Standard regulations. The common industry judgment considers that as long as the Ni content is greater than 8% and the Cr content is greater than 18%, it can be regarded as 304 stainless steel. This is also why this type of stainless steel is referred to as 18/8 stainless steel in the industry. In fact, there are very clear specifications for 304 in relevant product standards, and these product standards have some differences for stainless steel of different shapes. Below are some common product standards and tests.

To determine whether a material is 304 stainless steel, it must meet the requirements for each element in the product standard. If any one does not comply, it cannot be called 304 stainless steel.
