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.
