedule are reviewed for the exact grade-size-condition combination. |
| Custom profile | Dimensioned drawing, critical tolerances, corner radii, datum scheme, annual demand and trial quantity. | Starting material, process route, tooling, inspection, MOQ and schedule are reviewed for the exact grade-size-condition combination. |
Standards and Primary Reference Sources
- SAE J403_202402: SAE publisher route for chemical compositions of SAE carbon steels; the order must state the required edition.
- ASTM A108-24: ASTM specification route for carbon and alloy cold-finished steel bars.
- BS EN 10277:2018: Technical delivery conditions for bright steel products; it does not by itself make C22 identical to SAE/AISI 1020.
Reference boundary: publisher, association and mill pages support terminology and buyer verification. They are not Junxiong heat certificates and do not prove that every designation, product form or delivery condition is interchangeable.
Buyer Checklist Before Quotation
- Exact grade designation, governing standard and standard edition.
- Shape, finished dimensions and machining allowance.
- Dimensional tolerance, straightness, twist and corner-radius limits.
- Delivery and heat-treatment condition.
- Surface condition and defect limits.
- Required mechanical properties, forming or machining route and any decarburization limit.
- MTC, heat traceability and third-party inspection requirements.
- Quantity per size, repeat demand, destination, schedule and packing.
FAQ for 1020 Cold Drawn Steel Bar Buyers
Can Junxiong supply 1020 cold drawn round bar?
Junxiong can review the requirement after receiving the governing standard, diameter, tolerance, straightness, surface, condition, quantity and destination.
Is C22 or S20C exactly the same as SAE/AISI 1020?
No automatic substitution is assumed. These are useful comparison terms, but chemistry, properties, delivery condition and the governing standard must be checked before quotation.
Can 1020 square, flat and hexagonal bars be reviewed?
Yes, subject to exact dimensions, tolerances, tooling, reduction route, condition and order quantity.
What buyer information prevents an inaccurate quote?
State the governing standard and edition, shape, finished size, tolerance, condition, properties, length, quantity, packing and destination.
Can an order include MTC and heat traceability?
Yes, when certificate type, heat traceability and required chemistry, mechanical or supplementary test items are agreed before production.
