Industry

Complex products and assemblies made of stainless steel

Arnold produces stainless steel components for medical devices and analyzers

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.

We

can support you with the design, especially when it comes to crevice corrosion and pickling suitability,
analyze the cost efficiency of products,
offer advice for the selection of materials,
have a wide range of processing options (e.g., lasering, bending, welding),
produce assemblies made of stainless steel at two locations in Germany and
develop individual packaging solutions for safe delivery.

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

Bending stainless steel: Arnold can produce large or small bending radii with state of the art technology and know-how.

Grinding stainless steel: The grinding of visually demanding stainless steel surfaces achieves a uniform grinding pattern without any visible welds.

Automated welding is ideal for high-volume stainless steel products with long weld seams and tight tolerances

Stainless steel assemblies with complex surfaces

Whether brushed, ground, or polished stainless steel – Arnold can offer stainless steel designer products in any desired look.

Due to its properties, stainless steel does not require an additional coat, e.g., paint.The raw material itself can be worked with.

This makes stainless steel the ideal material for assemblies that require maximum cleanliness. That includes machines used for analyzers, medical devices, and the foodstuff industry.

Stainless steel is also very popular in terms of its visual appeal and high-quality design material. Arnold uses different grinding and polishing techniques and specific stainless steel types to create a wide range of unique surface qualities.

Many years of experience in the processing of ground and polished sheet metal are needed to produce a visually flawless result. Every step of fabrication leaves behind visible traces, such as welding seams, discoloration, and interruptions in the original grinding pattern of a cross section.

Stainless steel surfaces can be polished down to an extremely low roughness of 0.004 µm. This makes extraordinary customer requirements possible.

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.
