Regular manufacturers generally use 304 (i.e. 18-8) and 430 (i.e. 18-0) stainless steel as spork, 420J2 (i.e. 13-0) as knife, 430 and 420 as magnetic, and 304 as micro-magnetic. However, there is also a kind of tableware made of 20 1 and 202 on the market, which has not been magnetized, but the material of 20 1 and 202 contains high manganese and is not food-grade stainless steel.

There is also a 18- 10.

There are more and more chemical components in the air, and even 304 will rust in some seriously polluted places; Therefore, some advanced articles will be made of 10% nickel to make them more durable and corrosion-resistant. This kind of stainless steel is called 18- 10 stainless steel. In the description of some tableware, there is a statement similar to "using 18- 10 the most advanced medical stainless steel material".
