What is the difference between food-grade stainless steel and ordinary stainless steel often mentioned in commercial kitchen equipment?

I believe that friends who have been in contact with commercial kitchen equipment often hear the term food-grade stainless steel. So what is the difference between food-grade stainless steel and ordinary stainless steel? It is estimated that many people will have this question, so today let SHINELONG Xiaobian briefly answer the difference between the two types of stainless steel for everyone. Definition and use Food-grade stainless steel: refers to stainless steel that meets the relevant national food safety standards and can come into contact with food without causing physical or chemical damage. It is usually used to manufacture food production equipment, tableware, kitchen utensils, etc. to ensure that food will not be contaminated during the food production process. Ordinary stainless steel: It is widely used in many fields such as industry, construction, furniture decoration, etc., and has relatively low requirements for heavy metal content and corrosion resistance. Composition and content Food-grade stainless steel: There are strict restrictions on the content of harmful alloy impurity elements such as lead, chromium, and cadmium to ensure its safety. For example, the lead content of food-grade 304 stainless steel is much lower than that of ordinary stainless steel, and other harmful elements must also be controlled within a safe range. Ordinary stainless steel: Although it also contains elements such as chromium and nickel to improve its corrosion resistance, the content of harmful elements is not strict. Performance and characteristics Food-grade stainless steel: It has excellent corrosion resistance and acid and alkali resistance, and can withstand the acid and alkali substances commonly used in food processing. At the same time, the surface is smooth and easy to clean, and it will not provide a hiding place for bacteria, thus ensuring the hygiene and safety of food. Ordinary stainless steel: Although it also has certain corrosion resistance and strength, it may vary depending on the purpose. For example, stainless steel used in the construction field may pay more attention to its strength and durability, while stainless steel used in the decoration field may pay more attention to its appearance and aesthetics. Implementation standard Food-grade stainless steel: It needs to comply with the "National Standard of the People's Republic of China/Sanitary Standard for Stainless Steel Tableware and Containers" GB9684-88 or other relevant food safety standards. These standards have clear provisions on the chemical composition, physical properties, and sanitary indicators of stainless steel. Ordinary stainless steel: It is produced according to different industrial standards or industry standards, which may vary depending on the application field. Price and application Food-grade stainless steel: Due to its higher safety and stricter production standards, it is usually more expensive. But it is widely used in food production and processing to ensure the safety and hygiene of food. Ordinary stainless steel: The price is relatively low and it is widely used in various fields such as industry, construction, furniture decoration, etc. Food-grade stainless steel and medical-grade stainless steel need to come into contact with the human body, so human safety is taken very seriously. It is necessary to ensure that no harmful substances to the human body appear under any circumstances. Therefore, the material cost is much higher than that of ordinary stainless steel of the same type. Therefore, food-grade 304 stainless steel is generally more expensive than ordinary 304 stainless steel. As catering equipment, commercial kitchen equipment must use a large amount of food-grade stainless steel. Today's commercial kitchen sharing ends here. I hope it can be helpful to everyone.
