Stainless steel is made by adding chromium, nickel, and molybdenum in different proportions to the iron-carbon alloy.
Steel grades differ in the content of all these additives.
Stainless steel trolleys are manufactured from stainless steel that has at least 10.5% chromium, so it can be made with steel grades 304, 316, and 430.
316 stainless steel grade protects the best against salt spray, certain acids and bases, and high temperatures because of its higher concentration of molybdenum.
Grade 316 is, thus, really good for cooking and medical uses.
Grade 304 is cheaper and more common in general use than grade 316, and it is also very durable.
There are also 316L or 304L stainless steel grades.
Grades 316L and 304L have a lower carbon content, making them a little bit stronger.
However, these types of steel are not very frequently used in the market.
Steel grade 430 is also very popular and cheap, but less durable than grades 304 and 316.
Grade 430 is less resistant to corrosion, although it has a high concentration of chromium.
We especially recommend grades 304 and 316 for stainless steel trolleys: because one is cheap and the other is exceptionally durable.
