Is stainless steel magnetic? Everything you need to know.

Are you looking for a clear explanation of stainless steel and magnetism because you need a suitable chain, hook, or link? Do you already know exactly what you're looking for, or are you still exploring the options? In this blog post, we'll take you step by step: when is stainless steel magnetic, what does that mean in practice, and what to consider when buying and ordering these products for your project.

Short answer to the main question: Stainless steel can be magnetic, but that depends on the alloy type and the processing. Some stainless steels are not inherently magnetic, but can become slightly magnetic through deformation or welding. Sound confusing? Don't worry—we'll explain it clearly below and link it to recognizable applications.

Stainless steel and magnetism in brief

  • Austenitic stainless steel (e.g., AISI 304/A2 and AISI 316/A4) is virtually non-magnetic in its annealed state. However, it can become slightly magnetic through cold working (bending, drawing, rolling).
  • Ferritic and martensitic stainless steel (e.g. AISI 430 or AISI 410/420) are magnetic.
  • Duplex stainless steel is usually (partly) magnetic due to its microstructure.

What does this mean in practice? A magnet test is useful as a quick indication, but not a panacea. A 316 (A4) chain or hook can still exhibit a very slight attraction if the product has been significantly deformed or welded. Do you absolutely want non-magnetic properties? Then the type selection and product finish are especially important.

Uses and Benefits: What do you use these products for?

Stainless steel is a daily fixture in the world of fastening, lifting, hanging, and securing. Think of:

  • Outdoor and maritime applications: scaffolding, ship fittings, garden structures, and outdoor lighting. Stainless steel 316 (A4) is often chosen for this purpose because of its excellent corrosion resistance, even in saltwater.
  • Interior and decoration: hanging lamps, plants, or signage. Stainless steel is popular here for its sleek appearance, strength, and durability.
  • Sports and industry: punching bags, chain suspensions, machine environments where strength and wear resistance are important.

A major advantage of this category is the combination of strength, long lifespan, and a neat finish. The fact that you sometimes encounter magnetic properties doesn't say anything about the quality or corrosion resistance; it's mainly a matter of material type and processing. Where do you primarily use these products—outdoors, indoors, or near chlorine or seawater?

Tip: Looking for chains? Browse our extensive chain collection and easily filter by material and size. Prefer to go straight to stainless steel solutions? Then 316 (A4) stainless steel is often the safe choice for harsh or maritime environments.

Practical tips and considerations when purchasing or using

What should you consider when purchasing? The checklist below will help you choose quickly.

  1. Determine the environment
    • Maritime, swimming pools or salty air: preferably choose stainless steel 316 (A4) because of its higher corrosion resistance.
    • Indoor or light outdoor use without heavy loads: stainless steel 304 (A2) may suffice.
    • Wondering if your situation is "severe"? Consider regular exposure to brine, chlorine, or acids. Still unsure? Feel free to contact us.
  2. Magnetism: important or not?
    • Does the product absolutely need to be non-magnetic (e.g., around sensitive equipment)? Choose austenitic stainless steel and avoid strong cold-working. Be aware that even austenitic stainless steel can sometimes become slightly magnetic after processing.
    • Is magnetism not a problem? Focus on the correct strength, fit, and corrosion resistance.
  3. Check the material code
    • A2 = Stainless steel 304 (usually non-magnetic, may attract light after deformation).
    • A4 = Stainless steel 316 (usually non-magnetic, extra corrosion resistant).
    • Do you see AISI or DIN references? This will help you select the correct version. Are you unsure about the code on the product page?
  4. Choose the right size
    • Thickness, link size, breaking load, and working load are crucial. Choosing a version that is too light can lead to faster wear or deformation.
    • Do you need help converting or estimating your tax? Let us know your application and we'll be happy to help.
  5. Testing in practice
    • A simple magnet test provides an indication, but it's not proof of quality. Use it as a check, not as a standard.
    • Use appropriate accessories, such as link chains, snap hooks and S-hooks of matching material, to prevent galvanic corrosion.

Looking for a complete package for your hanging or mounting project? Combine these products with matching accessories in the same material to ensure the perfect fit and a neat, durable finish.

Conclusion: is stainless steel magnetic?

It depends on the stainless steel grade and processing. Austenitic stainless steels such as 304 (A2) and 316 (A4) are generally non-magnetic, although slight magnetic attraction can occur through deformation or welding. Ferritic and martensitic stainless steels are magnetic. Important to remember: magnetic behavior does not indicate corrosion resistance. For outdoor and marine applications, 316 (A4) is often the best choice.
