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.
