Hardfacing Welding Electrodes
HF450 - Isoarc HF450

Characteristics
ISOARC HF 450 is a basic coated AC/DC all position electrode, depositing a weld containing chromium, nickel and molybdenum. The weld metal, which comprises metallic carbides in a martinsetic matrix, has a hardness of 420-480HV(43-48HRc). The weld metal provides good resistance to abrasion and impact loads in wet and dry conditions.

Applications
This versatile electrode is suitable for use in applications where frictional loads and metal to metal wear conditions occur. The weld metal is extremely resistant to breakout or spalling, which makes it eminently suitable to use on permanent way crossings, rail ends, excavator bucket lips, tractor drive wheels, etc. The deposit, which is machinable with carbide tipped tools, is also suitable for use as a low cost buffer layer for the deposition of high alloy wear resistant deposits.
