Hardness test of 304 stainless steel
304 is the most commonly used austenitic stainless steel. In the solid solution state, its tensile strength is about 550MPa, and its hardness is about 150-160HB. 304 cannot be strengthened by heat treatment, but can only be strengthened by cold working, but after cold working While the strength is increased, its plasticity, toughness and corrosion resistance will be greatly reduced. I don't know what to use, but there are many materials that can reach 60HRC, but the characteristics of the materials are quite different, and they must be selected according to the application. 304 stainless 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 stainless steel has excellent corrosion resistance and good resistance to intergranular corrosion. For oxidizing acids, it was found in experiments that 304 stainless 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 stainless 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-grade stainless steel tableware, outdoor stainless steel railings, etc.  Although this kind 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 kind of universal stainless steel, which is widely used in the production of stainless steel requiring good comprehensive performance.
