Cold Working
430 can readily be fabricated by cold working. Typical operations include bending, forming, deep drawing and upsetting.
Hardening
430 does not respond to hardening by heat treatment.
| Typical | Minimum | |
| Tensile Strength, MPa | 530 | 450 |
| Proof Strength, 0.2 % , MPa | 360 | 205 |
| Elongation (Percent in Lo=5.65 So) MPa | 25 | 22 |
| Hardness | 160 | - |
Recommended maximum service temperature
(Oxidising Conditions)
Continuous Service 750 oC
Intermittent Service 850 oC
Note: Service in the temperature range 425 -525 oC for over 100 hours will cause the steel to be brittle on cooling to room temperature.
Key: 0 = resistant - corrosion rate less than 100 m/year
Key: 0 = resistant - corrosion rate less than 100 m/year
1 = partly resistant - corrosion rate less than 1000 m/year
2 = non resistant - corrosion rate more than 1000 m/year
