Applications 6542 steel is mainly used to manufacture various cutting tools with high cutting speed, heavy load and high working temperature, such as[SCALE STEEL] turning tool, milling cutter, hob, planer tool, broach, drill bit, tap, etc. It can also be used to manufacture cold and hot deformation molds, high temperature springs, high temperature bearings and so on, which require high wear resistance. HTCS-130 is one kind of hot stamping die steel with high thermal conductivity introduced by Rovalma of Spain.
Hot Stamping Forming The automobile high-strength steel plate is heated to the austenite temperature range, quickly moved to the mold to accept the rapid stamping, [SCALE STEEL]under the pressure holding state of the press, through the mold built-in cooling channel, rapid quenching cooling, and finally get the 1500MPa class ultra-high strength stamping parts. Hot Stamping Die Steel The complex working condition of hot stamping requires that the die material has high hardness, thermal conductivity, thermal strength, impact toughness, thermal stability and resistance to cold and hot fatigue.The thermal conductivity is the [SCALE STEEL]key physical property of hot stamping die steel and has a decisive influence on the production efficiency. Usually the mold made of H13 steel with low thermal conductivity can only produce 2~3 stamping parts per minute, while the mold made [SCALE STEEL]of high thermal conductivity mold steel can produce 6~7 stamping parts per minute. Chemical Composition for HTCS-130(%): C 0.31 Mo 3.1 W 1.95 Si 0.17 Cr 0.08 V 0.02 Mn 0.16 P 0.005 S 0.002 Hardness for HTCS-130: HTCS-130 shall be delivered in annealing state, hardness ≤250HB, service hardness range: 34~52HRC. High Thermal Conductivity of HTCS-130 HTCS-130 has an extremely high thermal conductivity of 60W/(m·K) at room temperature, almost twice that of H13 steel.The advantage of [SCALE STEEL]high thermal conductivity is that it can take away heat quickly, which is conducive to the quick quenching of the workpiece. Meanwhile, the fast cooling speed is conducive to reducing the adhesion phenomenon caused by the contact between the mold and the workpiece. Performance Purposes for HTCS-130 Htcs-130 is a kind of high performance hot steel, high thermal conductivity, high toughness, high thermal stability, good wear resistance, good [SCALE STEEL]mechanical performance, excellent polishing performance, often used in the manufacture of plastic injection molding, die casting or casting molding, as well as hot stamping forming molds that need high thermal conductivity. 31CrMoV9 steel is one kind of nitriding structural steel named by European standard; [SCALE STEEL]In GB standard the name is 31Cr3MoV.
