‌304 stainless steel food grade

304 food grade stainless steel is a stainless steel material that meets food safety standards and is widely used in food manufacturing and processing industries. ‌

The main components of 304 food grade stainless steel include 18% chromium and 8% nickel. This combination of ingredients gives it good corrosion resistance and processing performance. Compared with ordinary 304 stainless steel, food grade 304 stainless steel has more stringent requirements in terms of safety, hygiene performance and surface treatment.

Food grade 304 stainless steel must meet food safety standards, which means it must pass rigorous testing and certification to ensure its safety and reliability. In contrast, although ordinary 304 stainless steel also has good corrosion resistance, it does not necessarily meet food safety standards.

In food contact applications, food-grade stainless steel is often subjected to special surface treatment to improve its corrosion resistance and hygienic properties. This treatment allows food-grade stainless steel to maintain its appearance while more effectively preventing bacterial growth and food contamination.

Food-grade 304 stainless steel requires special surface treatment to ensure that its surface is smooth, not prone to the growth of bacteria and dirt, and easy to clean and disinfect. This treatment is to ensure the hygiene and safety of the product, especially in the food manufacturing and processing industries.

The difference between 304 stainless steel and food-grade 304 stainless steel

304 stainless steel is a non-magnetic stainless steel material that contains 18% chromium and 8% nickel and is widely used to make kitchen and bathroom equipment and utensils. Food-grade 304 stainless steel refers to 304 stainless steel that meets the standards of the US Food and DrugAdministration (FDA) and is commonly used in the food manufacturing and processing industries. Food-grade 304 stainless steel requires special surface treatment to ensure that its surface is smooth, not easy to breed bacteria and dirt, and easy to clean and disinfect.

304 food-grade stainless steel genuine mark

‌ The genuine mark of 304 food-grade stainless steel is SUS304. ‌‌

304 stainless steel is a common stainless steel material, also known as 18/8 stainless steel, because it contains more than 18% chromium and more than 8% nickel. This material is widely used in industry, furniture decoration industry, and food and medical industries for its good corrosion resistance, processing performance and toughness. Food-grade 304 stainless steel is more stringent in composition, usually containing 18% to 20% chromium and 8% to 10% nickel to ensure its safety for food contact.

There are many ways to identify genuine 304 stainless steel, including the use of magnets and chemical testing fluids. In terms of magnetism, 304 stainless steel is an austenitic steel and is usually weakly magnetic, but may become magnetic after cold working. Chemical testing fluids can distinguish different types of stainless steel by observing the color change after being dropped on the surface of the stainless steel. Genuine 304 stainless steel will have little or no color change during testing.
