Applications engineering
Markets and industries are constantly changing and with that, the demands for
the applied materials. Our proximity to the procurement and sales markets enable
us to react to changing demands and utilize the potential of latest technological
developments to the maximum.
Improved profitability by means of material savings
Steel grades with an increased yield strength lead to an application with reduced
wall thickness. Thus, material consumption goes down, and at the same time your
overall costs.
Utilizing weight-saving potentials by using high strength steels
Applications, for which weight reduction is the vital key requirement, require the use of
technologically advanced high strength steels. This enables saving weight by up to 39 %.
Increased product reliability by means of property-optimized materials
Applications, which are exposed to extreme conditions such as very low temperatures
or aggressive media, make the highest demands on the material. The selection of the
appropriate material is decisive for the quality of your product.
Fulfillment of individual high performance requirementsby means of precisely designed products
In close collaboration with leading technological steel tube manufacturers, we
support you in the development of individual steel tube products for specific
material requirements.
Technical consulting and development support
Your benefits: increased product quality and profitability
