OVERVIEW

Detect Grinding Burns and Surface Defects with Nital Etch

Ensure the integrity of your machined and welded steel parts with this professional Nital Etch Test Kit. Designed for practical shop floor and quality control use, this kit allows fabricators and inspectors to quickly identify surface defects that are invisible to the naked eye. Known as "temper etching," this process is essential for verifying that grinding, machining, or welding processes haven't introduced excessive heat that could compromise the strength of the material.

When steel is ground too aggressively, the friction generates heat that can retemper or re-harden the surface, creating "soft spots" or brittle zones known as grinding burns. This kit reveals those zones by chemically treating the surface. The Nital solution reacts differently to the burned areas compared to the base metal, creating a visual contrast (often appearing as dark or light patches) that flags the defect. This is crucial for critical components like gears, shafts, and bearings where surface hardness is vital for longevity.

The kit is easy to use and comes with three 500ml bottles to cover the entire process:
1. Etch: The Nital solution is applied to the clean surface to initiate the reaction.
2. Clean: The Hydrochloric Acid solution removes any dark smut or oxidation byproducts that form during etching, ensuring you can see the pattern clearly.
3. Neutralize: The Neutralizer stops the acid from eating further into the metal and makes the part safe to handle and store.

Ideal for welding shops, machine shops, and maintenance departments, this kit helps you meet strict customer specifications, including AMS and MIL-STD requirements. Don't leave surface integrity to chance; use the Nital Etch Kit to validate your processes and deliver defect-free steel components.

FAQ

The kit contains three 500ml bottles: one Nital Etch solution, one Hydrochloric Acid solution for de-smutting, and one Acid Neutralizer solution.

This kit is designed to meet the requirements of AMS 2649 C (Etch Inspection of High Strength Steel Parts) and MIL-STD-867 C.

The Hydrochloric Acid solution is used for de-smutting. It removes the dark residue (smut) that can form on the steel surface during etching, allowing for a clear visual inspection.

Nital etch is primarily designed for carbon steels and low-alloy steels. It is generally not effective for stainless steels, which require different etchants.

Grinding burns are localized areas of thermal damage on a steel surface caused by excessive heat during grinding. They can lead to soft spots or re-hardening, which this kit helps detect.

The neutralizer stops the chemical reaction of the acid. Without it, the acid could continue to eat into the metal, causing pitting or corrosion after the test is finished.

Yes, the kit contains acids and should be handled with appropriate Personal Protective Equipment (PPE), including gloves and eye protection.

Each of the three solutions in the kit comes in a 500 ml bottle.
