A dream new material that surpasses the common knowledge of stainless steel! High-strength and highly corrosion-resistant stainless steel!
Stainless steel was traditionally thought to have "good corrosion resistance but insufficient strength." The only way to achieve strength was by using martensitic types, but their corrosion resistance was far from satisfactory. The Perfect Stainless Steel, developed through new steelmaking technology, is a completely new type of stainless steel that simultaneously solves these issues, offering high strength and high corrosion resistance. ● For other features and details, please refer to 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."
