Complex products and assemblies made of stainless steel

Arnold produces stainless steel components for medical devices and analyzers Stainless steel products

Arnold is your partner for professional stainless steel work. The company has been making products from this material for over 50 years.

Selecting the right stainless steel based upon the product requirements (durable, low-maintenance, hygienic) is critical, as the chemical composition affects the properties of the material:

  • Corrosion resistance
  • Tensile strength
  • Possibility to further process
Thanks to optimized stainless steel processing, Arnold can produce flawless surface qualities. Scratch-free stainless steel surfaces without bending marks

Stainless steel processing with high vertical integration and attention to detail

At two German locations, we produce components and welded assemblies with

  • high technical standards, low tolerances, and
  • high visual standards (e.g., design cladding for consumer goods)

Arnold can build anything from prototypes to small or large series.

We use all industry-standard sheet metal processing methods: 

  • Lasering
  • Punching
  • Deburring
  • Bending
  • Welding
  • Grinding
  • Polishing
  • Engraving
  • Screen printing
  • Electropolishing
  • Laser marking
  • Washing, cleaning
  • Final assembly

Stainless steel assemblies with complex surfaces

Whether brushed, ground, or polished stainless steel – Arnold can offer stainless steel designer products in any desired look. The perfect finish
Stainless steel surfaces can be polished down to an extremely low roughness of 0.004 µm. This makes extraordinary customer requirements possible. High-gloss polish

The final polishing and grinding step is an art that Arnold has been dedicated to for many years through the use of unique techniques and processes.

This includes

  • grinding and polishing welding seams until they are virtually invisible,
  • polishing extremely low roughnesses down to RA 0.004 µm
  • restoration of grinding patterns (e.g., K400) after processing, and
  • the gentle handling of the products in order to prevent scratches on the surface.

Stainless steel vs steel – which is better?

Steel must always be provided with a special coating (e.g., varnish) to protect it from environmental influences.

Stainless steel, on the other hand, has an extremely high degree of purity and is used when maximum corrosion protection is needed. Stainless steel does not require additional surface coating.

Furthermore, stainless steel may be more cost-effective compared with steel. Stainless steel products are also very durable and always look like new.

Is stainless steel 100% corrosion resistant?

Stainless steel in accordance with DIN EN 10020) is a designation for alloyed or unalloyed steels with a unique degree of purity. While the material is highly resistant to corrosion, it is not 100% corrosion-proof.

This is why Arnold emphasizes the prevention of crevice corrosion when working with stainless steel. It is important to plan ahead before construction starts.

Arnold designers and their expertise are at your disposal even during product development.

Does arnold process stainless steel and steel in separate areas?

In our workshops, spatial separation between these areas is very important.
This is very important from a technical point of view. Grinding and welding steel produces dust, and dust that settles on stainless steel can cause corrosion.
