What Is a 3/16 Inch Stainless Steel Cable?

3/16 inch stainless steel cable refers to a wire rope with a diameter of 3/16 inches (approximately 4.76 mm), constructed from high-grade stainless steel wires twisted or braided together. The two most common stainless steel grades used are 304 and 316, each offering unique benefits in terms of corrosion resistance and mechanical properties.

Key Features

- Diameter: 3/16 inch (4.76 mm)

- Material: Stainless steel (typically 304 or 316)

- Construction: Most commonly 7x19 or 1x19 strand configurations

- Applications: Marine rigging, cable railings, lifting, winching, industrial use, trellis systems, and more

Types of 3/16 Inch Stainless Steel Cable

7x19 Construction

- Description: Composed of 7 bundles of 19 wires each, twisted together.

- Properties: Highly flexible, suitable for pulleys, winches, and applications requiring bending and movement.

1x19 Construction

- Description: Made from 19 single wires twisted into a single strand.

- Properties: Stiff and smooth, ideal for standing rigging, architectural railings, and applications where minimal stretch and maximum straightness are required.

Breaking Strength of 3/16 Inch Stainless Steel Cable

The breaking strength is the maximum force that the cable can withstand before it fails. This value varies depending on the cable's construction and the grade of stainless steel used.

Typical Breaking Strengths

Construction Material Breaking Strength (lbs)
7x19 304 SS 3,700 – 4,200
7x19 316 SS 3,700 – 4,200
1x19 316 SS 4,000 – 4,270

- 7x19 304 Stainless Steel: ~3,700 lbs

- 7x19 316 Stainless Steel: ~3,700 – 4,200 lbs

- 1x19 316 Stainless Steel: ~4,000 – 4,270 lbs

The breaking strength is not the same as the working load limit (WLL). The WLL is typically calculated by dividing the breaking strength by a safety factor (often 5:1), resulting in a much lower value for safe everyday use.

Working Load Limit (WLL)

The working load limit is the maximum load that should be applied to the cable during regular use. For a 3/16 inch stainless steel cable, the WLL is generally:

- WLL (7x19, 3,700 lbs breaking strength, 5:1 safety factor): 740 lbs

Always adhere to the manufacturer's recommendations and never exceed the WLL for safety.

Mechanical Properties and Performance

Flexibility

- 7x19 Construction: Highly flexible, ideal for applications involving pulleys, winches, or frequent movement.

- 1x19 Construction: Rigid, best for railings and static support where straightness is essential.

Corrosion Resistance

- 304 Stainless Steel: Good corrosion resistance, suitable for most environments.

- 316 Stainless Steel: Superior corrosion resistance, especially in marine or saltwater environments.

Fatigue Resistance

- 7x19: Better fatigue resistance due to more wires and flexibility.

- 1x19: Less fatigue resistance but higher tensile strength.

Common Applications of 3/16 Inch Stainless Steel Cable

Marine and Nautical Uses

- Sailboat rigging

- Dock lines

- Lifelines

Architectural and Residential

- Cable railings for decks and stairs

- Balustrades

- Fencing

Industrial and Agricultural

- Lifting and hoisting

- Winching

- Trellis systems for vineyards and gardens

Safety and Security

- Safety barriers

- Fall protection systems

Installation and Handling

Cutting 3/16 Inch Stainless Steel Cable

A high-quality cable cutter is essential for cleanly cutting stainless steel cable. Watch the following video for a demonstration:

Proper installation ensures safety and longevity. Here's a video guide for installing turnbuckles on 3/16 inch stainless steel cable:

Hand crimping tools can be used for 3/16 inch stainless steel cable, but ensure you use the correct sleeves and follow manufacturer instructions for secure fittings.

Safety Considerations

- Do not exceed the working load limit.

- Inspect cables regularly for fraying, corrosion, or damage.

- Avoid shock loading (sudden force or impact).

- Use proper end fittings and secure all connections.

- Follow all relevant standards and manufacturer guidelines.

Advantages of 3/16 Inch Stainless Steel Cable

- High strength-to-weight ratio

- Excellent corrosion resistance

- Long lifespan with minimal maintenance

- Versatility across many industries

- Aesthetically pleasing for architectural projects

Limitations and Considerations

- Heavier and stiffer than smaller diameter cables (e.g., 1/8 inch), making installation slightly more challenging.

- Higher cost compared to galvanized steel cables.

- Requires specialized tools for cutting and crimping.

Conclusion

The 3/16 inch stainless steel cable is a robust, versatile, and reliable solution for a wide range of applications. With breaking strengths typically between 3,700 and 4,270 lbs, and exceptional resistance to corrosion—especially in type 316 stainless steel—it is well-suited for marine, architectural, industrial, and agricultural uses. Always adhere to the working load limits, use proper installation techniques, and perform regular inspections to ensure safety and longevity. Whether you need flexibility for pulleys or stiffness for railings, the 3/16 inch stainless steel cable offers performance and durability that professionals trust.

Frequently Asked Questions

1. What is the breaking strength of a 3/16 inch stainless steel cable?

The breaking strength varies by construction and material, but most 3/16 inch stainless steel cables have a breaking strength between 3,700 lbs and 4,200 lbs for 7x19 construction, and up to 4,270 lbs for 1x19 construction.

2. What is the working load limit for a 3/16 inch stainless steel cable?

The working load limit (WLL) is typically one-fifth of the breaking strength. For a 3/16 inch cable with a 3,700 lbs breaking strength, the WLL is around 740 lbs.

3. Is 3/16 inch stainless steel cable suitable for outdoor or marine environments?

Yes, especially if you choose type 316 stainless steel, which offers superior corrosion resistance in marine and saltwater environments.

4. What are the main differences between 7x19 and 1x19 constructions?

- 7x19: More flexible, better for dynamic applications (pulleys, winches).

- 1x19: Stiffer, ideal for railings and static supports where straightness is needed.

5. Can I cut and install 3/16 inch stainless steel cable myself?

Yes, with the right tools. Use a heavy-duty cable cutter for clean cuts and appropriate swaging or crimping tools for secure fittings. Video tutorials are available for guidance.
