W-1 Tool Steel Information

W-1 steel is an electric furnace, water hardening carbon tool steel, which provides a hard, wear-resistance case, backed up with a strong, tough core.  These steels are particularly adapted to general-purpose shop tools requiring toughness and resistance to shock and impact.  They are also useful for cutting tools for wood and non-ferrous metals.  This grade responds to simple heat treatments and has a high resistance to decarburization.

W-1 is a water-hardening 1% carbon alloy.  This grade is used where a simple heat treatment is more important than either wear resistance or high dimensional stability during heat-treating. W-1 has many general metalworking applications, but doesn’t provide tool life equal to O-1. Drill Rod in diameters smaller than ½ " usually will harden throughout, but larger cross sections will exhibit a hardened case and a tough core.
