Stainless Steel Grades used in Food Equipment

With our extensive experience of working with Stainless Steel, Bronte Precision support a number of different Food Preparation Equipment Manufacturers. The most popular grade of Stainless Steel and offered referred to as the ‘food grade’ is 316, but a wide range of different grades are used in different applications.

316 Austenitic – The most popular of the Stainless Steel grades in food application, 316 is used on components where corrosion resistance is needed. It’s quite often used with meats and other foods that will have a salt content.

304 Austenitic – Often components that require a higher level of abrasion resistance or weldability will be produced from 301. It provides a higher level of corrosion resistance when compared to other Stainless Steel grades like 430. Often used on components such as Vats, Bowls, Pipework and also machinery parts.

420 Martensitic – This is the grade of Stainless Steel that is most often used on professional chef’s knives and other cutlery.

430 Ferritic – This grade is used for moderate corrosive resistance and often in conjunction with vegetables, fruit and dry foods. 430 is often used in panels, table surfaces and equipment cladding.

1.4539 Austenitic – Used for parts where a higher level of corrosion resistance is used and often on machinery that handles slow moving and salty foods or hot brines.

1.4462 Duplex – Similar to 1.4539, but with a higher strength and able to perform at higher temperatures and a good resistance to stress corrosion.

6%MO. Types Austenitic – Often used in steam heating and other hot water parts for example Hot Water Boilers and Hot Work Circuits.
