We are on hand to advise you on the choice of material and answer any questions you may have about corrosion, heat or surface treatment.

Avoid corrosion

The aim of processing stainless alloys is to prevent corrosion. BUTTING processes a variety of steels, alloys and clad materials of different grades to counteract almost every possible form of corrosion in a wide range of industries. The right choice depends on the conditions of the subsequent application.

Customised for every application

Wide range of high-performance materials

We offer you optimal, customised solutions for piping systems, tanks and special components as part of your special project. With our proven expertise in materials technology, we are your reliable specialist for processing austenitic steels, special alloys and titanium as well as duplex, superduplex and lean duplex.

Austenitic steels
Austenitic steels are primarily used in the chemical and pharmaceutical industries, in the paper and pulp industry and for household appliances. They are also used in food and beverage production and processing, in apparatus and container construction.
Austenitic-ferritic steels
Austenitic-ferritic steels, known as duplex steels, are ideal for almost all offshore installations, such as vessels and process pipes on drilling platforms or for use in seawater desalination plants.
Nickel alloys
The nickel alloy group has excellent localised and acid corrosion resistance. This benefits many applications, particularly in the chemical and pharmaceutical industries as well as in oil and gas production.

Reacting to circumstances

Corrosive media

Chloride-containing attack agents
For stresses in connection with halogen ions (chlorides, fluorides, iodides, bromides), we recommend the use of steels with increasing chromium and molybdenum contents. Copper-nickel alloys, high-molybdenum nickel alloys and titanium are suitable.
Sulphuric acid attack agents
Molybdenum and copper additives can help to reduce the concentration of sulphuric acid. Chromium and silicon have proven themselves as corrosion protection against oxidising sulphuric acids. Lead linings and nickel alloys are suitable for special stresses.
Phosphoric acid attack agents
Austenitic molybdenum-alloyed steels have proven their worth, particularly in the aggressive environment of pure phosphoric acids, even in high temperature ranges. In contrast, highly alloyed special steels should be used in contaminated phosphoric acids.
Organic corrosive agents
Stainless steels are resistant to a large number of organic solvents and chemicals such as greases, oils, benzene, phenols and other carbon-hydrogen compounds In addition, unlike unalloyed steels, they are not contaminated by traces of rust.
