The 304 stainless steel coil is made with 18 percent chromium and 8 percent nickel. It is a corrosion-resistant metal that is widely used for various applications. Because it has a low content of carbon (which could produce dangerous carbides), it is safe for use in applications involving the kitchen, such as sinks, saucepans and other kitchen equipment. In this case, it’s recommended that the service temperature not exceed 800 degrees F. It also has great resistance to intergranular corrosion, which can result from stress relieving or welding. This low carbon content and its formability allow it to be easily welded. It can’t be hardened using heat treatment, but cold working can be used instead to harden and strengthen this alloy.
304 stainless steel is used frequently for parts that require grinding, welding, machining, or polishing, and that require corrosion resistance. It’s an all-purpose metal that is used in a wide array of industries and applications. This includes dairy, food, beverage, and other food-related industries that require a high degree of cleanliness and sanitation. This material is also used for fabricating parts that handle dyestuffs, refined oils, inorganic chemicals, organic chemicals, and acids like acetic, nitric and citric.
For applications that require resistance to corrosion, 304 stainless steel can be used, but only when elevated temperatures aren’t being used. Another reason this metal is widely used is that it has great forming, drawing, and stamping abilities. The machinability rating of this metal is 45 percent B1112. The average cutting speed for this metal is 75 feet per minute. It can be easily welded using commercial processes with exception to hammer and forge welding. When welded, the metal is tough and ductile. After forging is completed, it’s recommended that annealing be performed in order to maintain maximum resistance to corrosion.
