Chemical Composition (SX105V)
1. SX105V is a new type of cold work tool steel, also known as flame quenching cold work tool steel. It belongs to the series of high carbon low alloy cold work tool steel. The typical elements of SX105V are Cr, Si, Mn, etc. A small amount of strengthening elements, like Mo and V are also included.
2. The range of quenching temperature of SX105V is very wide, but the thermal sensitivity is very low. Flame quenching is characterized by simple operation, low costs and saving resource.
3. The hardenability of SX105V is good. It can be hardened by cooling in air. Its hardness can reach 62 ~ 64HRC. The quenching deformation is very small.
4. SX105V has high strength, good toughness and relatively high wear resistance after heat treatment. It is suitable for making various types of manual mechanical wrench, screwdrivers, pneumatic chisel, heavy duty punch, scissors, heavy vibration cutting and so on. It is strongly recommended for manufacturing cold work tool steels requiring large dimension, thick section and small deformation during quenching.
SX105V is equipped with very good comprehensive mechanical properties. It can be used in all kinds of cold work tool steels, such as sheet punching die, sizing die, trimming die, cold extrusion die, etc. SX105V can be quenched by flame. SX105V can take place of T10A, O2 and D2 to manufacture cold work dies requiring high toughness. The service life of the dies made of SX105V is significantly improved. If the cold work dies demand much higher toughness, DC53, D2, S7 and A2 are for the customer’s selections.
