Stainless Steel Snap Bands &Elastic Strips for Filter Bags and Industrial Sealing

High-Elasticity SUS301 & SUS316L Stainless Steel Bands – Designed for Filtration, Sealing, and Fastening Solutions

Product Overview

Engineered for high-performance filtration systems, our stainless steel snap bands deliver exceptional durability, precise fit, and reliable sealing performance. Designed to integrate seamlessly with automated riveting and welding systems, they ensure smooth feeding, stable operation, and consistent results in modern filter bag production lines.

Available in SUS301 (HV600, high elasticity & clamping force) and SUS316L (HV540, high corrosion resistance) grades, each coil is precision-slitted, bright-annealed, and optimized not only for filter bag assembly but also for broader sealing and fastening applications across multiple industries.

 Material Grades & Performance

We provide two high-grade stainless steel options tailored for industrial filtration environments:

🔹 SUS301 (Equivalent to EN 1.4310)

• Cr: 16.0–18.0% | Ni: 6.0–8.0%

• HV600 ± 15 → High hardness, strong springback & tight clamping force

• Excellent elasticity for long-term sealing without loosening

• Bright-annealed surface for enhanced corrosion resistance

• Cost-effective choice for general dust collection & sealing

🔹 SUS316L

• • Cr: 16.0–18.0% | Ni: 10.0–14.0% | Mo: 2.0–3.0%

  • HV540 ± 20 → Excellent corrosion resistance

  • Superior performance in chloride-rich, acidic, or alkaline environments

  • Ideal for flue gas desulfurization (FGD), waste incineration, and aggressive atmospheres

  💡 Test Data: SUS301 with yellow passivation treatment provides 1.5–2× better NSS corrosion resistance vs. plain BA surface — especially in sulfur-containing & humid environments.

 Fiberglass Filter Bags &High temperature Filter Bags & Corrosive Environments

Fiberglass filter bags are particularly sensitive to abrasion and edge tearing.
For these demanding conditions, SUS316L stainless steel snap bands provide superior performance:

• Excellent corrosion resistance against acids, chlorides, and moisture-laden gases

• Stable sealing even under high-temperature and high-humidity operation

• Minimized abrasion thanks to polished, bright-annealed surface finish

By contrast, SUS301 (HV600) offers high elasticity and strong springback, making it ideal for standard industrial dust collection.
However, in highly corrosive atmospheres such as FGD (flue gas desulfurization) and waste incineration, SUS301 can suffer from premature leakage, corrosion, or snap-band slippage.

To solve this industry-wide challenge, KABORY developed SUS316L snap bands as a dedicated solution for aggressive environments — ensuring long-term sealing stability and zero failure risk where 301 falls short.

 Key Features

⚠️ Automation Compatibility Matters

Most steel band suppliers overlook a critical factor: flatness and consistency across the roll.

Even minor deviations such as:

• ⚠️ Wave distortion or edge curling
• ⚠️ Thickness variation
• ⚠️ Burrs or slitting defects
  can result in:

⚠️ Misaligned feeding or jammed rollers
⚠️ Welding or riveting failures
⚠️ Mold seizure or tooling breakdowns
⚠️ Increased downtime and maintenance cost

A snap band may seem insignificant, but poor strip quality can halt an entire production line or compromise bag sealing during pulse-jet cleaning.

High springback also mitigates permanent set from repeated assembly, improving yield and consistency on automated riveting/welding lines.

📌 Case Study: The Real Cost of Poor-Quality Snap Bands

At first glance, a snap band may seem like a small, inexpensive component in the overall filter bag system. But when quality is compromised, the consequences are significant:

• Leakage & Dust Emissions
  Inferior snap bands often suffer from poor flatness, inconsistent hardness, or rough edges. This leads to incomplete sealing against the tube sheet, causing dust to leak into clean air chambers.

• Bag Slippage & Unexpected Drop-Off
  Weak bands lose their clamping force under vibration or pulse-jet cleaning. In extreme cases, entire filter bags can loosen or fall from the tube sheet — leading to unplanned shutdowns and severe safety risks.

• Accelerated Filter Bag Wear
  Snap bands with burrs or uneven surfaces can cut into the filter bag cuff, shortening the service life of bags that are otherwise designed to last years.

• Hidden Costs Outweigh “Savings”
  While low-cost snap bands may save a few dollars per coil, the cost of replacing prematurely failed bags — or worse, dealing with production downtime and environmental penalties — far outweighs the initial “savings.”

💡 When compared with the cost of filter bags themselves (often hundreds of dollars per bag) or the operational losses from unscheduled maintenance, investing in precision-engineered stainless steel snap bands is the only rational choice.

We maintain tight tolerances on material flatness, edge finish, and mechanical properties to ensure compatibility with automated production lines.

Beyond Filter Bags – Extended Applications

SUS301 stainless steel (HV600) is engineered as a high-elasticity sealing & fastening material. With superior springback, clamping force, and durability, it is trusted not only in filter bag production but also across other industries:

• Industrial sealing rings & clamps

• Fastening strips & elastic couplings for dust collection & pneumatic conveying

• Flexible duct connection systems (e.g., BFM-style fittings)

• High-resilience fastening components in chemical, power, and process industries

Where resilience, clamping strength, and reliability are critical, SUS301 & SUS316L stainless steel deliver proven performance.

 Snap Band Selection Tips

1. Corrosion Exposure: Use SUS316L in acid/alkaline or chloride-rich conditions
2. Machine Type: Confirm compatibility with your automatic snap band  riveting machine or Automatic Snap  Band Welding  Machine
3. Bag Size Fit: Match snap band width/thickness to bag diameter and groove depth
4. Media Type: Choose bright-annealed finish for laminated or fiberglass bags
5. Reliability: Select vendors who understand automation—not just metallurgy
