Ultra-Strong Stainless Steel Rod | Marine & Aerospace Grade

Ultra-Strong Stainless Steel Rod | Marine & Aerospace Grade

Product Specifications

Our 1/2 stainless steel rod is engineered for extreme environments, combining unparalleled strength and corrosion resistance to meet the rigorous demands of marine, aerospace, and industrial applications. Below are the detailed specifications:

Key Properties & Manufacturing Process

Our stainless steel rods are crafted using advanced vacuum arc remelting (VAR) and controlled thermo-mechanical processing to optimize grain structure and eliminate impurities. Key attributes include:

• Tensile Strength:
  • 17-4 PH: 1,100–1,400 MPa (precipitation-hardened for aerospace landing gear and turbine shafts).
  • Custom 465: Up to 1,900 MPa (used in high-stress components like aircraft fasteners).
  • 316L: 515–860 MPa (ideal for marine hardware exposed to saltwater).
• Bending Strength: Resists deformation under load, with yield strengths ranging from 210 MPa (annealed 316L) to 1,800 MPa (cold-worked Custom 465).

Identification & Marking

Each stainless steel rod is laser-etched for traceability and compliance:

• AISI/SAE Codes: Grade-specific labels (e.g., 17-4 PH, 316L).
• ISO Standards: Chemical composition markings (e.g., X5CrNiMo17-12-2 for 316L).
• Batch Numbers: Aligned with ASTM A276 (bars) and AMS 5643 (aerospace standards).

Weight Calculation

Calculate the weight of a 1/2 stainless steel rod using the formula:
Weight (kg)=4000π×(Diameter in mm)2×Length (m)×7.93
Example: A 1/2" (12.7mm) diameter, 6m-long 17-4 PH rod weighs approximately 7.5 kg.

Why Does Stainless Steel Rust?

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

1. Chloride Exposure: Saltwater or industrial chemicals degrade the chromium oxide layer. Grades like 316L (2% Mo) offer enhanced resistance.
2. Low Chromium Content: Grades with <10.5% Cr lose passivation. Our 17-4 PH and 316L alloys contain 15–17% Cr for robust protection.
3. Galvanic Corrosion: Contact with carbon steel or aluminum accelerates oxidation. Use insulating sleeves or compatible alloys.
4. Thermal Stress: Prolonged exposure above 800°C causes scaling. 17-4 PH retains strength up to 600°C post-heat treatment.
5. Surface Contamination: Iron particles from tools induce pitting. Regular cleaning with nitric acid passivation restores corrosion resistance.

Applications

• Stainless Steel TIG Welding Rod: Ideal for aerospace TIG welding, ensuring high-strength, corrosion-resistant joints in fuel systems and exhausts.
• Stainless Steel Shower Rod: Non-rusting, tension-mounted rods (adjustable 37–73") for marine and high-humidity environments.
• Aerospace Components: Landing gear, turbine shafts, and fasteners requiring fatigue resistance and tensile strength >1,800 MPa.
• Marine Hardware: Propeller shafts, hull reinforcements, and offshore rig components resistant to saltwater pitting.
