302 Stainless Steel

302 Stainless Steel

302 Stainless is arguably the most common form of stainless on the market. Having high similarities to 304 stainless except with a higher carbon count than 304, the 302 remains just as versatile a stainless steel out there. Often it is used in strip and wire format with high toughness and comparable corrosion resistance. However, this stainless steel is not hardened by heat treatment and is usually annealed in addition to its easy fabrication and formability.


302 Stainless Steel Corrosion Resistance – 302 stainless steel provides useful resistance to corrosion on a wide range of moderately oxidizing to moderately reducing environments. The alloys are used widely in equipment and utensils for processing and handling of food, beverages, and dairy products. Heat exchangers, piping, tanks and other process equipment in contact with fresh water also utilize these alloys. Also, a large variety of applications involves household and industrial chemicals. The 18 to 19 percent of chromium which these alloys contain provides resistance to oxidizing environments such as dilute nitric acid. These alloys are also resistant to moderately aggressive organic acids such as acetic and reducing acids such as phosphoric. The more highly reducing environments such as boiling dilute hydrochloric, and sulfuric acids are shown to be too aggressive for these materials.

302 StainlessCorrosion Cracking – 302 is the most susceptible of the austenitic stainless steels to stress corrosion cracking in halides because of its relatively low nickel content. Stresses may result from cold deformation of the alloy during forming, or by roller expanding tubes into tube sheets, or by welding operations which produce stresses from the thermal cycles used. Stress levels may be reduced by annealing or stress relieving heat treatments following deformation, thereby reducing sensitivity to halide stress corrosion cracking.

Welding – All austenitic stainless steels are considered to be the most weldable of the high-alloy steels and can be welded by all fusion and resistance welding processes.
