NSR (Nano Scratch Resistant Surface) stainless steel is an advanced innovation in titanium coating technology. This process enhances the surface hardness of stainless steel using nano-technology combined with PVD (Physical Vapor Deposition) coating.

Typically, standard stainless steel has a surface hardness of around 200 HV. When coated with PVD, the hardness increases to approximately 300 HV. With the additional NSR treatment, the hardness can reach up to 500 HV—an increase of nearly 70% from the original surface. As a result, this finish offers excellent resistance to scratches, making it ideal for applications requiring high durability and long-lasting surface quality.
