With a high level of carbon, 440 stainless steel is one of the strongest types used in the kitchen. Products made out of 440 stainless steel are hard, corrosion resistant, and can stand up to wear and tear very well.
What is the difference between duplex and stainless steel?
The main differences in composition, when compared with an austenitic stainless steel is that the duplex steels have a higher chromium content, 20–28%; higher molybdenum, up to 5%; lower nickel, up to 9% and 0.05–0.50% nitrogen.
What is the difference between Hastelloy C22 and C276?
The major difference between Hastelloy C22 and C276 is that the Hastelloy C22 is very important due to its enhanced versatility and exceptional resistance to chloride-induced pitting whereas the Hastelloy C276 is very important due to its proven performance in a wide range of aggressive chemicals.
What is the difference between Hastelloy and Inconel?

What is Monel made of?
Now, the Monel 400 trademark is owned by Special Metals Corporation and it is primarily composed of 52 – 67% nickel (Ni) and copper (Cu), with small amounts of iron, manganese, carbon, and silicon.
Why is austenitic steel?
Austenitics are best known for its corrosion resistance which is why they are often used for stainless steel applications. Making up more than 70% of steel production, they are also one of the most commonly used stainless steels, with grade 304 being by far the most preferred type.
What are austenitic steels used for?
Austenitic stainless steels are used for domestic, industrial, transport, and architectural products based primarily on their corrosion resistance but also for their formability, their strength, and their properties at extreme temperatures.
How is austenitic steel made?
Steel is created when iron is alloyed to carbon, producing a strong, ductile, but rust-vulnerable alloy. Chromium is added to help create a passive oxide layer and prevent rust. … With all these elements, austenitic stainless steel is created: non-magnetic, heat and cold tolerant, ductile, and weldable.
