SUPERCITO Carbon & Carbon manganese steel

STANDARDS:

AWS A5. 1: E 7018

EN 499: E42 6 B 42 H10

SUPERCITO

APPLICATIONS/ PROPERTIES:

Basic type electrode with 115% metal recovery.

Suitable for C and C- Mn steels where high

mechanical and crack- resistant properties are

required. Good all positional weldability and

easy slag removal.
