What is the difference between sus304 stainless steel and food grade 304?

Stainless steel is a common material widely used in various industries. In stainless steel, SUS304 stainless steel and food grade 304 are two very common types. Although they look very similar, there are actually some differences and differences in their applications. This article will provide a detailed introduction to the differences between SUS304 stainless steel and food grade 304, helping readers better understand and choose materials that are suitable for their needs.

Firstly, SUS304 stainless steel and food grade 304 are both austenitic stainless steels. Austenitic stainless steel has excellent corrosion resistance and oxidation resistance, which enables them to perform excellently in various environments. Both types of stainless steel provide reliable protection, whether exposed to harsh outdoor environments or in internal environments that require contact with food and liquids.

However, differences also exist. Firstly, SUS304 stainless steel is a versatile stainless steel material with a wide range of applications. It is often used to make various models of stainless steel pots, stainless steel sinks, stainless steel kitchenware, etc. Due to its excellent corrosion resistance and mechanical properties, SUS304 stainless steel can be used in various atmospheric and chemically corrosive environments.

Food grade 304 stainless steel is a more professional material suitable for places in direct contact with food. It is a stainless steel material that has undergone special treatment to remove impurities and harmful elements. This makes food grade 304 stainless steel very suitable for making food processing equipment, stainless steel kitchenware, and food storage containers. It does not produce any harmful substances to food, nor does it alter the taste or odor of food.

In addition, food grade 304 stainless steel also has different surface treatments. It is usually polished or sandblasted to ensure a smooth, flat surface and easy cleaning. This is to meet the strict hygiene requirements of the food industry and prevent the growth of impurities and bacteria.

In summary, the differences between SUS304 stainless steel and food grade 304 are mainly reflected in their usage and surface treatment. SUS304 stainless steel is widely used in various industrial fields, while food grade 304 stainless steel is specifically designed for places in contact with food. Food grade 304 stainless steel has higher hygiene standards and is suitable for equipment and containers used in the manufacturing and processing of food. Regardless of which material to choose, it is necessary to make judgments based on specific needs to ensure that the materials used meet the requirements.

I hope that through the introduction of this article, readers can better understand the difference between SUS304 stainless steel and food grade 304, and make the correct choice in practical applications. If you have further questions or needs, please feel free to consult professionals for more accurate information and advice. Choosing appropriate stainless steel materials will bring more convenience and safety to our lives and work.
