What is the implementation standard for sponge iron? Many people may ask about the industry standards for sponge iron. According to Zhengda Sponge Iron Network, there is currently no national production specification for sponge iron. Instead, the industry follows internal standards, and the final technical parameters are ultimately determined based on customer requirements. So, what is the actual standard for sponge iron?
The technical specifications for sponge iron can vary depending on the application and customer needs. Here are some common chemical composition standards:
1. First type: TFe ≥ 95%, SO₂ ≤ 0.65%, S ≤ 0.03%, P ≤ 0.03%.
2. Second type: TFe ≥ 92%, SO₂ ≤ 5.0%, S ≤ 0.03%, P ≤ 0.03%.
3. Third type: TFe ≥ 90%, SO₂ ≤ 7.0%, S ≤ 0.03%, P ≤ 0.03%.
4. Fourth type: 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. The packaging of sponge iron can be customized according to customer preferences, such as 25 kg per bag or 50 kg per bag.
It's important to note that while there are no official national standards, many manufacturers follow these industry-recognized specifications to meet the diverse demands of their clients. If you have specific requirements, it’s always best to consult directly with your supplier to ensure the product meets your exact needs.
