  • OverviewUsesDescriptionClimateIntroductionTreatmentCharacteristicsS7 Shock-Resisting Tool Steel is an air or oil hardening tool steel that is characterized by very high impact toughness. The combination of strength and high toughness makes it a candidate for a wide variety of tooling applications. It can be used successfully for both cold and hot work applications. Also suitable for hot work tools where the operating temperature does not exceed 1000°F (538°C). For plastic injection molds, S7 tool steel is available as a remelted, mold-quality product. The remelting process miSpeedy Metals Information for S7 Tool SteelS7 is a shock resisting tool steel with excellent toughness and high strength, along with medium wear resistance. It has maximum shock resistance and high compression strength, which gives it good deformation resistance in use, while retaining good toughness. S7 is easy to machine in the annealed condition and can be readily heat treated.sp.info S7, D2, A2:Difference in tool steel properties PauloFeb 20, 2018 · S7 tool steel is a versatile formulation suitable for both cold and hot work service. It has a relatively low carbon concentration compared to D2 and A2 steels (0.45 ā€“ 0.55%) and significantly less chromium (3.00 ā€“ 3.50%). It features excellent impact and shock resistance and decent resistance to softening at high temperatures.sp.info Is S7 tool steel machineable by a HSM? - Practical MachinistDec 11, 2008 · S7 is a very nice machining steel, and easy to heat treat. (with a furnace) The only caveat is as with any airhardening steel, you need to run the cutters sharp, slower sfm, and don't dwell or let it rub, keep it cutting. If you locally overheat the material, it can spot harden & ruin your tool. But less of a problem with S7 than with some others.sp.info S7 Tool Steel-Pros & Cons? BladeForums

This steel is relatively easy to machine, can be hardened to Rockwell 54-59, which is certainly hard enough for a mold. It is easy to polish to a high lustre, is sp.info A7 Steel A7 Technical Data - Tool Steel High Speed SteelA7 Wear-Resistant Tool Steel. A7 Wear-Resistant Tool Steel is a chromium-modified A7 type air-hardening tool steel that exhibits exceptional wear resistance. The high carbon and vanadium contents result in numerous, hard vanadium carbide particles in the steel. These carbides exhibit a hardness that is equivalent to approximately 80 to 85 Rockwell C. Resists wear from sliding contact with other steels

      Tool steels are usually supplied in the annealed condition, around 200/250 Brinell (about 20 HRC), to facilitate machining. In this condition, most of the alloy content exists as alloy carbides, dispersed throughout a soft matrix. These steels must be heat treated to develop their characteristic properties. The heat treating process alters the alloy distribution and transforms the soft matrix into a hard matrix sp.info Difference Between Carbide and High Speed Steel Compare Jun 14, 2018 · The key difference between carbide and high speed steel is that the carbide is extremely hard and abrasion resistant and therfore, the tools made from carbide last longer than that made from high speed steel.However, the hardness and abrasion resistance of high speed steel is superior to that of common carbon steel and tool steel..

      • Tooling FailuresTool Steel TestingBlanking Test ResultsFurther TestingA proprietary, third-generation powder metallurgy (P/M) tool steel, developed to be both strong and ductile, also was selected for testing, using identical test conditions and parameters, to compare its performance to AISI D2 and AISI S7 tool steels. The P/M manufacturing process produces small, evenly distributed carbides that are distributed throughout the microstructure. This allows a greater number of alloying elements to be added, and more carbides, which increases wear resistance without decreaCryogenic Treatment and Its Effect on Tool SteelFeb 21, 2014 · Cryogenic Treatment and Its Effect on Tool Steel.
