Tempers & Hardness
| Temper | Hardness / Characteristics |
|---|---|
| ANN (Annealed, Soft Temper) | HV ≤185, good formability for deep drawing and bending |
| 1/4H | 190–220 HV |
| 1/2H | 220–260 HV |
| 3/4H | 260–300 HV |
| FH (Full Hard) | ≥300 HV |
Note: Not hardenable by heat treatment. Hardness only increased by cold rolling, magnetic at all tempers.
Common Surface Finishes
| Surface | Description / Applications |
|---|---|
| 2B | Matte silver finish, highest cost-performance, primary grade for industrial stamping |
| BA (Bright Annealed) | Bright reflective surface, for cosmetic parts |
| No.4, HL Hairline, 8K Mirror | For decorative applications |

Material Features
- Ferritic grade without nickel, cost-effective. Better thermal conductivity and lower thermal expansion than austenitic grades like 304
- Good rust resistance in dry atmospheric conditions; poor resistance to chloride and brine, corrosion resistance inferior to 304
- No hardening via quenching. Moderate weldability; prone to intergranular corrosion after welding (430LX with Ti stabilizer for better weld performance)
- Magnetic in all conditions, low work-hardening rate, not suitable for spring shrapnels
Applications
Home appliance panels, range hood parts, oven components, refrigerator back panels, kitchenware, decorative strips, elevator panels, water heater housings, decorative hardware
Material Comparison
| Grade | Key Characteristics |
|---|---|
| 430 | Nickel-free, magnetic, cost competitive, ideal for decoration & home appliances, non-hardenable |
| 420 | Martensitic, heat-treatable for high hardness, suitable for cutting blades |
| 304 | Austenitic, superior corrosion resistance, higher cost, weak magnetism after cold work |
| 301 | Austenitic, high work-hardening, developed for elastic shrapnels |
