19. Material Specification Table
Recommended materials
Highly alloyed austenitic Cr-Ni-steels and Cr-Ni-Mo-steels, for example in accordance with
EN 10088-1, EN 10088-2 and EN 10088-3, or stainless steel 304, 304L, 316 and 316L in
accordance with ASTM A240, ASTM A276 and ASTM A312. The outside body and baffles
of the exhaust silencers/catalysts must be made from high quality steel such as DX53D +
AS120. The exhaust before the dosing module may be of different material due to no
contact with DEF. Dosing module mounting points may be made from a different type of
metal such as X2CrNi.
Ni-Mo-Cr-Mn-Cu-Si-Fe alloys, e.g. hastelloy
Polyamide (PA12), free of additives
Polyethylene, free of additives
Polypropylene, free of additives
Polyisobutylene, free of additives
Perfluoroalkoxyl alkane (PFA), free of additives
Polyfluoroethylene (PFE), free of additives
Polyvinylidenefluoride (PVDF), free of additives
Polytetrafluoroethylene (PTFE), free of additives
Copolymers of vinylidenefluoride and hexafluoropropylene, free of additives
Rubber hose / o rings / seals
All fasteners must be DEF resistant and made of materials given in this list
NOTE 1: The sequence given in this list does not constitute a ranking of the recommended
materials.
NOTE 2: Materials made of plastics can contain various kinds of additives used either for
processing or for special kinds of serviceability. These additives can possibly migrate into
DEF. For this reason, you need to test the contamination of DEF by additives from plastic
materials used in direct contact with DEF.
Non-recommended materials
Materials forming compounds as a result of reaction with ammonia, which may negatively
interfere with the SCR converter system: carbon steels, zinc coated carbon steels, mild iron
Non-ferrous metals and alloys: copper, copper alloys, zinc, lead
Solders containing lead, silver, zinc or copper
Aluminium, aluminium alloys
Magnesium, magnesium alloys
Plastics or metals coated with nickel
