When choosing a stainless steel kitchen sink, you may encounter materials labelled SUS304 and SUS316. While both are widely used in kitchen products and appliances, they differ in their composition, corrosion resistance, and long-term durability. Understanding these differences can help homeowners make a more informed decision when selecting a sink that will withstand years of daily use.
Stainless steel sinks are valued for their strength, hygienic surface, and modern appearance. However, not all stainless steel is the same. The grade of stainless steel used in a sink determines how well it resists rust, staining, and corrosion, especially in environments where moisture, cleaning agents, and food residues are frequently present.
Understanding SUS304 Stainless Steel
SUS304 stainless steel is the most commonly used stainless steel grade in kitchen sinks. It typically contains around 18% chromium and 8% nickel. These elements give the material good resistance to oxidation and corrosion, which is why SUS304 has long been considered a reliable choice for kitchen fixtures.
In everyday household conditions, SUS304 performs well and offers durability suitable for regular kitchen use. It is also widely available and has become a standard material across many kitchen products and appliances. However, prolonged exposure to salt, acidic substances, or harsh cleaning chemicals may gradually affect its resistance to corrosion over time.
Understanding SUS316 Stainless Steel
SUS316 stainless steel is widely regarded as a premium stainless steel grade. In addition to chromium and nickel, it contains a small percentage of molybdenum, an element that significantly enhances the material’s resistance to corrosion and chemical exposure.
The addition of molybdenum allows SUS316 stainless steel to perform exceptionally well in demanding environments. Because of this enhanced resistance, SUS316 is frequently used in marine equipment, medical instruments, and high-performance industrial applications where durability and corrosion protection are critical.
In kitchen environments, SUS316 offers stronger protection against moisture, salt, and cleaning agents that can gradually degrade lower grades of stainless steel. This makes it an excellent choice for homeowners seeking a sink material designed for long-term durability.
Comparing SUS304 and SUS316
Both SUS304 and SUS316 stainless steel are strong and reliable materials suitable for kitchen sinks. However, the presence of molybdenum in SUS316 gives it a clear advantage in terms of corrosion resistance. This means SUS316 is generally better able to withstand harsh conditions, including exposure to salt, chemicals, and high humidity.
While SUS304 remains a common and practical choice, SUS316 provides an added level of durability and protection, making it particularly attractive for premium kitchen fixtures.

Final Thoughts
Choosing the right stainless steel grade plays an important role in the longevity and performance of a kitchen sink. While both SUS304 and SUS316 offer durability and practicality, SUS316 provides enhanced protection against corrosion, moisture, and chemical exposure. For homeowners looking for a premium kitchen fixture built for long-term use, SUS316 stainless steel offers a clear advantage.
