SG-2 and R-2

SG-2 stands for Super Gold 2 and was developed by Takefu Special Steel Co. based in Echizen, Japan. Originally, Takefu Special Steel developed the Super Gold steel but further developed and enhanced their powdered steel metallurgy to develop Super Gold 2. The Super Gold series is based on a modern cutting-edge powdered steel metallurgy that allows for the production of unique materials impossible to get from melting or forming in other ways. SG-2 contains the following amounts of the elements: Carbon: 1.25 – 1.45%, Vanadium: 1.80 – 2.20%, Chromium: 14.00 – 16.00%, Molybdenum: 2.30 – 3.30%. The SG-2 is very similar to ZDP-189 metal and has very high edge retention but has less wear resistance which makes it easier to sharpen.

R2 steel also refers to SG-2 steel. The reason why SG-2 steel is also called R2 is because Echizen blacksmiths initially referred to the SG-2 steel as R2. Over time, due to this confusion, R2 and SG2 are both established steel types but they are the same material.

SG2 Semi-Stainless Steel is forged with traditional methods of craftsmanship blended with modern metallurgy at extremely high temperatures to create a steel composition that is durable enough to be used in industrial machinery and power tools. With a HRC Scale of 64-65, these selection of knives will make and keep its superior edge for an extreme period of time. SG2 Semi-Stainless Steel is a high carbon steel that sits at the pinnacle of maximizing cutting performance and edge retention like no other before it. In addition to the excellent edge retention, the Stainless Steel aspect results in a high level of durability and ease of care. It is perfect for those professionals who have daily high-volume prep work for extended hours.
