AN PHAT SUS 430 STAINLESS STEEL COILS
Ferritic stainless steel - Good corrosion resistance - Widely used in household & industrial applications
SUS 430 stainless steel (Grade 430) is a ferritic steel line renowned for its perfect balance of corrosion resistance, formability, and cost-effectiveness. At An Phat Stainless Steel, we provide high-quality 430 stainless steel coils, serving diverse needs from household appliance manufacturing to industrial technical components.
What is SUS 430 stainless steel?
Grade 430 is a stainless steel primarily composed of Chromium and Iron. Its most distinctive feature is its magnetic response (attracted to magnets), making it widely used in induction cooktop products.
Beyond the standard grade, other variants include:
- 430F: Bar form, frequently used in automatic screw machines.
- 434: A version containing Molybdenum for enhanced corrosion resistance.
Technical specifications and properties
Chemical formula: Fe, <0.12% C, 16-18% Cr, <0.75% Ni, <1.0% Mn, <1.0% Si, <0.040% P, <0.030% S.
Heat resistance
Grade 430 demonstrates impressive thermal durability:
- Intermittent service: Resists oxidation up to 870°C (1598°F).
- Continuous service: Operates stably at 815°C (1499°F).
- It can withstand prolonged heating in the 400°C to 600°C range without significant deformation.
Fabrication and welding
- Welding: Strong welds can be achieved with pre-heating at 150-200°C.
- Machining: Compared to Austenitic steels, Grade 430 is easier to machine and draw, making it highly convenient for mass production.
Superior features of SUS 430 at An Phat
- Corrosion resistance: Its resistance to pitting and crevice corrosion is comparable to grades 304 or 403, especially when the surface is polished.
- Excellent formability: Easily bent or stamped into complex components.
- Cost optimization: An ideal budget-friendly material solution for applications that do not require extreme resistance to saline environments.
Common applications of 430 stainless steel coils
Due to its magnetic and heat-resistant properties, 430 stainless steel coils are considered a "premium material" in:
- Kitchen appliances: Manufacturing induction-compatible cookware and dishwasher components.
- Refrigeration: Refrigerator panels and appliance housings.
- Mechanical & construction: Production of fasteners, support elements, chimney liners, and stove parts.
- Automotive industry: Car trims and wiring systems.
