Product Definition: The Smart Charge for Demanding Melts
Our Pure Iron Remelting Material is engineered for one purpose: to be the cleanest, most efficient base charge for your furnace. It is the optimal starting point for producing high-quality alloy steels, ductile iron, superalloys, and other specialty metals where control over tramp elements and gases is critical.
Core Composition & Advantages for Remelting
|
Parameter |
Our Material |
Benefit in Your Furnace |
|
Fe Base Purity |
99.7% min. |
Provides a predictable, low-impurity foundation for alloying. |
|
Oxygen (O) |
≤ 60 ppm |
Drastically reduces oxide inclusions, leading to cleaner metal and fewer defects. |
|
Hydrogen (H) |
≤ 1.8 ppm |
Prevents hydrogen-induced porosity (pinholes) in castings. |
|
Nitrogen (N) |
≤ 45 ppm |
Avoids nitride formation, stabilizing mechanical properties. |
|
Sulfur (S) |
≤ 0.008% |
Minimizes slag volume and prevents hot tearing, saving on flux additives. |
|
Carbon (C) |
0.02% - 0.05% |
Allows for precise and economical carbon adjustment. |
|
Form |
Lumps (10-50kg) / Compressed Briquettes |
Optimized for efficient furnace charging and rapid melting. |
Our Manufacturing & Quality Control
Source Control:Produced from selected premium scrap and primary iron under strict specifications.
Degassing Process: Treated with advanced vacuum degassing technology to achieve ultra-low gas levels.
Processing: Carefully processed to control size and minimize surface oxidation.

Target Applications & Industries
Premium Alloy Steel Production: Tool steels, stainless steels, electrical steels.
High-Quality Casting: Ductile iron, compacted graphite iron (CGI), and high-performance gray iron.
Superalloy & Special alloy manufacturing: As a pure iron base for nickel and cobalt-based alloys.
Welding Wire Production: As a raw material for manufacturing high-grade welding wires.
Q: How is the material packaged to prevent rust during storage?
A: Standard packaging is in bulk bags or on wooden pallets. We apply a light, industry-standard anti-rust oil that burns off cleanly during melting without affecting furnace chemistry or air quality. For critical applications, we can provide material with a minimal oil coating or discuss alternative options.
Q: Can you supply material with even lower gas content for vacuum induction melting (VIM)?
A: Absolutely. We offer a "VIM-Grade" with guaranteed O₂ ≤ 30ppm and H₂ ≤ 1.5ppm. Please specify this requirement when requesting a quote for vacuum melting applications.
