Unlike regular red rust, it is strong and stable, which will suppress the occurrence of red rust in the future!
"Blackening" is simply a process where the surface of iron is intentionally rusted to prevent further rusting and to protect the interior. The so-called black rust, which is created by the chemical changes in the metal itself, is elegantly black and glossy, enhancing the quality of springs. Unlike regular red rust, it is strong and stable, thus suppressing the occurrence of red rust in the future. However, there is a drawback that if the oil content completely wears off, there is still a tendency to rust slightly. Most of our customers order blackening for iron-based springs, but conversely, not doing so can lead to cost reductions. If you want to make it more rust-resistant, please feel free to ask about "chromate" or "lubrite treatment." Of course, we also accept orders for iron and steel products other than springs, so please do not hesitate to contact us. *For more details, please refer to the PDF materials or feel free to contact us.*
