Custom Stainless Steel Rod | 304L & 317L Alloys Available

Product Specifications

Our stainless steel curtain rods and industrial-grade rods are engineered for durability, corrosion resistance, and precision. Available in 304L (low-carbon) and 317L (high molybdenum) alloys, these rods meet ANSI/AISI and ISO standards for demanding applications.

Key Properties & Manufacturing Process

Our stainless steel filler rod and structural rods are manufactured using vacuum arc remelting (VAR) and precision CNC machining. Post-production heat treatments (quenching, tempering) optimize mechanical properties.

Tensile & Bending Strength

• 304L:
  • Tensile Strength: ≥520 MPa (75,400 psi)
  • Yield Strength: ≥205 MPa (29,700 psi)
  • Bending Strength: Maintains integrity under 210–1,050 MPa stress (annealed to cold-worked states).
• 317L:
  • Tensile Strength: 620–950 MPa (90,000–138,000 psi)
  • Yield Strength: ≥310 MPa (45,000 psi)
  • Bending Strength: Superior stress resistance in acidic environments (e.g., chemical processing).

Identification & Marking

All rods feature traceable identifiers for quality assurance:

• Laser-Etched Codes: AISI/SAE grade (e.g., 304L, 317L) and ISO chemical labels (e.g., X2CrNiMo17-12-2 for 316L).
  
  
• Batch Numbers: Aligned with ASTM A276 (bars) and AWS A5.9 (welding rods).

Weight Calculation

Calculate rod weight using the formula:
Weight (kg)=4000π×(Diameter in mm)2×Length (m)×7.93
Example: A 1/4" (6.35mm) diameter, 3m-long 304L rod weighs 0.75 kg.

Why Does Stainless Steel Rust?

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

1. Chloride Exposure: Saltwater or bleach erodes the chromium oxide layer. Grades like 317L (3% molybdenum) offer enhanced resistance.
2. Low Chromium Content: Grades with <10.5% Cr (e.g., 430) lack passivation. Our 304L/317L alloys contain 18–20% Cr for robust protection.
3. Galvanic Corrosion: Contact with carbon steel or aluminum accelerates oxidation. Use insulating sleeves or compatible alloys.
4. High-Temperature Oxidation: Prolonged exposure above 800°C degrades protective films. 317L excels in high-heat applications.
5. Surface Contamination: Iron particles from tools induce pitting. Regular cleaning with nitric acid passivation restores corrosion resistance.

Applications

• Stainless Steel Curtain Rods: Decorative and structural use in humid environments (e.g., bathrooms, marine interiors).
• Stainless Steel Shower Curtain Rod: Non-rusting, tension-mounted rods (adjustable 37–73") for bathrooms.
• Stainless Steel Filler Rod: Welding pipelines, chemical tanks, and food-grade equipment (ER308L/316L compatibility).
• Industrial Machinery: Valves, shafts, and hydraulic systems requiring high fatigue resistance.
