Exaton 22.12.HTR

Exaton 22.12.HTR is a covered rutile‑acid coated stick electrode that produces a chromium‑nickel weld metal resistant to scaling in air up to 1150 °C (2102 °F). It is primarily intended for high‑temperature steels such as Alleima 253MA and Avesta 253MA, and is also suitable for AISI 309 and EN 1.4828.

Key Features

• Rutile‑acid coating for low spatter and easy slag removal
• Provides a finely rippled bead with spray transfer
• High temperature resistance up to 1150 °C
• Contains cerium in the core wire for improved performance
