High corrosion resistance, low thermal expansion, strong magnetism! High-performance ferrite-based stainless steel!
We have developed a high-performance ferritic stainless steel "SF-160+α" that achieves corrosion resistance and workability comparable to general-purpose austenitic stainless steel, widely suitable for various applications. SF-160+α offers economic advantages by being free of nickel and molybdenum, along with strong magnetic properties, low thermal expansion, oxidation resistance, and advanced refining technology that reduces harmful impurities and inclusions. By adding trace amounts of copper and niobium, it achieves corrosion resistance close to that of austenitic stainless steel (SUS304 series). SF-160+α not only contributes to the value-added activities of customers using austenitic stainless steel but also facilitates the transition from ordinary steel coated products, providing solutions for a wide range of applications. ● For more features and details, please download the catalog.

Company information
In 1927, our company started as a manufacturing and sales business focused on hardware products such as cotter pins, and in 1957, we began mass production as a pioneer of stainless steel screws. The frontier spirit that lives on at Maruemu Seisakusho has led to the creation of core technologies based on our history and the accumulation of skills, including "product development of new materials, material processing, and fastening technology."
