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. Perhaps the most important reason is that food-grade stainless steel.
Finishing stainless steel assemblies for handling food and beverage applications is more complicated than non-sanitary applications.
What makes stainless steel food grade. 316 makes for great food grade stainless steel containers for nearly any food application. Grade 430 Stainless Steel and Food. As an alloy stainless steel 430 food grade metal is very similar to grade 316 stainless.
It has the same chromium content as 316 but only a fraction of the nickel content which makes it a more affordable alternative for some food makers. Another major difference. Stainless steel covers an entire family of alloys mostly defined as iron alloys with more than 12 chromium so theyre relatively resistant to corrosion That ranges From high strength alloys like 138Mo and 440C that only pay lip service t.
This makes grade 316 stainless steel preferable for food makers that use salt or saltwater in their products. Temperature Extremes CAN Affect Food-Grade Stainless Steel. Most stainless steels have a melting point well outside of the temperature ranges typically employed in any food manufacturing process.
However it is still important to be careful of temperature extremes in your manufacturing. 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. 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.
What makes these two concepts different is that food grade contains the detail that temperature or environment will not impact the integrity of the material but that is not necessarily true for food safe materials. For example a plastic container may be food safe but it doesnt meet the criteria for food grade status because it cant withstand certain high. Stainless Steel Tables and Lecterns The 304 grade stainless steel we use has no pores or cracks that may harbour dirt grime or bacteria.
This flexibility makes stainless steel the perfect option for bespoke designs whether thats an adaptation on a theme or a piece of furniture made entirely from scratch. One of our core products since the beginning our tables have withstood the test of. Broadly speaking the two versions of food grade stainless steel.
Grade 316 and Grade 430 share the corrosion resistance that is common to all stainless steel both being made of an alloy consisting of iron nickel and chrome. Beyond that they both share these other qualities which are important to food processors. There are many different types of food-grade stainless steel each containing different compositions and properties.
The two most common types are 304 and 316L. Also known as 18-8 stainless steel because it contains 18 chromium and 8 nickel 304 is the most common stainless steel. 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.
This steel grade is especially suitable for food because of its high resistance to acids alkalis and chlorides such as table salt. Other austenitic stainless steels ie. 304 may develop strong pitting corrosion.
316 is not affected by this type of corrosion and is therefore suitable to most applications. 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. Chromium content is what makes steel considered stainless. Food-grade stainless steel must be smooth.
The surface cannot have any cuts cracks or other blemishes. If there are blemishes food particles may get stuck in the cracks even after being cleaned. No all stainless steel are NOT food grade or quality.
Non-magnetic 300 Series Grade 304 188 and 1810 are the two most common grades of stainless steel used for food preparation and dining. The 304 Grade are part of the 300 Series. FeedbackGrades of Stainless Steel that are Safe for Food.
Photo by Carlo Mendoza. There are 150 grades of stainless steel but your container cup or plate should be made from one of. Finishing stainless steel assemblies for handling food and beverage applications is more complicated than non-sanitary applications.
Knowledge of the tools consumables and techniques is critical but likewise the contractor must be familiar with sanitary standards so the system and its finish are optimal the demands for this type of application. Food grade stainless steel is steel that is resistant to wear and tear and has heat resistance in such a way that its safe for the use of cooking various types of food. There are a number of different grades of steel such as 1810 188 etc.
What this grade means is the amount of chromium and nickel.
