SS 2310 Cold work tool steel - mechanical properties

Cold work die steel, steel hardenability, quenching tempering hardness, wear resistance, strength are higher than the Cr12.Shape is complex, the working conditions under the heavy cold die and tools, such as punching die, blanking die, piping mold, steel sheet deep drawing tools, circular saw, standard and gauge, thread rolling dies, etc.


 Heat treatment specification
Heat treatment specification: 1. The quenching, 950 ~ 1000 ℃ oil cooling;2. The quenching 1020 ℃, 200 ℃ tempering 2 h.
Microstructure: fine granular pearlite + carbide.
Delivery status: steel in annealing state delivery.
Cold extrusion touch into billet softening specification
Make ⽤ ⽣ iron protection heating, the temperature is 760 ~ 780 ° C, time 10 h, furnace cooling, l96HBW hardness, can be smooth realization of cold extrusion forming
Ordinary isothermal spheroidizing annealing specification
850 ~ 870 ℃ by 3 ~ 4 h, along with the furnace cooled to 740 ~ 760 ℃ isothermal x 4 ~ 5 h, from empty cold hardness 241 HBW, or less eutectic carbide grade 3 or less
Best isothermal temperature 740 ~ 76 ° C, o time 4 ~ 5 h or more
The spheroidizing annealing specification
° C (860 + 1 u) x 2 ~ 4 h, at 30 ° C/h speed furnace cold, (740 +) 10 ° C x4-6 h, with the slow cooling furnace to 500 ~ 600 ° C, from air cooling. Hardness of 207 ~ 255 HBW.
Cryogenic treatment
Crl2MoV steel after cryogenic treatment, cryogenic treatment can make the quenching martensite highly dispersion of ultrafine carbides precipitate, then after 200 ℃ low temperature tempering, these ultrafine carbides can be transformed into carbide.Without the cryogenic treatment of martensite, after low temperature tempering, only has a small number of carbide precipitation in some local areas.Crl2MoV by low temperature chemical heat treatment method, in keeping the Crl2MoV steel on the basis of the high hardness and high wear resistance of ion nitriding, nitrogen gas carbon altogether permeability, salt bath sulphur cyanogen altogether permeability kind of commonly used low temperature chemical heat treatment of carbonitriding layer adhesion force.Three kinds of low temperature chemical heat treatment of infiltration layer have a significant impact resistant adhesive effect, especially in salt bath sulphur cyanogen permeability best.Crl2MoV steel stainless steel household utensils after tensile modulus were treated with nitrogen gas carbon altogether permeability, the service life of more than 30000 pieces, the conventional quenching and tempering treatment of the similar die life increased by more than 10 times.
