1.Specification of carbon steel 1020
The specification can be customised!
2.Chemical compositon of carbon steel 1020
carbon steel 1020
3.Delivery condition of carbon steel 1020
Hardening and Tempering
carbon steel 1020
Subcritical annealing: 650~700
Isothermal annealing: 820~860
4.Heat treatment of carbon steel 1020
1.Quench:1000-1040`C via 600`C and 850`C, preheating oil or wind cooling
2.Temper temperature should be higher than working temperature in order to stabilize the working size of mold
3.Heat up to 650°C of average temperature in order to eliminate the machined stress, 500 °c air cooling after electric cooker cooling
4.Tempering, 800-850 °c ,slow cooling after diathermia
5. Melting Process of SKD61 steel rod
1.EAF: Electric Furnace+LF+VD(Optional)
5.Characteristic of carbon steel 1020
Nice machanical porpertys and worse hardenability,so, it is used for machine parts
6.Application of carbon steel 1020
(1)Can be made into mould template, mortise pin, column
