SAE 1020 Cold Drawn Steel Bar Carbon Steel — Factory Direct Supplier | Huaxia-Steel

SAE 1020 cold drawn steel bar is a low-carbon general-purpose bar used in shafts, pins, studs, couplings, and precision machined components. Compared with hot-rolled bar, cold drawing tightens tolerance, brightens the surface, and improves straightness. Huaxia-Steel supplies SAE 1020 cold drawn bar from Chinese mills in a wide diameter range with ASTM A108 documentation.

Product Overview

Our SAE 1020 cold drawn bar is produced by hot rolling followed by drawing through a die. The result is a smooth, dimensionally accurate bar that feeds easily into multi-spindle lathes and CNC equipment. Bars can be supplied as-drawn, polished, ground, or cut to short lengths.

Available Grades

From the same production lines we also supply:

SAE 1018 – slightly softer, better chip control for high-speed machining
SAE 1045 – higher carbon for higher strength shafts
SAE 12L14 – free-machining with lead addition
C15 / C15E – EN equivalent for low-carbon applications
S20C – JIS equivalent

Manufacturing Standards

ASTM A108 (cold-finished carbon and alloy steel bar)
SAE J403 (chemical composition)
EN 10277 (delivery conditions for bright bars when requested)
ASTM A29 (general requirements for hot-rolled feedstock)

Applications

CNC turned shafts, pins, and fasteners
Couplings, spacers, and bushings
Light-duty axles and rollers
Hydraulic and pneumatic cylinder components
General-purpose machined fittings

Quality Assurance

Each heat is tested for chemistry, tensile strength, hardness, and dimensional accuracy. Surface roughness is typically Ra 1.0-3.0 microns for polished bars. Mill test certificates to EN 10204 3.1 are supplied with every shipment; third-party inspection by SGS or BV can be arranged on request.

Packing and Shipping

SAE 1020 cold drawn bars are bundled in hexagonal packs with steel straps and wrapped in oiled paper or plastic film for transit rust prevention. We can pack in 20-foot containers for overseas shipments or arrange just-in-time truck delivery for nearby destinations.
