Why do stainless steel water pumps use 304 stainless steel, which is commonly known as "stainless steel" or "acid resistant steel"? It not only does not rust, but also has resistance to acid and alkali corrosion. All stainless steels can resist rusting, but their ability to resist corrosion and mechanical strength varies. Based on this ability, they are further classified into different grades 201304316430
Food grade issues
In terms of material, the content of 304 material has reached food grade. There are approximately three common food grade materials in the market: 304, 316, and 430 stainless steel. 304 is commonly used in small household appliances or water cups, 316 is sometimes used in medical devices, and 430 is often made of stainless steel material for cutting tools. It's not that the material is food grade, it's food grade. It also includes whether the manufacturing process meets food grade standards. Sokon stainless steel water pumps will adopt different process plans based on the pump's function and usage environment, striving to achieve cost-effectiveness and optimal functional requirements. Household all stainless steel water pumps can reach food grade and will not cause secondary pollution to water quality.
