CORODUR® TS 309 L MO
CLASSIFICATION
T 23 12 2 L R M 3 ( C3 )
T 309 L Mo T0 1- 4
1.4459
GENERAL CHARACTERISTICS
Flux cored wire with an alloyed core, suitable for joining difficult-to-weld steels and for corrosion-proof claddings. An austenitic weld metal (Cr Ni Mo 18/ 10/ 2) is obtained already in the first layer. The alloy is also suitable for welding buffer layers on plated metal sheets and for joining austenitic to ferritic steels which are subject to service temperatures of up to 350° C. Due to its high alloy level CORODUR TS 309 L Mo produces crack-proof welds. The addition of molybdenum ensures higher corrosion resistance and higher tensile-strength at elevated temperatures, as compared to the moly-free material 1.4829. The weld metal is heat resistant and non-scaling up to 1050° C.
