The S1 Tool Steel is oil-hardening, non-deforming tool steel which can be hardened at relatively low temperatures. Tools and dies made from S1 Bars will have good wearing qualities since the tungsten and higher chromium content gives improved wear resistance over the straight manganese grades. The tungsten content of this tool steel grade confers fatigue resistance, the chromium content gives a depth of hardness and resistance to abrasion. S1 tool steel is shock-resisting steel. It performs excellently in cold and hot work shock applications.


S1 Tool Steel Bars offers outstanding service in both hot and cold working applications. S1 tool steel bars are resistant to heat checking. S1 Die Steel Bars are suitable for hot work applications where high fatigue strength in combination with medium-hot hardness is desirable.


S1 steel bars are mainly used for Mandrel drawing steel tubes. Medium temperature applications include forging, forming, and die punching. In addition, this stainless steel tool is widely used for Heavy-duty blanking and forming dies punches, chisels, shear blades, slitter knives, cold striking dies, cold extrusion tools, coining dies, master hobs.


The tool steel contains low carbon that provides great toughness. Its blend of alloying components gives the carbide formation necessary for abrasion resistance, the hardenability necessary for shock tools, and improved hot work characteristics. Additionally, these S1 Tool Steel Bar is used for carburizing during pack hardening.
