Abracrom 309Mo
Stainless electrode for repairing
Description & applications
Low carbon rutile-basic coated 23Cr 12Ni 2Mo stainless steel type electrode used to weld on 316L cladded steels and for dissimilar joints between construction / mild steels and stainless steels. Intermediate layer for a 316 L type cladding. Due to its high level of delta ferrite also used as a universal repairing electrode in maintenance welding. Highly cracks resistant. Soft fusion, nice aspect of the bead, slag lifts by itself.
Stainless steels:
NF A 35-578 : Z 15 CND 24.13, Z2 CND 1712, Z6 CND T 17.12
AISI : 316 L, 316 Ti, 316 Cb
Werkstoff Nr : 1.4401, 1.4404, 1.4571
+ All sweet steels type, half-hard, low alloyed in combination with stainless steels types.
