Steel material



SG2 is one of the steel materials used in kitchen knives and is especially known for its use in high-quality knives. Below are some of the characteristics of SG2 steel.

  1. Ultra-hardness: SG2 steel is a very hard steel. Hardness is expressed in terms of Rockwell hardness (HRC), which is typically above 60. This high hardness ensures durability and long-lasting sharpness of the blade.
  2. Excellent sharpness: SG2 steel has a fine particulate steel structure that forms sharp edges on the cutting edge. As a result, SG2 steel knives are extremely sharp and can cut through food smoothly.
  3. Durability and strength: SG2 steel has high hardness and strength, as well as high abrasion resistance, which means that the cutting edge will not deteriorate over long periods of use.
  4. High rust resistance: SG2 steel contains alloying elements such as chromium and molybdenum, which give it excellent rust resistance. As a result, it is relatively resistant to moisture and oxidation, and if knives are properly maintained, they are said to be rust-resistant. However, it is important to note that it rusts easily due to its high carbon content among stainless steels.
  5. Care precautions: Because of its high hardness, SG2 steel tends to rust more easily than other steels. It is important to properly clean and dry knives after use to prevent rust from forming.

SG2 steel is a steel material characterized by high hardness, sharpness, and durability. Knives made of this steel are highly regarded by professional chefs and knife enthusiasts. However, due to its high carbon content, proper maintenance is required and care should be taken.
