GTAW
  • MANGANESE STEELS

Description

Rod for dissimilar welds and cushioning layers.
For mixed welding applications, including the welding of C-Mn steels, stainless steels, hardenable steels, and armor plating to each other or amongst themselves. Also suitable for depositing relaxing cushioning layers on base metals that are crack sensitive and for performing hardfacing tasks. The welded metal has a high degree of corrosion resistance and withstands operating temperatures up to 300°C and will not scale up to 850°C. Hot cracking resistance is provided by the high manganese content. The increased silicon results in greater fluidity of the weld pool to impart a uniform appearance to the deposit.
