No.1 Finish: Rough, Rugged, and Reliable: Mastering the Heavy-Duty Applications of Hot-Rolled No.1 Plates

Among the various stainless steel surface finishes, the No.1 finish stands out for its raw industrial strength and exceptional durability. Primarily utilized in heavy-duty sectors, hot-rolled No.1 plates represent the ultimate fusion of structural integrity and functional performance. Wuxi Xinshanhu Steel Co., Ltd. (XSHSteel) provides a comprehensive range of high-quality No.1 finish plates to our global partners.

What is No.1 Finish?

The No.1 finish refers to a surface that has been hot-rolled, annealed, and descaled (pickled). It features a dull, non-reflective, and slightly rough silver-white appearance. This finish is not designed for aesthetic appeal but rather for maximum performance in rigorous industrial environments where durability is paramount.

Process Core: Hot Rolling and Heat Treatment

The production of No.1 plates involves rolling steel slabs at high temperatures. Subsequent annealing relieves internal stresses and restores ductility, while the pickling process removes the oxide scale formed during hot rolling. This ensuring a uniform, corrosion-resistant surface. This methodology allows the plates to maintain superior strength even in significant thicknesses.
