In older plants and equipment were made of carbon steel or aluminum in food processing units. Carbon can easily rust and may cause high replacement cost. Aluminum can be scratched easily as it has soft surface. Both of these can create major issues in Food and beverage production.
Stainless steel will not easily get rust; its main advantage is corrosion resistant and temperature resistant. Stainless steel can withstand high temperature and pressure.
In food manufacturing, cleaning and sanitation are supreme. When it comes to equipment, it is important to understand what materials to use and how selection can affect fabrication design and future care.

Stainless steel finds diverse use within the processing of milk and dairy products, beer and winemaking, confectionery, cooked meats, and plenty of more.
Metals, particularly, offer exceptional strength properties necessary for top production volumes. But strength isn't the sole factor to consider. The most effective materials should be as non-corrosive and inert as possible.
The most common grade of stainless-steel used in processing and packaging ...
... applications is 316/L, or what many refer to as “food-grade stainless”. Many other stainless alloys like 304/L, 347, 409, and Duplex may also be utilized in machinery and equipment for this industry.

Stainless steels are widely employed in the food industry because of their inherent resistance to corrosion. It is often formed into complex shapes. From tools to surfaces, this metal is extremely suitable for production, processing, and packaging.
Stainless steel will be cleaned and sterilized without deterioration. It also doesn't impart any color and flavor to food, making it ideal for the food industry.

Benefits of using Stainless Steel in food industry:
 It is resistant to varying temperatures:
It is often used easily in both very cold and extremely hot temperatures. This makes it perfect for all aspects of food and beverage production.
 Rust-Resistant
It can be washed down in a high-pressure water system without worry about the moisture damaging the equipment’s surface. For people and businesses working within the food processing industry, this benefit is priceless.
 Easy Fabrication
As for the fabrication of stainless-steel, there are many various ways in which it may be manipulated. It can be cut, welded, and formed quite easily, especially with more current metal-working techniques. This makes it suitable to create small tools also as large appliances.
 Durability and Strength
By nature, steel is one among the foremost durable metals on the market. Not only is it less susceptible to physical damage, but it's also resistant to corrosion, moreover as wear and tear associated with aging. While other metals must be maintained during use, stainless-steel will likely need fewer professional repairs.
 It's easy to clean
If you're working with food and beverages, maintaining a clean environment is very crucial. It is easy to clean wipe clean and does not easily breed bacteria.

Application of stainless-steel in food and dairy include:
 Austenitic grades are utilized in the manufacturing of cutlery, hollow-ware, and kitchen utensils. Other applications include brewing vessels, milk tankers. Grades containing Molybdenum are resistant particularly to salt-containing food. 316L/1.4404 is named as “food grade” because of its diverse use within the food industry. Similarly, 304L/1.4307 is additionally an awfully popular grade to be used in food industry applications.

 Ferritic stainless steel is employed in appliance manufacturing (dishwashers, refrigerators, and ovens). Another advantage of this grade is its affordability. The value of 1.4016 is significantly less than austenitic grades, thus making it a cost-friendly choice. They’re particularly good in highly oxidizing environments (e.g. nitric acid) and offer excellent resistance to stress Corrosion Cracking. However poor formability and weldability limit the utilization.

 Martensitic grades have high levels of carbon. This sort of stainless-steel is hard enable by heat treatment. The grade is employed in applications where high wear resistance is desired. 420/1.4021 could be a popular grade for the manufacturing of knife blades. For superior quality knives which retain sharpness even after prolonged use, grade 1.4116 may be used.

 Duplex grades are preferred for handling corrosive foodstuffs as they provide high resistance to corrosion caused by saline solutions at high temperatures. This grade is mainly used in custard and vinegar making, manufacturing of sauces, cheese dairies, and fish-canning plants.

Bottom Line
Stainless Steel machinability and other properties make it a greater option for food processing, as well as a multitude of other industries. Selection of metal and alloys used in food and beverages industry is a very crucial decision. Right grade of stainless for right application will help to maintain the overall life cycle cost.
