Heat Treatment Technology 410 Material Steel Annealing And Hardening - China

Annealing of 410 material

Annealing temperatures for wrought 410 stainless steel:

1 - Process (subcritical) annealing: Air cool from a temperature of 650-760°C (1200-1400°F).

Maximum softness is achieved by heating to a temperature at the upper end of the range.

Rockwell hardness: 86-92 HRB.

2 - Full annealing: Thoroughly soak at a temperature of 830-885°C (1525-1625°F); furnace cool to 790°C (1455°F), continue cooling to 595°C (1100°F) at a rate of 15-25°C/h (27-45°F/h); air cool to room temperature.

Rockwell hardness: 75-85 HRB.

Isothermal annealing: Heat to 830-885°C (1525-1625°F); hold at 705°C (1300°F) for 6 hours.

Rockwell hardness: 85 HRB.

410 material hardening

Heat to austenitizing temperature 925-1010 °C (1700-1850 °F), usual time in temperature range 30-90 minutes, quenching agent is air or oil (for parts thicker than 6.4 mm (0.25 in), oil quenching should be used; 150-400 °C (300-750 °F) Martensitic quenching bath can be substituted for oil quenching.

Tempering temperature: 205-370 °C (400-700 °F), final tensile strength is 1105-1515 MPa (160-220 ksi), Rockwell hardness is 38-47 HRC.

Tempering temperature: 565-605 °C (1050-1125 °F), final tensile strength is 760-965 MPa (110-140 ksi), Rockwell hardness is 25-31 HRC.

(Not recommended at Tempering in the temperature range of 370-565 °C (700-1050 °F) is not recommended as this will result in reduced and unstable impact properties and poor corrosion and stress corrosion resistance.
