This 18/0 stainless steel may tarnish due to this grade of stainless steel containing almost no nickel. Nickel is added to stainless steel to protect against corrosion and to give stainless steel its shine. For those wishing to avoid nickel, 18/0 grade stainless steel is ideal.
Not recommended for the dishwasher. As this stainless steel contains no nickel it has reduced corrosion properties. Dry immediately after washing.
What is the best quality stainless steel? Stainless steel is an alloy made up chromium, steel iron (often mined in Australia), molybdenum, nickel and other metals. The number of the grade refers to the amount of chromium and nickel in the product. 18/0 (18% chromium, no nickel), 18/8 (18% chromium, 8% nickel), 18/10 (18% chromium, 10% nickel). Nickel is added to protect against corrosion and to give stainless steel its shine.
Type 304 or Grade 304 stainless steel covers the numbers 18/8/, 18/10, which are the most common grades of stainless steel used for food preparation, dining and utenstils. 18/0 stainless steel contains almost no nickel (and thus not magnetic), making it more likely to rust athough still high quality.
Food containers and lunch boxes made from 200 type stainless steel are quite common because 200 is less expensive than 304 grade due to manufacturers substituting manganese for nickel. Although food safe, they are not as resistant to corrosion and not as high quality.
