Select 4130LN

Low Alloy / Flux Cored / Gas Shielded


Features

  • Select 4130LN is a basic flux cored electrode for use with Ar-25% CO₂ shielding gas.
  • This electrode is designed to weld 4130, and other steels of similar composition, such as 4140 and 8630. Also commonly used to repair casting.
  • Provides a close match to steel properties following a required post weld heat treatment.
  • The deposit contains less than 1% nickel making this electrode suitable for most oil field applications.
