Food grade stainless steel is made from different metal alloys and elements depending on the properties desired for the stainless steel such as. Food grade stainless steel refers to the stainless steel material that meets the requirements of the National Standard of the Peoples Republic of China Sanitary Standard for Stainless Steel Food Containers GB 9684-88 and its lead chromium content is much lower than that of ordinary stainless steel.
This grade can be found in most kitchen equipment because of its resistance to corrosion.
What is food grade stainless steel. What is food grade stainless steel made from. Food grade stainless steel is made from different metal alloys and elements depending on the properties desired for the stainless steel such as. Food Grade Stainless Steel 316 Grade 316 stainless is an austenitic stainless steel alloy with a high chromium and nickel content.
Like many steel alloys it has a continuous use temperature several times higher than most food making processes will ever require more than 800C or 1472F. Stainless steel is famous for being able to resist corrosion but just because the surface of the steel looks shiny and smooth doesnt mean that its food-grade. To meet key sanitary standards the finish of the steel MUST eliminate any surfaces that could result in bacterial growth while being easy to.
Food-grade stainless steel is often used for kitchen equipment which can be costly to install. But because most grades of stainless steel are highly corrosion-resistant the equipment does not need to be replaced as frequently. Food-grade stainless steel is extremely strong making it an excellent material to use in heavy-duty equipment or in shelving for storage areas.
Food Grade Stainless Steel. Stainless steel is a popular metal for manufacturing cooking utensils because its very stable and highly resistant to corrosion. Additionally stainless steel easily forms into the desired shape and can be finished or polished to a decorative sheen.
Acidic foods such as lemons and tomatoes can react badly with some pans. 188 and 1810. These are the two most common grades of stainless steel used for food preparation and dining also known as Type 304 304 Grade and are part of the 300 series.
The first number18 refers to the amount of chromium present and the second represents the amount of nickel. For example 188 stainless steel is comprised of 18 chromium and 8 nickel. Generally speaking food-grade stainless steels boast surfaces that are much less permeable and much smoother than the others.
For example these special forms of stainless steel must be able to withstand acids alkalis and chlorides such as salt which is frequently introduced to a steels surface during processing. Grade 188 steel is made of 18 chromium and 8 nickel which is added to about 08 carbon and roughly 50 iron. The term 188 comes from listing the chromium amount as the first number and the nickel amount as the second.
This is generally how you can tell the amount of chromium and nickel present in different types of stainless steel. On the other end of the spectrum is food grade material such as food-grade stainless steel which has been deemed suitable to come in direct contact with food products. This implies that the surfaces cannot contain any toxic components.
They must also be designed so that the end user can follow these cardinal rules. The material is used within the recommended safe temperature range. Food grade stainless steel refers to the stainless steel material that meets the requirements of the National Standard of the Peoples Republic of China Sanitary Standard for Stainless Steel Food Containers GB 9684-88 and its lead chromium content is much lower than that of ordinary stainless steel.
This is often 300-series when it comes to cookware. This is because 300-series stainless steel contains both chromium and nickel creating what we refer to as food grade. Chromium is what makes stainless steel resistant to rust.
The nickel content is part of what helps the cookware to resist corrosion as well as chromium. Why is stainless steel used in the food industry. For many sanitary food handling applications stainless steel is a popular material choice.
Not only can food-grade stainless steel stand up to harsh temperatures that would melt plastic the materials protective oxide layer helps prevent the formation of rust that could contaminate foods. Perhaps the most important reason is that food-grade stainless steel contains. Food-grade stainless steel is often used for kitchen equipment which can be costly to install.
But because most grades of stainless steel are highly corrosion-resistant the equipment does not need to be replaced as frequently. Food-grade stainless steel is extremely strong making it an excellent material to use in heavy-duty equipment or in shelving for storage areas. What Determines Food-Grade.
For a stainless steel to be Food Contact Substances FCS approved the Food and Drug Administration FDA National Science Foundation NSF and American National Standards Institute ANSI require that it must have minimum chromium content of 16. In general three series of stainless steel meet these requirements. SAE 200 chromium-nickel-manganese alloys.
In the majority of applications a finish at the high end of No. 4 is considered food grade see Stainless Steel Finishes sidebar. This finish is achieved using a high-grit abrasive in the range of 150-220 and is identified by short parallel lines that run the length of the material.
Therefore in the national standard GB9684-2011 National Food Safety Standard Stainless Steel Products the grade requirement is cancelled and only heavy metal precipitates are required. Therefore the stainless steel used in tableware today does not require grades but at the same time as long as it can meet the requirements of food Grade it must be able to reach at least the level of. The most commonly used stainless steel for food processing is 304 grade stainless steel.
This grade can be found in most kitchen equipment because of its resistance to corrosion. The chromium content will prevent the equipment from rusting.
