Stainless steel is known as a "green material" due to its 100% recycling rate (100% recyclable), making it one of the most earth-friendly metals used in a range of industries including chemical, process, oil and gas, shipbuilding , power plants, electronics, aviation and other high-tech industries. Contains chromium, carbon and other alloying elements such as nickel, manganese, titanium, niobium, molybdenum, etc., which enhances the corrosion resistance of the material. 304 stainless steel has chromium as the base metal, which forms a thin coating on its surface to protect it in corrosive environments.
There are more than 150 grades of stainless steel such as SS304, SS316, SS327, etc. According to the internal structure of the metal at room temperature, it is divided into five categories: austenite, ferrite, martensite, duplex and precipitation. SS304 is one of the most widely used stainless steel grades due to its excellent versatility. Let's take a look at its composition and applications in a range of fields.
stainless steel 304
304 stainless steel is one of the most common grades of stainless steel, containing chromium (18% – 20%) and nickel (8% – 10.5%) metals and their major non-ferrous constituents. SS 304 belongs to the austenitic class of the stainless steel family and has excellent corrosion resistance compared to other steel grades and has higher formability.
Steel can be easily molded into desired shapes and cut to standard and preferred sizes. However, 304 stainless steel does not conduct electricity or heat very well, and is less magnetic than other stainless steel grades.
Characteristics of 304 stainless steel
Stainless steel retains its shape and exhibits excellent resistance to external elements such as harsh environments or pollution.
SS 304 is very resistant to corrosion and any other aggressive media, making it one of the most used stainless steel grades in corrosive environments.
Stainless steel 304 exhibits resistance to pitting corrosion in water with chloride concentrations up to 400 mg/L at room temperature, decreasing to about 150 mg/L at 60°C.
Stainless steel is used in the design of household appliances and other items due to its aesthetic qualities, i.e. a shiny smooth surface.
SS 304 has excellent formability, making it one of the materials of choice for making kitchen utensils such as cookware.
It has excellent retention, especially at low temperatures at room temperature.
SS 304 does not require any post weld annealing to restore its corrosion resistance (in most cases). The low carbon content of steel makes it an ideal metal choice when it is necessary to keep carbide precipitation low.
