Hastelloy Laser Cleaning Settings

When laser cleaning Hastelloy, start with reduced power to manage its low thermal conductivity, which causes heat to build up quickly in treated areas. This approach removes surface contaminants cleanly while preserving the alloy's exceptional corrosion resistance. But watch for uneven heating midway through—adjust scan speeds downward to avoid cracking the protective oxide layer. Multiple passes restore the finish without weakening its high-temperature strength.

Power Range

Amplifies damage risk in Pulse Width and Energy Density. Keep low to maintain safety margins.

Spot Size

Same power in a smaller spot creates much higher energy density.

Energy Density

Higher power delivers more energy per pulse, removing more material.

Pulse Width

More power means higher peak intensity. Too much can damage the material.

Pass Count

Using more passes means you can use lower power and still get the job done.
