Understanding SS 310 V Shape Zig Zag Anchors: Design, Benefits & Industrial Applications
In high-temperature industrial settings, the structural stability and efficiency of refractory linings depend heavily on the quality of the anchoring system. One of the most reliable and widely used solutions is the SS 310 V Shape Zig Zag Anchor. This blog explores its design features, key benefits, and where it is most commonly applied.
What is an SS 310 V Shape Zig Zag Anchors?
The SS 310 V Shape Zig Zag Anchor is a specially designed metallic anchor made from Stainless Steel 310, used to secure refractory linings to the internal shell of furnaces, kilns, reactors, and other heat-intensive equipment. The V shape provides structural support, while the zig-zag profile increases surface area and mechanical interlock with the refractory material.
This design not only enhances the holding strength but also reduces the chances of refractory material detachment or cracking during thermal expansion and contraction.
Material Advantage: Why Choose SS 310?
Stainless Steel 310 (UNS S31000) is an austenitic alloy known for its outstanding resistance to high temperatures and oxidation. It is composed of approximately:
Chromium: 24–26%
Nickel: 19–22%
Iron: Balance
These properties make SS 310 ideal for environments where the anchor must withstand:
Extreme temperatures (up to 1100°C)
Thermal cycling
Oxidizing and carburizing atmospheres
Corrosive industrial conditions
Design Features of V Shape Zig Zag Anchors
V Shape: Offers balanced support and flexibility under thermal stress.
Zig Zag Pattern: Enhances mechanical bonding with the refractory material, preventing slippage and detachment.
Customizable Geometry: Available in various sizes, thicknesses, and angles to suit different lining thicknesses and application requirements.
Key Benefits
Superior Heat Resistance
SS 310 maintains its strength and structure even at elevated temperatures.
Improved Mechanical Bonding
The zig-zag design creates a strong grip between the anchor and the refractory lining.
Minimized Refractory Failure
By allowing thermal movement and reducing stress points, it extends the service life of linings.
Corrosion and Oxidation Resistance
Ideal for both oxidizing and mildly reducing environments in industrial settings.
Easy Installation
Suitable for welding or stud-welding, depending on equipment design and site requirements.
Industrial Applications
The SS 310 V Shape Zig Zag Anchor is extensively used across multiple industries where thermal and mechanical stress is high:
Petrochemical Plants – Furnaces, reformers, and reactors
Power Generation – Boilers, incinerators, and heat recovery units
Cement & Lime Kilns – Rotary kilns, preheater towers, and calcining zones
Steel & Foundries – Soaking pits, reheating furnaces, ladles, and tundishes
Waste Management – Incinerators and ash handling systems
Customization Options
Manufacturers typically offer custom fabrication for:
Leg length and angle
Material thickness
Coating options (if needed for extreme chemical exposure)
Welding compatibility
Conclusion
The SS 310 V Shape Zig Zag Anchor is a critical component in modern refractory lining systems. Its robust design and high-temperature performance make it an industry standard in demanding thermal environments. By choosing the right anchoring system, industries can enhance the safety, durability, and performance of their refractory installations.

Frequently Asked Questions (FAQs)
What are SS 310 V Shape Zig Zag Anchors?
SS 310 V Shape Zig Zag Anchors are specialized metallic anchoring components used to support refractory linings in high-temperature industrial applications. Made from Stainless Steel 310, these anchors offer excellent resistance to oxidation, corrosion, and heat scaling, even in temperatures exceeding 1000°C. Their zig-zag pattern enhances mechanical interlocking with the refractory material, ensuring better retention and structural stability.
Why is SS 310 the preferred material for these anchors?
Stainless Steel 310 is an austenitic alloy known for its superior high-temperature strength and resistance to oxidation. It contains high levels of chromium (24–26%) and nickel (19–22%), making it ideal for environments exposed to extreme heat, such as furnaces, kilns, and reactors. This ensures long service life and low maintenance in demanding conditions.
What is the benefit of the V Shape and Zig Zag design?
The V Shape provides a stable anchoring point with good load distribution, while the Zig Zag pattern increases surface area and mechanical interlocking with the refractory material. This dual design minimizes the risk of refractory slippage, cracking, or detachment during thermal cycling or mechanical vibration.
Where are SS 310 V Shape Zig Zag Anchors typically used?
These anchors are widely used in:
Petrochemical plants
Cement and lime kilns
Power generation boilers
Steel reheating furnaces
Incinerators and reactors
Their reliability in high-stress environments makes them indispensable for lining support in these sectors.
How are these anchors installed?
SS 310 V Shape Zig Zag Anchors are typically welded or stud-welded to the metal shell of a vessel or furnace. Once in place, they hold the castable or brick refractory lining securely, ensuring it stays intact under thermal and mechanical stress.
Are custom sizes and shapes available?
Yes. Manufacturers often offer custom fabrication based on the refractory lining thickness, application type, and load conditions. Options in leg length, angle, and pattern can be tailored to meet specific engineering requirements.
