AISI 1085 High Carbon Steel Balls supplied by SDBALLS — PRODUCT REFERENCE / FINAL SPECIFICATION BY QUOTATION

PRODUCT OVERVIEW

What are aisi 1085 high carbon steel balls?

AISI 1085 balls are through-hardened high-carbon steel spheres designed for higher hardness and wear resistance than low-carbon case-hardened balls.

They are an economical magnetic option for repeated rolling or sliding contact in non-corrosive environments, but they are not a substitute for AISI 52100 in fatigue-critical precision bearings.

KEY PERFORMANCE FEATURES

Performance that purchasing teams can verify.

Through-hardened wear life

High hardness extends service in rolling, sliding and repeated-contact mechanisms.

Cost-performance balance

Provides a practical step up from low-carbon steel without moving to bearing steel.

Multiple precision levels

Commercial through semi-precision grades support hardware and motion requirements.

Surface protection options

Oiling, blackening or plating can be selected around storage and appearance needs.

TYPICAL APPLICATIONS

Specify the work the ball must perform.

Application names are starting points—not approval of universal suitability. Share the real medium, load, speed, pressure, temperature, life target and compliance needs.

Semi-precision bearings

Moderate-duty rolling systems where full bearing-steel fatigue performance is not required.

Furniture & bicycle components

Durable rolling elements for repetitive motion and load.

Slides, casters & conveyors

Wear-resistant balls for high-volume industrial and hardware mechanisms.

Locks & processing equipment

Agitators, locks, polishing and milling mechanisms for compatible environments.

QUALITY & DOCUMENTATION

Build the evidence into the purchase order.

Document requirements should be defined before quotation so the inspection method, sampling level, traceability and external testing can be planned correctly.

Material verification against the agreed steel grade and purchase specification
Diameter, tolerance and precision-grade inspection using calibrated equipment
Hardness and heat-treatment verification when applicable
Surface finish and visual-defect inspection to the agreed acceptance criteria
Roundness / sphericity and lot-consistency inspection for the specified precision level
Batch traceability through heat, lot and controlled production records
Material certificates and inspection reports available when agreed before quotation
RoHS, REACH, PPAP-style records and third-party testing by project agreement

PRODUCT FAQ

Answers for engineering and purchasing teams.

What sizes are available?

The main-site reference range is 1.5–50.8 mm. Other sizes require production confirmation.

What precision grades can be supplied?

Typical grades include G40, G48, G80, G100, G200, G500 and G1000.

How corrosion resistant is this material?

AISI 1085 is not stainless. Use controlled storage, protective oil, plating or another material for wet and corrosive service.

Are these steel balls magnetic?

Yes. AISI 1085 high-carbon steel balls are magnetic.

Can SDBALLS provide material certificates and inspection reports?

Yes. Define the required material certificate, dimensional report, hardness report, compliance record, PPAP-style documentation or third-party test before quotation so the correct inspection plan can be priced.

Do you support samples and small-quantity orders?

Yes. SDBALLS Industry Corp. supports North American buyers with samples, prototype quantities, repair lots and small-batch programs where the requested size, grade and material condition are available.
