Hot rolled F1 sheets: strength, precision and reliability for structural and industrial applications

Robust, dependable, and versatile—F1 finish hot-rolled stainless steel sheets are among the most effective solutions for industrial applications requiring mechanical strength, long-term durability, and surfaces suited for further processing. In this segment, Oiki Acciai Inossidabili Spa stands as a European reference point, offering immediate availability, standardised formats and advanced value-added services.F1 Sheets are produced through hot rolling, followed by annealing and pickling. The result is a dull grey surface with a rough, industrial appearance, particularly suitable for structural works, pressure vessels, plant engineering, and heavy-duty fabrication. Technical specifications:1) Standard EU formats: from 1,000 x 2,000 mm to 2,000 x 6,000 mm;2) Thickness range: from 2.0 mm to 80.0 mm;3) Available grades:- Austenitic: 304L, 316L, 316TI, 321, 309S, 310S- Ferritic: 430, 1.4003 (3Cr12)- Duplex: S 32205This wide selection allows for tailored responses to sectors with high technical complexity, ensuring reliable performance in corrosive environments, high-temperature exposure, or demanding mechanical conditions. Certified finishing services on requestOn demand, Oiki can supply Sheets with controlled surface roughness, equal to or lower than Ra ≤ 0.6 µm—ideal for applications where interaction with fluids or metal-to-metal contact demands the highest surface precision.Each sheet is delivered with official roughness certification, guaranteeing full compliance with specified parameters.Thanks to a centralised 35,000 m² warehouse, Oiki ensures fast order fulfilment and a streamlined, efficient logistics process, even for large volumes. Decades of experience and an agile yet structured organisation make Oiki a reliable partner throughout the entire supply chain.Choosing Oiki means relying on certified F1 stainless steel—custom-processed and ready when needed.
