What Is 430 Stainless Steel?
In the global application field of stainless steel, 430 stainless steel has become the ideal choice for construction, home appliances and industrial manufacturing due to its excellent cost performance and reliable performance. As a supplier specializing in stainless steel exports, we provide global customers with 430 stainless steel coil, strip and customized processing services that meet international standards.
The Chemical Composition Of 430 Stainless Steel
430 stainless steel belongs to ferritic stainless steel, and its core components are:
- 16-18% chromium: Forms a dense oxide film, providing basic anti-rust ability
- ≤0.12% carbon: Low-carbon design to ensure formability
- ≤1% manganese/silicon: Optimize mechanical processing performance
- 0.03% sulfur and phosphorus control: Complies with RoHS environmental protection standards
The Core Characteristics Of 430 Stainless Steel
Corrosion resistance
- It is resistant to atmospheric environment, fresh water and mild acidic and alkaline media
- Passed the 72-hour salt spray test (ASTM B117 standard)
Thermal stability
- Continuous operating temperature range: -20℃ to 850℃
- The oxidation resistance is three times better than that of ordinary carbon stee
Processing advantage
- Elongation ≥22% (ASTM A240)
- Brinell hardness HB≤183, suitable for cold working such as stamping and bending
Diversity of surface treatment
- Supports surface processing such as 2B/BA/No.4/HL, and can be further treated with PVD color plating
Typical Application Scenarios Of 430 Stainless Steel
Architectural decoration field
- Elevator car/interior decorative strips (presenting high-end texture after HL brushing treatment)
- Roof corrugated sheet (coated enhanced version available for coastal areas)
Household appliance manufacturing
- Microwave oven casing/gas stove panel (certified by FDA Food grade)
- Washing machine inner drum (replacing part of 304 application to reduce cost)
Industrial components
- Automotive exhaust system (Alternative to 409L)
- Lining of chemical storage tanks (used in conjunction with anti-corrosion coatings)
The field of daily necessities
- Tableware/kitchenware (conforming to the EU EN 1811 nickel release standard)
- Supermarket shelves/logistics and warehousing equipment
