When it comes to selecting wire rope for applications requiring both strength and flexibility, the 3/16 7x19 stainless steel cable stands out as a popular and reliable choice. This article explores the strength characteristics, construction, applications, and maintenance of this cable, providing a comprehensive guide for engineers, riggers, architects, and DIY enthusiasts. We will also include helpful visuals and videos to enhance understanding.
- 3/16 refers to the cable diameter, which is 3/16 of an inch (approximately 4.76 mm).
- 7x19 describes the cable's construction: it consists of 7 strands, each made up of 19 individual wires, totaling 133 wires twisted together. This configuration offers an excellent balance between flexibility and strength.
The cable is typically made from Type 304 or Type 316 stainless steel. Type 304 is widely used for its corrosion resistance and strength, while Type 316 includes molybdenum, enhancing corrosion resistance especially in marine environments.
The breaking strength of the 3/16 7x19 stainless steel cable varies slightly depending on the stainless steel grade:
| Stainless Steel Type | Breaking Strength (lbs) | Working Load Limit (lbs) | Notes |
|---|---|---|---|
| Type 304 | ~3,700 lbs | ~740 lbs | Common general-purpose cable |
| Type 316 | ~2,900 - 3,565 lbs | ~713 lbs | Marine-grade, superior corrosion resistance |
The working load limit (WLL) is typically calculated using a safety factor of 5:1, meaning the cable should never be loaded beyond about 740 lbs for Type 304 or 713 lbs for Type 316 to ensure safety and longevity.
Type 316 stainless steel, while more corrosion-resistant due to molybdenum content, contains less carbon, which slightly reduces its tensile strength compared to Type 304. However, it is preferred for harsh marine environments.
The 7x19 construction is highly flexible, making the cable suitable for applications requiring bending around pulleys or winches without fatigue. Compared to 7x7 construction, 7x19 cables have:
- Greater flexibility
- Better fatigue resistance
- Slightly lower abrasion resistance
- Slightly lower breaking strength (but still very strong)
This makes 3/16 7x19 stainless steel cable ideal for dynamic applications where movement and bending are frequent.
- Rigging and standing rigging on sailboats
- Winch lines and pulleys
- Dock and marina barriers
- Anchor and mooring lines
The cable's corrosion resistance and flexibility make it ideal for saltwater exposure.
- Cable railing systems for decks, stairs, and balconies
- Structural bracing and support in buildings
- Suspension bridges and tension structures
Its sleek appearance combined with strength provides both safety and aesthetic appeal.
- Hoisting and lifting applications (consult rigging professionals)
- Exercise equipment cables
- Security cables and tie-downs
- Pulley and control cable systems
- Garden fences and trellises
- Clotheslines
- Decorative cable installations
- Regularly clean cables with fresh water to remove salt and debris.
- Inspect for broken wires, corrosion, or wear before each use.
- Apply rust-preventative coatings if necessary.
- Avoid shock loads or loading near breaking strength.
- Replace cables showing signs of fatigue or damage immediately.
- Always use cables within their working load limits.
- Use appropriate end fittings and hardware compatible with stainless steel.
- Employ a safety factor of at least 5:1 for critical or overhead lifting.
- Consult with rigging professionals for overhead or load-bearing applications.
When selecting your cable, consider:
- Material grade: Choose Type 316 for marine or corrosive environments; Type 304 for general use.
- Load requirements: Confirm breaking strength and working load limit meet your needs.
- Flexibility needs: 7x19 construction offers superior flexibility for dynamic applications.
- Length and finish: Order cable by the foot or spool, and ensure compatible fittings.
- Safety certifications: Look for cables meeting ASTM and federal specifications.
The 3/16 7x19 stainless steel cable is a versatile, strong, and flexible wire rope solution widely used in marine, architectural, industrial, and residential applications. With a breaking strength around 3,700 lbs for Type 304 and slightly less for Type 316, it offers a reliable working load limit near 740 lbs, ensuring safety when used properly. Its 7x19 construction provides excellent flexibility and fatigue resistance, making it ideal for applications involving bending and movement. Proper maintenance and adherence to safety guidelines extend the cable's lifespan and performance. Whether for rigging, railing, or securing loads, this cable is a durable and corrosion-resistant choice.
The breaking strength is approximately 3,700 lbs for Type 304 stainless steel and about 2,900 to 3,565 lbs for Type 316 stainless steel, depending on manufacturer specifications.
It means the cable is made of 7 strands, each consisting of 19 individual wires, totaling 133 wires. This construction balances strength with flexibility.
Yes, but only if it meets safety standards and is used within its working load limit. Consult a rigging professional before using it for critical overhead lifting.
Regularly clean with fresh water, inspect for damage, avoid shock loads, and apply rust prevention as needed. Replace if any signs of wear or broken wires appear.
Type 304 is generally stronger in tensile strength, but Type 316 offers superior corrosion resistance, especially in marine environments. Choose based on your application needs.
