304 Stainless steel is a common stainless steel material, the
density of 7.93 g / cm³; also called 18 / 8 stainless steel,
meaning contains more than 18% chromium and more than 8% nickel;
high temperature resistance of 800℃, with high processing
performance, high toughness characteristics, widely used in
industrial and furniture decoration industry and food and medical
industry. However, it should be noted that the food grade 304
stainless steel compared with the ordinary 304 stainless steel, its
content index is more strict. For example: the international
definition of 304 stainless steel is basically mainly containing
chromium 18% -20% nickel 8% -10%, but the food grade 304 stainless
steel is containing 18% chromium and nickel 8% chromium, allowing a
certain range of fluctuations, and limit the content of various
heavy metals. In other words, the 304 stainless steel is not
necessarily a food grade 304 stainless steel
Among the common labeling methods in the market are 06Cr19Ni10,
SUS304, among which 06Cr19Ni10 generally means national standard
production, 304 generally means ASTM standard production, and
SUS304 indicates daily standard production.
The 304 Is a universal stainless steel, which is widely used to
make the equipment and machine parts requiring good comprehensive
performance (corrosion resistance and molding performance). To
maintain the inherent corrosion resistance of stainless steel,
steel must contain over 18% chromium and over 8% nickel.304

product standard
For 304 stainless steel, the Ni element in its component is very
important, which directly determines the corrosion resistance of
304 stainless steel and its value.
The most important elements in the 304 are Ni and Cr, but they are
not limited to them. Specific requirements are specified by the
product standards. The industry commonly determines that as long as
the Ni content is greater than 8%, and the Cr content is greater
than 18%, it can be considered as 304 stainless steel. This is why
the industry calls this kind of stainless steel 18 / 8 stainless
steel. In fact, the relevant product standards have a very clear
regulation for the 304, and these product standards for different
shapes of stainless steel and some differences. Here are some
common product standards and tests.
In order to determine whether a material is 304 stainless steel, it
must meet the requirements of each element in the product standard,
as long as there is a material that does not meet, it cannot be
called 304 stainless steel.

The above four criteria are just a few common criteria, in fact,
ASTM and JIS have mentioned more than these 304 criteria. In fact,
each standard of 304 requirements are not the same, so to determine
whether a material is 304, the accurate expression should be said
whether it meets the 304 requirements of a product standard.
Material certificate should generally issue the following type of
report:
