Nital Solution %3 | Nital Etchant | ASTM E407

The Nital Solution %3 is specifically designed for metallurgical applications requiring a faster, more aggressive etch rate than standard 1% or 2% solutions. This increased concentration drastically reduces immersion times, making it the superior choice for high-capacity industrial laboratories and busy production floors where rapid turnaround is critical.

Beyond standard microstructural analysis, the 3% formulation excels in macroscopic examinations. It provides the deep etching necessary to clearly visualize structural flow lines, heavy segregation, and widespread defects across larger specimen surface areas.

Certified ASTM E407 Compliance

Rigorous standardization is non-negotiable in professional quality assurance. Gündüz Kimya produces the 3% Nital Solution in absolute strict adherence to ASTM E407 (Standard Practice for Microetching Metals and Alloys).

By utilizing our ASTM-certified 3% etchant, metallurgical laboratories ensure that their accelerated testing protocols still generate data that is fully compliant with global standards.

Nital Solution %3 Applications & Uses

Our 3% Nital Etchant provides highly efficient performance for specific high-demand metallurgical tasks:

• Low-Carbon Steels: Highly effective at revealing the grain boundaries and structures in low-carbon alloys where lower concentration etchants may act too slowly.

• Rapid Production Testing: Accelerates the etching process for routine quality control in continuous manufacturing lines.

• Macro-Etching & Weld Profiling: Delivers the deep, high-contrast etch required for macroscopic evaluation of large weld cross-sections, distinctly revealing the weld nugget, fusion line, and Heat Affected Zone (HAZ).

• Forging & Casting Analysis: Ideal for exposing flow lines, dendritic structures, and gross macro-defects in cast or forged components.

Nital Solution %3 Flexible Packaging to Suit Institutional Demands

To support the diverse operational requirements of industrial testing facilities, our Nital Solution 3% is supplied in robust, chemically inert packaging:

• 250 ml Bottle: Suitable for specialized macro-testing kits, academic demonstrations, or secondary testing stations.

• 500 ml Bottle: The standard size for high-throughput daily laboratory operations requiring rapid chemical turnover.

• 1 Liter (1000 ml) Bottle: The optimal, cost-effective solution for heavy industrial applications, foundries, and large-scale quality control departments.

Why Choose Gündüz Kimya’s Nital Solution %3 ?

Safety & Handling Information: > Nital solution is a flammable and corrosive chemical mixture. Due to the higher acid concentration, extreme care must be taken. Always use appropriate Personal Protective Equipment (PPE), including heavy-duty chemical-resistant gloves, splash goggles, and a lab coat. Use strictly in a well-ventilated area or under a certified laboratory fume hood. Store securely in a dedicated corrosive/flammables safety cabinet, away from direct sunlight, heat, and incompatible materials. Please consult the comprehensive Safety Data Sheet (SDS) provided by Gündüz Kimya prior to use.
