202 stainless steel belongs to the austenitic category with chemical composition including chromium, nickel, and manganese. This chemistry provides excellent corrosion resistance, high hardness, good toughness, and superior tensile strength.
- Modulus of elasticity: 210 × 10³ N/mm²
- Density: Approximately 7.80 g/cm³
- Solution annealing: 1000-1050°C followed by water quenching
| Finish Type | Characteristics & Applications |
|---|---|
| NO.1 | Hot-rolled surface, annealed and pickled; used for industrial tanks and chemical devices |
| NO.2D | Cold-rolled, annealed and pickled without skinpassing; suitable for automobile parts, building materials, and piping |
| NO.2B | Better brightness and flatness than NO.2D; comprehensive applications |
| NO.3 | Polished with abrasive belt grit #100-#120; used for building ornaments, electrical appliances, and kitchen utensils |
| NO.4 | Polished with abrasive belt grit #150-#180; applications include bathtubs, kitchen equipment, and food processing |
| HL | Polished with grit #150-320 on NO.4 finish; used for building ornaments, elevators, and frontal plates |
| BA | Cold rolled, bright annealed and skin passed; excellent brightness like mirror; used for electrical appliances and decorative materials |
