How is the hardness of stainless steel compared to ordinary steel

Typically, stainless steel is usually harder than ordinary carbon steel. Stainless steel is an alloy steel that usually contains chromium, nickel, and other elements, which gives stainless steel better corrosion resistance and mechanical properties. Due to the higher content of alloying elements in stainless steel, they are generally harder than regular carbon steel.

The hardness of stainless steel can vary depending on its specific alloy composition and heat treatment process, so the hardness of different grades and types of stainless steel will also vary. Generally speaking, the hardness of stainless steel gives it advantages in wear resistance and corrosion resistance, so it is widely used in situations where durability and corrosion resistance are required, such as kitchen utensils, building materials, chemical equipment, and other fields.
