OK Autrod 2504
A ferritic stainless steel solid wire with approximately 15 % austenite, high carbon content and 25 % Cr for welding similar and matching heat resistant ferritic-austenitic and ferritic steels. OK Autrod 2504 is developed and designed for the automotive industry and used for production of exhaust systems where oxidizing and sulfur containing combustion gases are expected. The wire has excellent welding properties and should be used when there is a need for very good resistance to corrosion and thermal fatigue. Resistant to scaling up to 1100°C. OK Autrod 2504 is suitable to use when welding base material 1.4821 / X15CrNiSi25-4; 1.4823 / GX40CrNiSi27-4 1.4713 / X10CrAlSi7; 1.4724 / X10CrAlSi13; 1.4742 / X10CrAlSi18; 1.4762 / X10CrAlSi25; 1.4710 / GX30CrSi7; 1.4740 / GX40CrSi17; ASTM A 297 Gr. HC, HD; AISI 327.
