Oelheld U.S. recently introduced AirForge 4027, a newly developed protective lubricant for hot forging of steel and alloys.
It's designed to deliver results when metal protection against oxidation, gas diffusion and heat is required. AirForge 4027 is colorless and does not contain graphite. AirForge 4027 is diluted in water and can be used either by dipping or spraying the metal blanks.
The product is designed for a wide range of operations, even on challenging work piece shapes. It is free of lead or any other toxic components and does not contain solvents.
