Nital Solution %10 | Nital Etchant | ASTM E407
The Nital Solution %10 is an extreme-duty formulation designed almost exclusively for macroscopic evaluation rather than standard microscopic examination. Due to its highly aggressive chemical nature, it rapidly attacks the metal surface, making it the ultimate choice for deep-etching large ingots, billets, heavy continuous castings, and massive forgings.
This concentrated solution instantly exposes structural flow lines, severe porosity, deep cracks, and widespread inclusion fields that lower concentration etchants cannot effectively reveal. It is an indispensable tool for heavy industrial foundries, failure analysis laboratories, and raw material inspection facilities.
Certified ASTM E407 Compliance
In rigorous heavy-industry testing environments, uncompromising standard compliance is vital. Gündüz Kimya manufactures the 10% Nital Solution in strict adherence to ASTM E407 (Standard Practice for Microetching Metals and Alloys) and related macroscopic testing protocols.
By integrating our ASTM-certified 10% etchant into your heavy-duty inspection procedures, you ensure that your macro-structural documentation and defect reporting seamlessly align with the stringent requirements of ISO 9001, IATF 16949, and ISO/IEC 17025 Quality Management Systems.
Nital Solution %10 Applications & Uses
Our 10% Nital Etchant delivers extreme chemical action for the most demanding metallurgical assessments:
-
Intensive Macro-Etching: The definitive choice for deep-etching large-scale steel components to visually expose primary solidification structures, dendritic growth, and ingot segregation.
-
Severe Defect Identification: Rapidly highlights macro-defects such as extreme porosity, shrinkage cavities, flaking, and deep thermal cracking in heavy forgings.
-
Highly Resistant Alloys: Capable of breaking down the surface passivity of certain highly alloyed, corrosion-resistant ferrous materials that do not respond to standard 1%–5% Nital.
-
Heavy Weld Macro-Profiling: Provides exceptionally deep contrast for the macroscopic evaluation of massive, multi-pass industrial weld joints and extreme Heat Affected Zones (HAZ).
Nital Solution %10 Flexible Packaging to Suit Institutional Demands
Given the extreme potency of this chemical formulation, our Nital Solution 10% is securely packaged in heavy-duty, chemically inert industrial containers designed for maximum safety:
-
250 ml Bottle: Designed for specialized heavy-alloy research, occasional deep-etching requirements, or highly targeted defect analysis.
-
500 ml Bottle: The standard configuration for laboratories managing consistent volumes of heavy macroscopic testing.
-
1 Liter (1000 ml) Bottle: The highly economical and efficient choice for large-scale steel mills, heavy foundries, and high-capacity raw material inspection departments.
Why Choose Gündüz Kimya’s Nital Solution %10 ?
-

Extreme Safety & Handling Warning:
Nital solution 10% is a highly flammable, exceptionally corrosive, and strongly oxidizing chemical mixture. Due to the 10% acid concentration, the reaction with metals can be violent and generate significant fumes. Extreme laboratory safety precautions are absolutely mandatory. Always use complete Personal Protective Equipment (PPE), including heavy-duty acid-resistant gloves, a face shield over safety goggles, and a heavy protective lab coat. Use strictly under a high-capacity, certified laboratory fume hood. Store securely in a dedicated corrosive/flammables safety cabinet, entirely isolated from direct sunlight, heat sources, and all incompatible organic materials. Please consult the comprehensive Safety Data Sheet (SDS) provided by Gündüz Kimya prior to use.
