This product is designed for macro etching of stainless steel welds. It works well with 300 series stainless steels and others SS grades (see examples here). It will show the weld nugget and penetration depth. The cross-section surface needs to be polished with at least 600 grit abrasives.

 

User Instructions:

• To etch a corrosion resistant alloy, the metal surface has to be etched immediately after polishing and cleaning without any delay. Otherwise, the metal surface will passivate.

• Immerse or swab the polished surface few seconds to a minute.

• Lightly buff the etched area with alumina compound will remove some smut and reveal weld features (example).

Packaging:

Nalgene® Leakproof Bottle, HDPE.
