AISI H11 tool steel is a 5% chromium hot-work tool steel. Gnee steel supplies good quality H11 steel, and equivalents 1.2343/X37CrMoV5-1, SKD6, BH11 steel.AISI H11 Steel Round Bar Sheet Plate, DIN 1.2343, JIS SKD6 H11 steel also is called DIN 1.2343 and JIS SKD6 steel. 1.2343 steel is the air-cooling type hot work mold steel. It is one of the three most commonly used of hot work mold steel in the European die-casting industry. The carbide is small and distributed uniformly in steel.
