C15 stainless steel is not inherently harder than V4A stainless steel. The hardness of stainless steel is determined by its composition and heat treatment, rather than the specific grade. Both C15 and V4A stainless steel can be heat treated to achieve different levels of hardness. Therefore, the hardness of each grade can vary depending on the specific heat treatment applied. **

All stainless steels are considered to be stainless because they contain a minimum of 10.5% chromium, which creates a protective layer of chromium oxide on the surface of the steel. This layer prevents corrosion and staining, giving stainless steel its characteristic resistance to rust and corrosion. Additionally, stainless steels may also contain other alloying elements such as nickel, molybdenum, or titanium, which further enhance their resistance to corrosion and staining. Therefore, all stainless steels share the common characteristic of being resistant to rust and corrosion, making them suitable for a wide range of applications. **

Yes, stainless steel jewelry is made of real stainless steel. Stainless steel is a durable and corrosion-resistant metal that is commonly used in jewelry making.
