The most commonly used in the stainless steel series are 304 stainless steel and 316 stainless steel. 304 stainless steel is an austenitic stainless steel, a versatile stainless steel, which is widely used to make equipment that requires good comprehensive performance (corrosion resistance and formability) And machine parts. In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 18% chromium and more than 8% nickel content. 304 stainless steel is a grade of stainless steel produced in accordance with American ASTM standards.
304 stainless steel has a tensile strength of about 550MPa and a hardness of about 150-160HB in the solid solution state. 304 cannot be strengthened by heat treatment and can only be strengthened by cold working, but after cold working, the strength, plasticity, toughness and corrosion resistance are improved. Performance will be greatly reduced.
304 stainless steel has better corrosion resistance 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 this type of stainless steel is very common in China, the name “304 stainless steel” comes from the United States. Many people think that 304 stainless steel is a model name in Japan, but strictly speaking, Japan’s official name for 304 stainless steel is “SUS304″. 304 is a versatile stainless steel, which is widely used in industries that require good comprehensive performance, such as: CNC lathes, stamping, CNC, optics, aviation, mechanical equipment, mold manufacturing, electronics, precision instruments, transportation, textile , Electromechanical, metallurgy, military industry, ships, chemical industry, hardware manufacturing, mobile phone industry, medical industry, etc.
