What is the implementation standard for sponge iron? Many people may wonder about the industry standards for sponge iron. According to Zhengda Sponge Iron Network, there is currently no official national production specification for sponge iron. Instead, industry standards vary, and the final technical parameters are ultimately determined based on customer requirements.
So, what exactly are the technical specifications that customers usually require? The chemical composition can vary depending on the application. Here are some common specifications:
1. High-purity sponge iron: TFe ≥ 95%, SO₂ ≤ 0.65%, S ≤ 0.03%, P ≤ 0.03%.
2. Standard-grade sponge iron: TFe ≥ 92%, SO₂ ≤ 5.0%, S ≤ 0.03%, P ≤ 0.03%.
3. Medium-grade sponge iron: TFe ≥ 90%, SO₂ ≤ 7.0%, S ≤ 0.03%, P ≤ 0.03%.
4. Lower-grade sponge iron: TFe ≥ 88%, SO₂ ≤ 10.0%, S ≤ 0.03%, P ≤ 0.03%.
In the field of powder metallurgy, sponge iron with a purity between 97% and 99% is typically used. This high level of purity ensures better performance and quality in the final products.
Packaging options are also customizable. Sponge iron can be packed in 25kg or 50kg bags according to customer preferences.
