Supor is really not rusty. I bought a second-generation healthy iron pot at home when it first came on the market. Its two most prominent characteristics are: refined iron tempering process, more salt and acid resistance. The high-purity refined iron base material is toughened by innovative refined iron, which makes the surface of the iron pan firm and compact, effectively avoids the corrosion of acid and alkali substances to iron-based materials, and ensures that the corrosion of oil, salt, sauce and vinegar to the pot body is fully resisted in the long-term cooking process, thus achieving the effects of firmness and durability. This is also impossible for ordinary stainless steel wok. Uncoated and stainless steel technology, scratch and wear resistance, smooth cooking. High-purity and high-quality refined iron substrate is treated at high temperature by special process, and the surface structure of the pot body is reorganized. The surface of the pot body is uncoated, durable and can be scrubbed at will with steel balls and metal shovels, making the cooking hearty.
