Outokumpu LDX 2101 material has received official approval for use in building pressure equipment. While utilizing LDX 2101 having dimensions less than 10 mm, manufacturers may check the European Approval of Material (EAM) to meet the specifications set by the European Pressure Equipment Directive (PED).
On 27 March 2012, it was publicly declared in the Official Journal of the European Union (OJEU) that lean duplex received the European Approval of Material.
According to the Pressure Equipment Directive, materials utilized in pressure equipment must essentially:
- have the particular material appraisal (PMA); or
- stick to a harmonised standard material; or
- be covered by an EAM
A PMA will demonstrate that the applications, which are fabricated using LDX 2101 in other dimensions less than 10 mm, will meet the specifications set by the European Pressure Equipment Directive.
According to Claes Tigerstrand from Outokumpu Avesta Research Centre, the accomplishment of the European Approval of Material supports and allows fabricators to easily utilize the LDX 2101 in pressure equipment, and this may create opportunities for the company’s innovative projects.
Outokumpu specifically developed and patented LDX 2101, a lean duplex grade material. This material has low nickel content and is two times stronger when compared to standard austenitic grade like 304. It is a good corrosion-resistant material and has been successfully used in challenging applications across the globe.
