Stainless steels

For all operating conditions

A corrosive environment, plus high operating temperatures and demanding mechanical loads? Our stainless acid- and heat-resistant steels are the right choice for your application.

The range of applications is diverse and extends from the chemical and petrochemical industry to mechanical engineering and the onshore and offshore sector. But also in energy and environmental technology, medical technology or the food industry, our stainless and heat-resistant steels meet the highest mechanical and corrosion-chemical requirements.


Highest purity and audited heat treatment processes

Whether austenite, ferrite, martensite or duplex steel - the optimised chemical composition of our grades combined with high purity and a defined heat treatment (CQI9 / API 6a) guarantee homogeneous properties and long-lasting products.
For the highest requirements, remelting is possible via our modern ESR, PESR and VAR remelting units.

Versatile and flexible in use

BGH martensitic, stainless and heat-resistant stainless steels impress with their combination of strength, wear resistance and corrosion resistance and the diversity of their applications.

With our wide range of carbon and nickel-martensitic steels, we have the right material for your application, whether in vehicle construction, medical technology, machine and equipment construction, the chemical industry and petrochemistry, energy technology, turbine construction or in the field of sensor technology. Areas of application are shafts, drives, screws, knives, surgical instruments, valves, fittings and much more.

BGH martensitic steels

Strength meets corrosion resistance

BGH Superduplex and Duplex steels, with their unique combination of properties of strength, corrosion resistance and ductility even at low application temperatures, are proven and reliable materials for your industrial application.
The emerging hydrogen industry, onshore and offshore industries, pipeline and tank construction, the chemical and petrochemical industries or the pulp and paper industry are just some of the application areas where our grades have been reliably in use for years.

With the Norsok M-650 approval, we meet the highest quality standards for our duplex grades in terms of expertise, plant and process engineering and our control systems.

BGH superduplex/duplex steels

Tailor-made properties and cost efficiency

Properties such as good resistance to stress corrosion cracking, high thermal conductivity with low thermal expansion and good formability, all coupled with high cost-effectiveness: these are ferritic steels from BGH.

The high surface qualities that can be achieved guarantee the highest hygienic standards for applications in the food and beverage industry, gastronomy, medical technology and household appliances. But ferritic steels are also used for fasteners, in plant and mechanical engineering or in exhaust systems.

BGH ferritic steels

Exceptional corrosion resistance for very high or very low application temperatures

Resistance to corrosion, for low and high temperature applications with excellent machinability - BGH austenitic steels are very versatile.

With our precise heat treatment, we create a precipitation-free and homogeneous microstructure, the basis for reliable workability and optimal operating properties, e.g. as an efficiently machinable material for shafts in kitchen machines or as a temperature-resistant wire conveyor belt in industrial continuous furnaces. In medical technology, BGH austenitic grades are used for components for asthma inhalers, among other things.
