2. Equivalent grades


German DIN standard grade: 1.2083

The United States AISI standard grade: 420

Japanese JIS standard grade: SUS420J2

Sweden wins one hundred standard grade: STAVAX.



3. 1.2083 Special Tool Steel Feature


* 1.2083 supply status: annealed, hardness 215 ~ 240HBW.

* Has good corrosion resistance, wear resistance, hardenability and machinability.

* Its low impurity content, due to good corrosion resistance, maintenance costs are relatively low

* High surface accuracy, long-term production can still maintain the original high-precision.



4. Available size(mm)


Plate / Flat Bar Size(mm) Round bar Size(mm)
Thickness Width Length Diameter Length
10-500 155-1200 2000-6000 20-300 3000-6000



5. Usage


1.2083 special tool steel suitable for electric erosion operation, suitable for acidic plastic and require good polishing mold.


Mainly used in the production of PVC molds, wear resistance and filler molds, including hot and hard plastic molds, long-life molds, such as: one-time tableware molds, optical products such as parts, such as cameras and sunglasses, medical containers, etc. 



6. Delivery status


Delivery Status: Steel is delivered in an annealed condition.


Forging: oil quenching die steel has some crack sensitivity, forging heating should not be quickly heated, it is best to preheat 650-750 degrees, forging heating temperature of 1130-1150 degrees, the final forging temperature should be greater than 800-850 Degrees, the maximum ingot forging temperature. Billet forging when the lower limit temperature


Annealing: General annealing using 780-800 degrees, holding 4-6 hours to ≤ 50 degrees / hour, cooled to 550 degrees baked air, isothermal annealing 700-800 degrees 2-4 insulation sales, and then 670-720 degrees insulation, to maintain 2-4 hours, cool to ≤50 degrees / hour cooling to 500 degrees baked air cooling, annealing hardness of 241-197HB



Mechanical properties

● Mechanical properties:

Hardness: annealing ≤ 201HB, indentation diameter 3.9 ~ 4.3mm; quenching, ≥ 50HV


● Heat treatment and microstructure specifications:


Heat treatment specifications: Quenching, 1050 ~ 1100 ℃ oil-cooled
Tempering, 200 ~ 300 ℃ fast cooling.
Metallography: The organizational characteristics of martensite type.
