The durable and hygienic alloy has become a favourite in industries, domestic kitchens and even an architecture’s favorite for modern furniture. Stainless steel finds diverse use in processing of milk and dairy products, beer and wine making, confectionery, cooked meats and many more.

Until recently, stainless steel kitchen appliances were regarded as an expensive luxury in the modern kitchen. Good design, mass production and competition have changed the scenario. No wonder 30% of all stainless steel produced goes into products related to the food and beverage sector.

  • Is inert to alkalis and acids
  • Does not crack or break easily
  • Can withstand fire
  • It is more formable compared to other metals.

Applications of the various types of stainless steel in food industry

Stainless steel exhibits some of the most suitable characteristics of the construction materials used for food equipment. It is the most widely used material in direct contact with food found in the industry.

Application of Stainless Steel in food and dairy include:

  • Processing equipment such as pasteurizer, homogenizer, separator, decanter, metal detector, heat-exchanger, mixing tank and process tank etc.
  • Storage tanks and form equipment are consisted silo tank, road tanker, milking machine, cans and bulk milk cooler etc.
  • Accessories include the fittings, valve, pumps, and lab instruments etc.

In detail applications according to stainless steel best grades are:

Best grade Applications
420 (martensitic) Professional knives and spatulas
430 (ferritic) Table surfaces, equipment cladding, panel (ie components requiring little formability or weldability). Used for moderately corrosive environments (e.g. vegetables, fruits, drinks, dry foods, etc).
304 (austenitic) Vats, bowls, pipework, machinery parts (i.e. components requiring some formability or weldability). Corrosion resistance superior to 430.
316 (austenitic) Components used with more corrosive foods (e.g. meat/blood, foods with moderate salt contents), which are frequently cleaned, with no stationary solids and not under excessive stress.
1.4539 (austenitic) Used with corrosive foods (e.g. hot brine with solids that act as crevice forms, stagnant and slow-moving salty foods).
1.4462 (duplex) Used with corrosive foods (e.g. hot brine with solids, stagnant and slow-moving salty foods). Higher strength than austenitic. Good resistance to stress corrosion cracking in salt solutions at elevated temperatures.
6%Mo. types (austenitic) Used with corrosive foods (e.g. hot brine with solids, which act as crevice formers, stagnant and slow-moving salty foods). Good resistance to stress corrosion cracking in salt solutions at elevated temperatures. Used in steam heating and hot work circuits, hot water boilers, etc
