Sleipner is a tool steel from Bohler-Uddeholm, created as a modification of D2 steel. Sleipner steel has good wear resistance and edge retention comparable to D2 steel. At the same time, however, it is more resistant to chipping and has higher toughness (compared to D2). It can reach a hardness of 60-64 HRC. Sleipner is not stainless steel, but its corrosion resistance is higher than that of classic carbon steels.

Steel composition: 0,9% carbon, 7,8% chromium, 2,5% molybdenum, 0,9% silicon, 0,5% vanadium, 0,5% manganese.
