High production cost affects the product competitiveness of steel factory, for the production of high-strength steel bars, there is a workable solution to reduce alloy cost to employ Ti replacing N-V for microalloying. The strengthening effect of niobium on steel is mainly fine grain strengthening and diffusion strengthening. Niobium added…
The factors affecting the rolling force are: Absolute reduction In the roll diameter and friction coefficient of the same conditions, the contact area between rolled part and roll becomes large along with increase of absolute amount of press-down, so the rolling force increases. Roll diameter The contact area increases as the roll diameter increases, while the…
In 2016, TISCO successfully developed hand-tear stainless steel with a thickness of only 0.02mm, and in 2020 TISCO created another hand-tear stainless steel with a thickness of 0.015mm, breaking the world’s thinnest record. Ultra-thin high-grade non-oriented silicon steel, thickness of 0.15mm 2023.March, BaoWu New Steel Group’s ultra-thin high-grade non-oriented silicon…
