CarTech S2 Steel

CarTech S2 Steel

Steel name: S2
Diagram No.: 2301
UNS designation: T41902
AISI/SAE designation: S2
Chemical composition in weight %: 0.50% C, 1.00% Si, 0.40% Mn, 0.50% Mo
Steel group: Tool steels
Properties: CarTech S2 tool steel is a water hardening steel possessing extreme toughness. Even at Rockwell C 59/60, it will bend before it breaks. When hardened in medium and large size sections, CarTech S2 tool steel develops a hard case and a tough core. The combination of extreme toughness, hardness and wear resistance makes CarTech S2 tool steel suitable for use in many applications where other tool steels will not perform.
Applications: Punches, knock-out pins, clutch pins, indexing pins, trimming dies, crimping dies, swaging dies, wrenches, fingers, shear blades, heavy-duty forming tools, heavy-duty coining dies, special knurls, stamps, jaws.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: During hardening, suitable protection should be provided to prevent excessive scaling and decarburization. First, heat the salt bath or furnace to 1550°F (843°C). Without preheating, place the tool right in the hot furnace near the thermocouple and let it heat naturally until it uniformly matches the color of the thermocouple. Soak five minutes per inch of thickness, then quench in brine.
Tempering: Solar tool steel should be tempered to achieve the hardness shown by the hyperlink titled "Effect of Tempering Temperature on Hardness." Most tools should be tempered at 300°F (149°C) to produce a hardness of Rockwell C 59/60. Shanks of pneumatic chisels should be tempered at 900°F (482°C). When Solar tool steel is oil quenched from 1600°F (871°C), temper at 275/300°F (135/149°C) to relieve hardening strains.
