Mac Stain E120
25.6.2.L.R.
Descriptions & Applications:
Designed on a highly alloyed core wire with a high purity lime/rutile flux coating that deposits high chromium duplex weld metal with excellent resistance to corrosion and erosion. After water quenching from 1100°C the microstructure is 30 to 40 % delta ferrite – balance austenite.
Mac Stain E120 is designed to weld alloys in cast condition which are then solution heat treated at 1100°C and then air or water quenched.
These alloys include AISI 329, DIN 1.4460 and 1.4582 and propriety alloys such as Firth Vickers FMN, Weir Materials Xeron 25, Sandvik 10RE51 and 3RE60.
