Tempers & Hardness
| Temper | Hardness / Characteristics |
|---|---|
| ANN (Annealed, Soft Temper) | HV ≤210, good ductility for stamping & bending |
| 1/4H | 220–250 HV |
| 1/2H | 250–290 HV |
| 3/4H | 290–330 HV |
| FH (Full Hard) | ≥330 HV |
(as-supplied, unquenched)
Note: Hardenable by quenching & tempering, achievable HRC38～45. Better toughness than 420, slightly better corrosion resistance, 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 | For decorative & structural parts |

Material Features
- Nickel-free martensitic grade, hardenable by heat treatment. Better toughness than 420, less brittle
- Moderate rust resistance, suitable only for dry and mildly corrosive environments, not for chloride or brine service
- Poor weldability, prone to cracking after welding; welded zone loses heat-treatment hardness
- Lower carbon than 420, lower maximum quenched hardness, superior impact toughness
Applications
Valve parts, pump shafts, mechanical structural components, light-duty cutting blades, knife bases, fasteners, tableware, turbine blades, wear-resistant gaskets
Material Comparison
| Grade | Key Characteristics |
|---|---|
| 410 | Martensitic & hardenable, good toughness, medium hardness |
| 420 | Martensitic with higher carbon, higher quenched hardness & sharpness, more brittle |
| 430 | Ferritic, non-hardenable, mainly for home appliance & decoration |
| 304 | Austenitic, good corrosion resistance, non-hardenable |
