Products Description
Chrome-molybdenum-vanadium steel is characterized by high toughness and good resistance to the wear. Further the steel has good hardenability and good dimensional stability after hardening and tempering. The steel can also be well welded and well polished. The toughness of quality 1.2358 steel reaches higher values than by other steels for cold work (1.2842, 1.2363, 1.2080, 1.2379, 1.2436). An excellent combination of toughness and resistance to the wear enables the usage of quality 1.2358 steel also for different pressing and injection applications during plastics processing.

1.2358 Material Characteristics
- High toughness
- The hardenability to the core is very good
- Suitable for surface hardening (laser, induction, flame)
- Easy to weld
- Can be hardened to 58 Hrc,

1.2358 Tool Steel Applications

Characteristics of 1.2358 tool steel:
1.2358 steel is widly used for making cold work and for molds for plastics. In case of using for cold work we can talk mainly about these applications: cutting and mechanical working (also materials of bigger thicknesses), deep drawing, punching, rolling, production of shear blades, more complicated tools for cold work. In the area of molds for plastics the steel can be used e.g. for molds for large series, molds for plastics with additives, tools for plastics stamping etc.

Preheat T4 steel material uniformly and slowly to 860-880°C.
Increase the forging temperature up to 1050-1120°C.
T4 hss tool steel should be cooled very slowly after forging.
AISI/ASTM T4 Tool Steel Heat Treatment and Properties
Hardening:
Harden T4 high speed tool steel from a temperature of 1260-1290oC followed by oil, air quenching or warm bath at 550oC. Hardness after quenching is 63-66 HRC.
Annealing:
T4 steel should be annealed after hot working. Increase the temperature of T4 high speed steel to 860°C(Max220°C per hour). Hold at the temperature and then cool slowly with the furnace. The annealed hardness achieved should be below HB255.
Tempering:
Tempering temperature: 2x 560-580oC. Hardness after tempering is 64-65 HRC.
