AISI 302Cu Stainless Steel Chemical Composition Properties, Grades, Table and Pdf

AISI 302Cu is a stainless austenitic steel with totally unusual properties, characterized by high resistance to corrosion and very high strength. Usually, the chemical mixtures of stainless steel feature chromium, nickel, copper, and manganese which significantly high quality of steel. Furthermore, the range of grades are available in various forms of sheets, plates, bars or wires therefore covering many applications in different industies like automotive, building and food processing. In their dealings with chart and PDF documents that describe AISI 302Cu alloys in terms of chemical composition, mechanical properties, and corrosion resistance admittance profiles, engineers and manufacturers are very active. Making resources such as these available simplifies a designer's work by providing the capability of making efficient decisions on material selection, which in turn aids the durability and the performance in varied settings and environments.

AISI 302Cu Austenitic Stainless Steel Chemical Composition And Grade Table

AISI 302Cu is a well-known stainless steel with copper being its main constituent, hence the material is more corrosion-resistant and it also exhibits excellent mechanical properties. The chemical constitution is normally the type like chromium, nickel, and copper, and this is the reason would why it performs well when salts are present. These steels have a range of grades capable which represent different alloying elements and mechanical properties. Engineers relying on manufacturing charts and PDF documents for exact material selection based on its chemical makeup, categorization and mechanical properties, has been adopted in order to ensure proper application selection.

The Advantages and Disadvantages of AISI 302B Austenitic Stainless Steel


  • Corrosion Resistance: Copper alloy AISI 312C has an outstanding ability to resist corrosion in many conditions of corrosion, especially in acidic and chloride rich codes.

  • High Strength: It has got a high internal resistance so that it can be used for applications such as storages materials where one structure requires to be sturdy and not prone to breakage.

  • Ease of Fabrication: This steel type has the ability to be formed, welded, and machined easily, giving it an advantage in the form of controlling the manufacturing processes as well as customization.

  • Thermal Stability: Stainless steel 302Cu is the one which keeps its mechanical properties over wide range of temperatures, what features it as a perfect material for both high and low-temperature projects.

  • Cost-Effectiveness: This stainless steel grade, AISI 302Cu, is superior in terms of its ductility, weldability, and corrosion resistance when compared with some other stainless steel grades but at the same time, the features are more economical thus choosing it will be a wise idea for many industrial application.


  • Sensitivity to Stress Corrosion Cracking: AISI 302Cu might be liable to stress corrosion cracking in certain situations, which has to be taken into account during the implementation of the material.

  • Limited Heat Resistance: Although it could be considered to have a lower heat resistance than some higher alloyed stainless steels, this can be taken as a drawback especially in terms of its role in high temperature applications.

  • Reduced Toughness at Cryogenic Temperatures: The toughness of AISI 302Cu may be reduced with cryogenic temperatures, which in turn decreases the material suitability for such extreme cold situations.

  • Magnetism: Generally annealed, AISI 302Cu is often a non-magnetic grade steel but upon having a cold worked state, it may become partially magnetic, therefore, making it less suitable for some applications.

  • Surface Contamination: When exposed to high waters containing chloride, AISI 302Cu has a possibility of surface contamination and chloride pi levels if not maintained and monitored properly.
