What Is Industrial Pure Iron 2N & 3N?
Industrial pure iron refers to refined iron with extremely low levels of impurities. The purity grade is expressed in “N” (nines):
2N Pure Iron (≥ 99.0%) – Iron content not less than 99%, with total impurities ≤ 1%.
3N Pure Iron (≥ 99.9%) – Iron content not less than 99.9%, with total impurities ≤ 0.1%.
With excellent chemical stability, magnetic properties, and formability, high-purity iron is widely used in electronics, magnetic devices, research, and specialty industries.
Industrial Pure Iron (2N–3N Grade) Production Process
Huaxiao Metal adheres to strict standard production processes to ensure that every product meets the highest quality standards. Our key production steps include:
Raw Material Selection: We select high-purity iron ore and scrap steel to control impurity levels at the source.
Smelting and Refining: Raw materials are melted in electric or induction furnaces, and specialized refining techniques are used to remove harmful elements such as carbon, sulfur, and phosphorus to enhance purity.
Ingot Casting and Hot Processing: The refined molten iron is cast into ingots, which are then hot-rolled or forged to form preliminary plates, bars, or wire.
Cold Processing and Finishing: Semi-finished products undergo further processing, such as cold rolling, wire drawing, and annealing, to achieve the customer’s desired dimensions and mechanical properties. Finally, surface treatment and packaging are performed.
Key Features & Advantages of Industrial Pure Iron (2N–3N Grade)
Stable Chemical Composition: Our 2N/3N industrial pure iron offers Fe content ranging from 99.5% to 99.94%, with strictly controlled impurity levels to ensure stable and consistent product performance.
