304 Stainless Steel Shell



Why do high-end home appliances, especially those related to drinking water, use 304 stainless steel for their shells?

Core Reason: Absolute Material Safety (Health Assurance)
Water-related appliances directly impact the safety of users' drinking water. As the part that comes into prolonged contact with water or water vapor, the shell must not become a source of secondary pollution.

No Leaching Risk:

  • Vs. Plastic: Even food-grade plastic, when used over long periods in high-temperature and high-humidity environments, may leach trace substances (such as plasticizers, unpolymerized monomers, etc.). Stainless steel, however, is an extremely stable alloy, with its components securely locked in the lattice structure, never leaching any harmful substances into the water under any circumstances, ensuring pure water quality at all times.
Naturally BPA-Free:
  • Stainless steel itself does not contain or require the addition of any endocrine-disrupting substances like bisphenol A (BPA). For families particularly concerned about the health of infants and young children, this provides great peace of mind.

Outstanding Physical and Chemical Properties (Durable and Reliable)
Strong Corrosion Resistance:

  • 304 stainless steel contains 18% chromium and 8% nickel (hence the name "18/8 stainless steel"). Chromium forms a very thin and dense passivation layer on the surface, giving it excellent resistance to rust and corrosion in air or water. It is also resistant to common cleaning agents, ensuring long-lasting durability.
High Strength and Wear Resistance:
  • Compared to plastic and glass, stainless steel has higher mechanical strength, making it resistant to bumps, scratches, and unlikely to deform or break. This means the product will maintain its aesthetic appeal throughout its entire lifecycle and will not easily show signs of wear and tear, offering exceptional durability.
Excellent Antibacterial Properties:
  • This is a major advantage for water-related appliances. Copper also has antibacterial properties but is prone to rust and is expensive. While stainless steel does not kill bacteria as quickly as copper, its extremely smooth, seamless surface makes it very difficult for bacteria to adhere and grow. Research shows that bacteria survive on stainless steel surfaces for much less time than on porous plastic surfaces. This is critical for maintaining hygiene on the appliance's surface.

Top-tier User Experience and Sensory Value (High-end Experience)
Easy to Clean and Maintain:

  • The smooth, non-porous surface does not absorb pigments, scale, or stains, making it easy to clean with just a wipe. Unlike plastic, it won’t yellow or retain odors over time.
Thermal Stability:
  • For instant water purifiers or kettles, the outer shell will come into contact with heat during operation. Stainless steel better withstands temperature changes without deforming or releasing odors like plastic does.
High-end Feel and Aesthetic:
  • The metallic cold touch, solid feel, and gloss instantly enhance the product's premium feel and value perception. It conveys a visual language of "strength, reliability, professionalism," perfectly aligning with the brand positioning of high-end appliances. Its simple, stark industrial style also easily integrates into various modern home decor styles.

Environmental Responsibility and Sustainability (Brand Responsibility)
100% Recyclable:

  • Stainless steel is a highly valuable recyclable material that can be reused indefinitely without degrading in quality. Using a stainless steel shell demonstrates the brand's commitment to environmental responsibility, resonating with high-end consumers' growing environmental consciousness.
Long Life Cycle:
  • Due to its exceptional durability, the product’s lifespan is greatly extended, fundamentally reducing electronic waste caused by product obsolescence, aligning with sustainable development goals.
