VG-1 (steel)

VG-1 (also known as V Gold 1 steel) is a high Carbon (C) Molybdenum (Mo) stainless steel manufactured by Takefu Special Steel Co.,Ltd.[1] It is not the same steel as VG-10.

VG-1 has a Carbon (C) content between 0.95-1.05 %, Chromium (Cr) content between 13.0-15.0 %, Molybdenum (Mo) content between 0.2-0.4 % and contains less than 0.25 % of Nickel (Ni).[2] During forging, Mo and Cr form hard double carbide bonds, which help improve the abrasion and corrosion resistance of the steel.[3] It is usually heat treated to reach hardness of 58-61[4]

Knife retailer Cold Steel markets a variety of knives that use VG-1.[5] Cold Steel claims that VG-1 has better sharpness, edge retention, point strength, shock and strength characteristics than 440C, VG-10, or ATS 34 stainless steels, though any of those alloys may be better than VG-1 in individual categories.[6] There have been reports that VG-1 might be more chipping prone than other comparable stainless steels, but these reports have been disputed.[7]

VG-1 is also used in hairdresser's scissors, kitchen knives and blades for food-processing machines.[8]
