Yantai Walsin Stainless produces with new stainless steel combination mill

Primetals has received the final acceptance certificate (FAC) from Yantai Walsin Stainless Steel for a new stainless steel combination mill, enabling Yantai Walsin to produce 420,000 tons per year of stainless steel and nickel alloy products.

The new mill meets the increase in market demand for high-quality stainless steel products in China. For Yantai Walsin, this trend suggests that it converts billets from its existing plant into finished products that achieve tighter tolerances and improved surface quality, which reduces the amount of peeling after pickling and therefore saves costs.
A further benefit for Yantai Walsin was the fact that the bar-in-coil outlet realizes in-line quenching for austenitic and ferritic stainless products, leading to a reduction of subsequent post-processing annealing. Moreover, Primetals Technologies has designed the equipment to accommodate a future addition of an in-line solution for the direct treatment of wire rod products, which also reduces subsequent post-processing annealing. For bar products, the producer now uses a rapid transfer system to slow cooling bins for martensitic grades.
