SAE 1018 Cold Drawn Aisi 1020 Grade Carbon Steel Round bar
Round Steel (Round Bar) Introduction
Round steel, also commonly referred to as round bar, is a fundamental solid steel product characterized by its circular cross-section. Produced through processes like hot rolling, cold drawing, or forging, it offers exceptional versatility, uniform mechanical properties, and ease of fabrication—making it a cornerstone material in manufacturing, construction, machinery, and precision engineering across the globe.
Key Performance Characteristics
Uniform Mechanical Properties: The circular cross-section ensures even stress transfer, eliminating weak points and enabling reliable performance in both static and dynamic load scenarios.
Dimensional Versatility: Available in an extensive range of diameters—from 5mm (micro round bar for precision instruments) to over 1000mm (heavy forging round bar for industrial machinery)—and lengths up to 12m (or custom-cut).
Superior Machinability: The smooth surface and consistent grain structure (especially in cold-drawn variants) allow for high-precision machining, reducing tool wear and improving production efficiency.
Grade Adaptability: Manufactured from diverse steel types (carbon steel, alloy steel, stainless steel, etc.), enabling customization of properties like strength, corrosion resistance, and heat resistance.
Cost-Effectiveness: As a standardized mass-produced product, hot-rolled round steel avoids the complexity and cost of custom profiles, while cold-drawn variants offer precision without excessive expense.
