When shopping for cookware, knives or kitchen tools, you may notice labels like SS 201, SS 430 or 18/8 stainless steel. These grades are not just technical terms, they represent different types of stainless steel designed for different purposes. Each grade varies in hardness, corrosion resistance, polish quality, magnetic properties and cost, depending on the combination of elements used, such as chromium, nickel, carbon, molybdenum and vanadium.
That’s why stainless steel is divided into grades, not to determine which is “best”, but to ensure the right material is used for the right application. When selected correctly, even economical grades can perform exceptionally well, while premium grades are used where higher durability or performance matters most. In the end, the real difference is not just the label, but how well the material is used in the product.
Stainless steel is mainly made from iron and chromium but different grades contain varying amounts of elements such as nickel, carbon, molybdenum and vanadium. Because of this, different grades are suitable for different kitchen applications. These combinations affect factors like:

SS 201 is commonly used for kitchen accessories and non-cooking tools such as strainers, skimmers and utensil holders. This grade offers moderate hardness and corrosion resistance while remaining easy to shape and manufacture, making it a practical and cost-effective option for everyday kitchen accessories.
Although SS 201 performs well for general kitchen use, it is more suitable for tools that are not constantly exposed to direct cooking heat or long-term food storage. When used for the correct application, it remains a reliable and affordable material choice.
SS 430 is widely used for cooking utensils, kitchen gadgets and cutlery because of its strength, durability and corrosion resistance. It is also magnetic and can achieve a smooth mirror-polished finish, giving kitchen tools a clean and premium appearance.
This grade is commonly chosen for products that come into regular food contact, making it a dependable material for daily cooking and serving needs. Its balance between durability, appearance and practicality makes SS 430 one of the most popular food-grade stainless steel options used in kitchenware today.
SS 420 is one of the most commonly used stainless steel grades for kitchen knives, ranging from entry-level knives to professional kitchen tools. It offers a balanced combination of durability, chip resistance and ease of maintenance, making it suitable for daily food preparation.
This grade is designed to provide practical cutting performance while remaining relatively easy to sharpen and maintain over time. Because of its reliability and everyday practicality, SS 420 continues to be widely used in many household and professional kitchen knives.
SS 420 MoV is an upgraded version of SS 420, enhanced with additional elements such as Molybdenum and Vanadium. These improvements help increase edge retention, corrosion resistance and overall cutting performance, allowing the knife to stay sharper for a longer period of time.
This premium knife steel is commonly used in higher-performance kitchen knives where smoother cutting, better durability and improved sharpness are important. It is especially suitable for users who cook frequently and prefer knives with enhanced performance and longer-lasting sharpness.
SS 304, also known as 18/8 stainless steel, is one of the most widely recognized premium stainless steel grades used in cookware, food containers and hydration bottles. It offers excellent corrosion resistance, especially against acidic foods and liquids, while maintaining a durable and clean finish suitable for long-term food contact.
Unlike some other grades, SS 304 is generally non-magnetic and is highly valued for its food safety, durability and premium appearance. Because of these qualities, it is commonly used in products that require dependable long-term performance and frequent food contact.
Different stainless steel grades are designed for different kitchen applications, which is why there is no single “best” stainless steel for every product. A kitchen knife, a cooking utensil and a food container all require different material properties to perform effectively in daily use. When the correct grade is selected for the right purpose, the product is able to deliver better durability, functionality and overall user experience.
At Fukuro, every product is carefully designed with practicality and everyday performance in mind. From strainers and cooking utensils to knives and food-contact products, different stainless steel grades are thoughtfully selected based on how the product is meant to be used. This allows Fukuro to provide kitchenware that balances quality, reliability and value for modern households.
