Precision-Cut Stainless Steel Rod | ANSI/AISI Certified

Precision-Cut Stainless Steel Rod | ANSI/AISI Certified

Product Specifications

Our stainless steel tig rod and welding rod for stainless steel are precision-engineered to meet ANSI/AISI standards, ensuring exceptional performance in industrial, marine, and construction applications. Below are the detailed specifications:

Key Properties & Manufacturing Process

Crafted using advanced CNC machining and controlled heat treatments (quenching, tempering, and precipitation hardening), our stainless steel rods deliver unmatched mechanical properties. Key attributes include:

• Tensile Strength:
  • 304/316: 515–860 MPa (ideal for structural and marine applications).
  • 309: 620–860 MPa (optimized for high-temperature welding).
  • 410: 480–1,720 MPa (heat-treated for extreme durability).
• Bending Strength: Resists deformation under load, with yield strengths ranging from 210 MPa (annealed 304) to 1,050 MPa (cold-worked 316).

Identification & Marking

Each stainless steel rod is traceable to its production batch and compliant with global standards:

• AISI/SAE Codes: Laser-etched grade labels (e.g., 316L, 309L).
• ISO Standards: Chemical composition markings (e.g., X2CrNiMo17-12-2 for 316L).
• Batch Numbers: Aligned with ASTM A276 (bars) and AWS A5.9 (welding rods).

Weight Calculation

Calculate the weight of a 1/4 stainless steel rod or other sizes using the formula:
Weight (kg)=4000π×(Diameter in mm)2×Length (m)×7.93
Example: A 1/4" (6.35mm) diameter, 3m-long 316 rod weighs approximately 0.75 kg.

Why Does Stainless Steel Rust?

While stainless steel is corrosion-resistant, certain conditions can compromise its integrity:

1. Chloride Exposure: Saltwater, bleach, or industrial chemicals degrade the chromium oxide layer.
2. Low Chromium Content: Grades with <10.5% chromium (e.g., 410) lack sufficient passivation.
3. Galvanic Corrosion: Contact with carbon steel or aluminum accelerates oxidation.
4. High-Temperature Oxidation: Prolonged exposure above 800°C causes scaling and embrittlement.
5. Surface Contamination: Iron particles from tools or grinding induce localized pitting.

To mitigate rust, use nitric acid passivation or electropolishing to restore the protective oxide layer.

Applications

• Stainless Steel Tig Rod: Ideal for TIG welding in aerospace, food processing, and chemical industries.
