304 steel is a universal stainless steel material, and its rust resistance is stronger than that of 200 series

stainless steel materials. The high temperature resistance is also relatively good, and the general operating

temperature limit is less than 650 °C. 304 steel has excellent stainless corrosion resistance and good

resistance to intergranular corrosion. For oxidizing acids, it was found in the experiment that 304 steel has

strong corrosion resistance in nitric acid with a concentration of ≤65% below the boiling temperature.

It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids.
304 steel is a very common stainless steel, also known as 18/8 stainless steel in the industry. Its corrosion

resistance is better than 430 stainless steel, but the price is cheaper than 316 stainless steel, so it is widely

used in life, such as: some high-end stainless steel tableware, outdoor stainless steel railings, etc.

Although 304 steel is very common in China, the name "304 steel" comes from the United States. Many people

think that 304 steel is a model name in Japan, but strictly speaking, Japan's official name for 304 steel is "SUS304".

304 steel is a general-purpose stainless steel that is widely used to make equipment and parts that require good

overall properties (corrosion resistance and formability). In order to maintain the inherent corrosion resistance

of stainless steel, the steel must contain more than 16% chromium

316 (0Cr17Ni12Mo2) stainless steel seamless pipe

316 is a molybdenum-based austenitic stainless steel, which has advantages over conventional chromium-nickel

austenitic such as 304 stainless steel.

Better resistance to general corrosion, pitting corrosion and crevice corrosion. 316 has higher ductility, stress

corrosion resistance, compressive strength and high temperature resistance. In addition to excellent corrosion

resistance and strength, 316 also has the good assembly and formability of austenitic stainless steels.
