304 Stainless Steel Tubing


Stainless steel is an alloy that is manufactured by adding a minimum of 11.5% chromium to iron. Other components such as nickel and carbon might also be present in the various grades of stainless steel.

304 stainless steel is one of the most widely used alloy steel. It contains a minimum of 18% chromium along with 8% nickel and a minimum of 0.08% carbon. It is a T 300 Series stainless steel which is highly resistant to corrosion and works extremely well at low temperatures.

304 stainless steel tubes and pipes are widely used in applications which require corrosion resistant tubing Pipes and tubes that are used in industries like refineries, chemical plants, food processing industries and paper mills are often subjected to extremely corrosive materials flowing through them. Stainless tubing made from 304 stainless steel serves extremely well here as it does not corrode easily on coming in contact with chemicals and acids. This maintains the purity of the materials flowing though the steel tubing and also ensures minimal maintenance costs.
304 stainless steel tubes are not suited for usage at temperatures between 800°F and 1650°F. At these temperatures this grade of steel is susceptible to carbide precipitation which can lead to corrosion and the general failure of the steel tubing being used.

304L and 304H steels and their Applications

Grade 304L stainless steel is similar to 304 apart from a slightly lesser amount of carbon content in it. 304L grade of steel has a carbon content of 0.03%, this effectively avoids any carbon precipitation. It does not require any post weld annealing and is thus used extensively in components having a heavy gauge. Grade 304H is the high carbon version of 304 steel and precludes any carbon precipitation due to high temperatures. Thus, this grade of steel can be used at all temperatures without any fear of corrosion or damage.

Applications of 304 Stainless Steel

304 stainless steel can be easily drawn and is therefore used in a number of stainless steel products. Cooking utensils such as saucepans and plates are often made with this grade of steel. It is also used in the linings of sinks, stoves and table tops as it can withstand the corrosive action of any acid that might spill on it. Steel manufacturers use it extensively for tubing purposes. It can easily be drawn into round stainless steel tubes and square tubing which are being used extensively in the pipes and tubing industry.
