Cold-drawn Carbon Steel Bars - Precision Tolerances, ASTM A108 Certified

Technical Specifications of Cold-Drawn Carbon Steel Bars

Cold-drawn Carbon Steel Bars - Precision Tolerances, ASTM A108 Certified

Cold-drawn carbon steel bars represent a premium grade of carbon steel products manufactured through a specialized cold-drawing process that enhances dimensional accuracy and surface finish. These precision-engineered bars serve critical roles in automotive, machinery manufacturing, and fastener production where tight tolerances and superior mechanical properties are essential. Designed for manufacturers requiring cost-effective materials with exceptional machinability and consistent quality, cold-drawn carbon steel bars deliver reliable performance across demanding industrial applications.

What is Cold-drawn Carbon Steel Bars?

Cold-drawn carbon steel bars are carbon steel products processed at room temperature through drawing dies to achieve precise dimensions, improved surface quality, and enhanced mechanical properties compared to hot-rolled alternatives. This cold-working process increases tensile strength by 15-20% while maintaining excellent machinability for precision component fabrication.

Cold-drawn Carbon Steel Bars Technical Specifications

Our cold-drawn carbon steel bars comply with ASTM A108-18 standards for carbon and alloy steel bars subject to mechanical property requirements. Available in grades 1018, 1045, and 12L14, these bars feature carbon content ranging from 0.15% to 0.50%, with diameter tolerances held to ±0.005 inches per ASTM specifications. Tensile strength ranges from 440 MPa minimum for 1018 grade to 625 MPa for 1045 grade, with surface finish achieving Ra values of 1.6 μm or better through precision drawing operations.

Why Choose Our Cold-drawn Carbon Steel Bars

We maintain mill-direct pricing relationships with ISO 9001:2015 certified manufacturers, ensuring factory-competitive pricing without compromising quality standards. Each production lot undergoes dimensional verification using calibrated micrometers and hardness testing per ASTM E18 protocols. Our extensive inventory includes round bars from 6mm to 150mm diameter and hexagonal bars from 8mm to 50mm across flats, all traceable to certified mill test reports documenting chemical composition and mechanical properties.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Our standard MOQ is 5 metric tons per specification, though we accommodate smaller quantities for premium grades or custom sizes with adjusted pricing. Mixed-specification orders totaling 5 tons qualify for standard rates when shipped to a single destination.

Do you provide material test certificates?

Yes, every shipment includes EN 10204 Type 3.1 mill test certificates documenting chemical analysis per ASTM E415 optical emission spectrometry and mechanical testing results including tensile strength, yield strength, and elongation percentages. Third-party inspection arrangements through SGS or Bureau Veritas are available upon request.

What is the typical delivery time?

Standard specifications from our warehouse inventory ship within 5-7 business days. Custom diameter requirements or special length cutting typically require 3-4 weeks from order confirmation, depending on mill production schedules and current demand for specific grades.

Can you cut to custom sizes?

Our precision sawing capabilities accommodate custom length cutting with tolerances of ±1.0mm for lengths up to 6 meters. We also provide centerless grinding services for diameter refinement to tolerances of ±0.002 inches when applications demand enhanced precision beyond standard cold-drawn specifications.
