AISI 1214
Carbon is the primary alloying element present in the carbon steels. They contain 0.4% silicon and 1.2% manganese. Small quantities of molybdenum, chromium, nickel, aluminium, and copper are also present in these steels. AISI 12L14 carbon steel is known as the fastest machining bar product.
