Pure Iron Rod without Hairline

 Product Overview

Pure Iron Rod without Hairline is a premium-grade iron product engineered to meet the stringent demands of industries requiring flawless surface quality and structural integrity. Manufactured through specialized processes that eliminate surface imperfections like hairlines, these rods deliver exceptional smoothness, uniformity, and reliability for precision components in critical applications.

Composition

Base Material: Iron (Fe) ≥99.5% (custom grades up to 99.8% available).

Carbon (C): ≤0.03% (for balanced magnetic and mechanical properties).

Silicon (Si), Manganese (Mn), Sulfur (S), Phosphorus (P): <0.15% total.

Manufacturing Process & Features

1. Cold Rolling & Drawing

High-purity iron billets are processed through precision cold rolling and drawing to refine grain structure, reducing internal stresses that cause surface defects.

2.Surface Inspection

Advanced non-destructive testing (NDT) identifies and removes rods with micro-cracks or hairlines during production.

3.Electropolishing or Mechanical Polishing

Achieves a smooth, mirror-like finish (e.g., Ra ≤ 0.8 μm) free from hairlines, scratches, or oxidation.

Acid Cleaning: Removes residual oxides and contaminants to ensure pristine surfaces.

4.Precision Cutting

Customizable diameters (5–80 mm) and lengths (1–6 meters) with tolerances as tight as ±0.03 mm.

Key Advantages

Technical Specifications

Package

Pure iron is typically packaged with rust-preventive oil, wrapped in plastic film, and secured with plastic or metal straps. It is then placed on wooden pallets or in wooden crates, sometimes using moisture-proof paper or vacuum packaging for extra protection during transportation and storage.
