$66.62

Description

Stainless Steel Weld Etch is a general-purpose stainless steel etchant formulated by our metallurgist, which is designed to macro-etch all common grades used in the welding industry. It works very well with 300 series and other stainless steel grades (see list of examples here), showing the weld nugget clearly for the penetration depth analysis. Unlike Lepito’s Etch or Aqua Regia, this product is pre-made, ready to use, no mixing or heating required; furthermore, it can be stored up to a year. Made with reagent grade chemicals.

 

User Instructions:

  • This product has a minimum surface finish requirement, please grind and polish the cross-section to at least a 600 grit finish before etching.
  • To etch any corrosion resistant alloy, the metal surface has to be etched immediately after polishing and cleaning without delay. Otherwise, the prepared surface will oxidize and 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.
