nanoSUS® (NanoSUS) [Special Metal Excel]
It is a material with an ultra-fine grain structure that has been refined to a grain size of less than 1 μm.
Ultrafine grain steel is a material with an ultrafine structure that has crystal grains reduced to less than 1 micrometer. The refinement of crystal grains offers the following advantages: (1) Increased strength By finishing with a fine elongated grain structure through strong processing, it is possible to enhance strength. This enables the reduction of component height and thickness, leading to weight savings. (2) Improved strength-ductility balance By finishing with an equiaxed ultrafine grain structure through heat treatment after strong processing, the strength-ductility balance is improved. This allows for various processing options without sacrificing strength. (3) High fatigue properties Fatigue properties are improved compared to normal grains. This enables longer service life for components. (4) High workability - Reduction of surface roughness Due to the fine structure, surface roughness on the bending areas during metal processing can be reduced. - Stable shear surface during pressing Normal materials with larger crystal grains may experience grain detachment during fine pressing, resulting in an uneven shear surface. With ultrafine grain steel, the contour shape of the fine pressed shear surface can be stabilized.
