AISI S1

AISI S1 is a medium carbon tool steel containing tungsten, chromium and vanadium. The beneficial effects of these alloys are well known and, when added to steel of this carbon content in a properly balanced proportion, they impart an excellent combination of moderate hardness and high toughness. S1 is easy to heat treat and can be oil quenched from a wide temperature range. When the steel is oil quenched, it shows little tendency to move or distort. Occasionally a tool steel is required that has a very high toughness value and at the same time a surface of near file hardness. For such applications, S1 can be carburized to produce a wear-resisting surface without loss of the high strength and high toughness of the core. Carburized S1 has solved some intricate tool steel problems when no other type of tool steel would prove satisfactory. Since S1 combines to a good degree both toughness and hardness, it is adapted to wide use. It is excellent for chisels, punches, and pneumatic tools; certain types of hot working dies such as square heading dies for bolts; and for upset dies and dies which are subjected to shock and water cooling.
