Nital Solution %2 | Nital Etchant | ASTM E407
The Nital Solution %2 serves as the optimal general-purpose etchant for a vast majority of ferrous metal examinations. Compared to lower concentrations, our 2% formulation offers a slightly faster etch rate, providing exceptional contrast between ferrite and pearlite phases in a shorter immersion time. This makes it highly efficient for laboratories processing large volumes of samples where both speed and superior clarity are required.
Whether performing routine metallurgical assessments, production line quality control, or comprehensive defect analysis, the 2% Nital solution guarantees sharp, highly definitive grain boundaries for accurate microscopic evaluation.
Certified ASTM E407 Compliance
Accuracy and reproducibility are fundamental to professional metallurgical analysis. Gündüz Kimya formulates the 2% Nital Solution in strict adherence to ASTM E407 (Standard Practice for Microetching Metals and Alloys).
By integrating an ASTM-certified etchant into your laboratory protocols, you ensure that all microstructural documentation, grain sizing, and phase analysis fulfill stringent international quality standards.
Nital Solution %2 Applications & Uses
Our 2% Nital Etchant is precisely balanced for optimal performance across diverse metallurgical applications:
-
General Ferrous Alloys: The go-to etchant for revealing the general microstructure of plain carbon steels, structural steels, and tool steels.
-
Phase Identification: Delivers outstanding contrast for identifying martensite, bainite, pearlite, and ferrite structures in heat-treated components.
-
Macro-Etching & Weld Analysis: Highly effective for macroscopic examination of weld joints, rapidly defining the weld metal, fusion boundary, and Heat Affected Zone (HAZ).
-
Surface Hardening Evaluation: Provides clear visual distinction for measuring effective case depths in induction hardened, carburized, or nitrided steel parts.
Nital Solution %2 Flexible Packaging to Suit Institutional Demands
To accommodate the varying throughput requirements of different institutions, our Nital Solution 2% is packaged in chemically inert, high-security containers:
-
250 ml Bottle: Ideal for specialized research, low-volume testing stations, or mobile quality inspection units.
-
500 ml Bottle: The standard configuration for daily laboratory workflows and continuous sample preparation.
-
1 Liter (1000 ml) Bottle: The premier choice for high-capacity industrial laboratories maximizing operational efficiency and cost-effectiveness.
