What is the difference between steel and stainless steel?

304 steel and stainless steel are harmless to the body.

The specific differences are as follows:

First density specific gravity is not the same, followed by the degree of rust is not the same. Prices vary greatly, of course,

Ordinary 304 stainless steel is a kind of alloy, and 304 composite stainless steel is a combination of two or three kinds of alloy composite materials, often is the surface is 304, sandwiched between a layer of other materials, or is sandwiched three layers.

Thermos are generally made of stainless steel is very common, very common, like the stainless steel dining room utensils, stainless steel is harmless to the human body, the effect is the same to say that a certain steel is good for the body that is bullshit, dishonest businessmen cheat with stainless steel, there are many kinds of CR content more than 13% can be said to be stainless steel, General tableware with stainless steel is almost the same thickness is not the same, and do tableware cup steel must be stainless steel, this is common sense, what 304 steel do not know who is made up,

No matter the two are not the same they said 304 steel is also a kind of stainless steel, stainless steel is not a separate steel, and do the stainless steel cutlery cup is not 3969, etc. Everyone is the same steel level, is nothing more than a thick point a thin point, the surface treatment problem.
