Key Features
- Corrosion Resistance: 304L and 316L grades excel in acidic and chloride-rich environments, while 17-4ph offers enhanced resistance to stress corrosion cracking.
- High Strength-to-Weight Ratio: Optimized for structural integrity in load-bearing applications like stainless steel threaded rod systems.
- Machinability: 17-4ph achieves 40–50% machinability, ideal for complex components.
- Weldability: Compatible with stainless steel welding rod (E308L, E316L) for seamless fabrication.
Technical Descriptions
Tensile & Bend Strength
The stainless steel rod delivers superior tensile strength due to its alloy composition. For instance, 17-4ph achieves 1,300 MPa ultimate tensile strength, validated through ASTM A564 testing. Bend strength is equally critical: 304L rods withstand 55% elongation before fracture, ensuring ductility under stress. These properties make it suitable for high-pressure hydraulic systems and stainless steel threaded rod applications requiring fatigue resistance.
Weight Calculation Formula
Calculate the weight of a stainless steel rod using:
Example: A 50mm diameter, 6m long 316L rod (density 8.0 g/cm³) weighs ≈ 94.2 kg.
Identification Marking
Each rod is laser-etched with:
- Grade (e.g., 304L, 17-4ph)
- Diameter (e.g., 25mm)
- Heat Number
- Compliance Marks (ASTM/DIN).
Causes of Stainless Steel Rusting
While stainless steel rod is corrosion-resistant, rust may occur due to:
- Chloride Exposure: Saltwater or de-icing agents degrade the chromium oxide layer, causing pitting.
- Mechanical Damage: Scratches from abrasive tools expose the iron substrate to oxidation.
- Low Oxygen Environments: Stagnant water or sludge prevents oxide layer regeneration.
- Galvanic Corrosion: Contact with carbon steel in humid conditions triggers electrochemical reactions.
Regular cleaning with pH-neutral solutions and avoiding chloride-rich environments can mitigate these risks.
Manufacturing Process
- Material Selection: Billets sourced from ISO-certified mills (e.g., AISI 316L with 16–18% Cr, 10–14% Ni, 2–3% Mo).
- Forming: Cold drawing for tight tolerances (±0.05mm) or hot rolling for large diameters.
- Heat Treatment: Solution annealing (1,040°C for 304L) or aging (480°C for 17-4ph) to enhance mechanical properties.
- Surface Finishing: Electro-polishing for Ra ≤ 0.8μm or sandblasting for industrial aesthetics.
- Quality Assurance: 100% ultrasonic testing, chemical analysis, and third-party certifications.
Applications
- Stainless Steel Welding Rod: Fabrication of pipelines, pressure vessels, and marine components.
- Stainless Steel Threaded Rod: Structural fastening in bridges, solar panels, and heavy machinery.
- Medical & Food Industry: Hypoallergenic and FDA-compliant rods for surgical tools and processing equipment.
