Our automotive application tubes embrace optimising present internal combustion based platforms whilst actively developing material solutions for electric and hydrogen based technologies.
From fuel economy to emission control systems we provide material solutions in round tubes, hollow bars profiles and components:
High strength to weight – stronger and lighter
Our process control and ability to refine cold worked properties combined with a range of high strength martensitic, duplex and nickel alloys ensures we can optimum strength-to-weight properties.
Profiles and reproducibility
Adding value, adding service. Square, rectangle, oval or as requested by customer drawings.
Machinability
Our range of hollow bar combined with VALIMA TECHNOLOGY for improved machinability.
Our global, integrated, production facilities ensure full control from melt onwards to ensure optimum control of properties, from melt refinement to produce VALIMA improved machinability hollow bars to duplex stainless steels combining weight savings with corrosion resistance properties.

Service:
From prototypes to full scale volume production our global production facilities offer both flexibility and cost competitiveness.
Hydrogen
The hydrogen economy represents the strategic development of hydrogen production, transport, infrastructure usage towards a 2050 view of the complete conversion to hydrogen as our primary source of mobility fuel.
To supply energy to fuel cell vehicles which use hydrogen as the next generation clean energy requires materials with high levels of product integrity, excellent hydrogen embrittlement resistance at high pressures and low temperatures.
DMV H2ready brings our customers not only the DMV offering of stainless and nickel alloys but the much larger role the complete DMV family brings towards the future of fuel cell technology and the development of the true environmentally friendly benefits thru the conversion of renewal energy into hydrogen.
