SG2 (Super Gold 2, also known as SPG2 and R2) is an advanced powdered stainless steel that excels in edge retention and corrosion resistance, making it ideal for high-performance kitchen knives. Its balanced composition of carbon, chromium, tungsten, molybdenum, and vanadium is produced through powder metallurgy, creating a uniform microstructure that surpasses traditional forged steels in sharpness, wear resistance, and corrosion protection.
In the culinary world, SPG2 has earned a reputation among professional chefs and serious home cooks for its ability to maintain sharpness during extended periods of use. While it may require more effort to sharpen due to its high hardness (which can reach up to 64 HRC), the extended edge retention more than compensates for this minor inconvenience. The steel's balanced properties make it particularly well-suited for precision cutting tasks where both sharpness and durability are essential.
