EN 1600: E 18 8 Mn R 32
DIN 8556: E 18.8 Mn R 26
ISO 3581: E 18.8 Mn R 32
NFA 81-343: EZ 18.8 MnR 26
FEATURES & APPLICATIONS |
For reclaiming and joining 14% manganese steels, as well as non-alloy and alloy structural and heat treatable steels.
- Non-synthetic, non-magnetic, high manganese stainless for joining and buffer layers.
- “Non-magnetic” weld metal is not susceptible to cracking and possesses high deformation capacity.
- Joins armor steels to themselves as well as to mild, stainless and manganese steels.
- Offers a rare combination of toughness, crack resistance and impact resistance.
- Easy and complete slag removal.
