Features of stainless steel which make it best for foodindustry
Machines and tools used in the canning industry, as well as those used in catering and restaurants, must meet strict hygiene standards. Stainless steel is almost always the only choice in these areas, thanks to its corrosion resistance. Each alloy has its strengths and weaknesses, and manufacturers must wisely choose from hundreds of stainless steel grades.
Making sweets is not the same as making cheese: the temperature, and especially the chemical composition, is different. Same is with steel; its making process is different from other metals. The most widely used alloys in food processing are AISI 316 and AISI 430.
High tensile fasteners manufacturers in India produced Stainless steel cutlery that has been around since the 1910s. When General Electric began promoting stainless steel dishwashers, vertical two-door refrigerators, and kitchen products embedded in TV commercials and materials in the late 1980s, stainless steel in kitchens became a really common name.
Stainless steel in the food industry
For over a century, Stainless Steel 304 Bolts have repeatedly proven to be a food-safe material. After all, it does not corrode, rust, or provide a habitable condition for harmful pathogens. From a hygienic and durable standpoint, the discovery of stainless steel in the 20th century remains a sensation in the food and beverage industry.
And if you're looking forward to today, you'll find that Grade 8.8 Bolts is used in a wide range of commercial food applications long before and after cooking.
Many of our foods today are indeed processed, disinfected, and packaged before arriving in supermarkets and kitchens. And all this process must be done in hygienic conditions.
AISI 316 Stainless Steel
316 is an austenitic Grade 10.9 Bolts rich in chromium and nickel. Like most metals, it has a much higher usable temperature range than is required for food preparation.
This grade of steel is particularly suitable for food because of its high resistance to chlorides such as acids, alkalis, and table salts. The 316 is not affected by this type of corrosion and is suitable for most applications.
AISI430 Stainless Steel
It has the same chromium content but is cheaper due to the lower proportion of nickel.
Another important difference is that AISI 430 is a ferrite alloy, a magnetic material. Ferrite alloys are highly resistant to stress corrosion cracking and can fail in the presence of mechanical stress in a corrosive environment.
Stainless Steel 316 Bolts is used for contact with acidic foods due to its high resistance to organic acids and nitric acid. It also has excellent resistance to oxidation and sulfur.
On the other hand, low nickel levels make some foods and juices less resistant to reducing acids.
What is the best food-grade stainless alloy?
In general, AISI 316 is ideal for machines and containers used in the canning and catering industry. It is an excellent solution because it is resistant to salt and acidic foods such as tomatoes and lemon juice. For less demanding applications, the AISI 430 can be a cheaper (and equally valid) trade-off.
