AISI 304N Stainless Steel Chemical Properties, Grade, Table and Online Pdf

AISI 304N, an austenitic stainless steel series with high nitrogen content, showcases not only its enhanced mechanical properties but also good corrosion resistance thanks to which it can be used in difficult conditions. It normally consists of chromium, nickel, carbon, and nitrogen, thus, a balance of hardness and resistance to corrosion is achieved. Charts and PDF documents on pages that selectively provide the necessary grade, chemical composition and mechanical properties that are used by engineers, designers and manufacturers in precise material selection are quite beneficial. The key benefits of AISI 304N are its superior mechanical strength, enhanced corrosion resistance, wider adaptability across diverse conditions, and huge supply availability. Nevertheless, possible obstacles could include increased costs and low supply of AISI 316 compared to conventional grade 304 resulting from the procurement and design process that needs to be taken into consideration.

AISI 304N Austenitic Stainless Steel Chemical Composition And Grade Table

The AISI 304N austenitic stainless steel chemical composition and grade table are an indispensable resource for engineers and manufacturers. These tables usually show the percentages of elements, such as chromium, nickel, carbon and nitrogen that affect the material’s constituent and therefore its properties. This system groups the grades according to variations of the mechanical properties, corrosion resistance, as well as applicability of the materials for particular uses. Material selection procedure is simplified since the graph is at hand and the desired grade for the particular application is identified. It functions as the overall checklist that analyses the project needs and performance standards.

The Advantages and Disadvantages of AISI 304N Austenitic Stainless Steel

    Advantages:

  • Excellent corrosion resistance: AISI 304N stainless steel is an outstanding option in terms of corrosion resistance which makes it universal for various environments like marine and chemical.

  • High strength: It exhibits good tensile and yield strength along with strong structural applications, where strength demands are the main consideration.

  • Enhanced weldability: AISI 304N, a weldable stainless steel with higher weldability than traditional levels, can help to reduce fabrication and assembly time.

  • Good formability: This is because it can be given different shapes and sizes, which allow for its usage in different types of mass production.

  • Elevated temperature resistance: AISI 304N, in turn, exhibits higher mechanical property at elevated temperatures and hence can cope with challenging conditions.

    Disadvantages:

  • Cost: First of all, the higher initial price than some other grades may be a downside for some level cost sensitive applications.

  • Sensitivity to chloride environments: It serves this function very well but can be easily damaged and may require regular maintenance especially if it is situated in areas with high chloride levels such as the beach.

  • Susceptibility to pitting corrosion: In an aggressive environment, surface defects may be observed on AISI 304N, which will make material selection and surface treatment careful.

  • Limited heat treatment options: Its material structure causes restriction on intensity of heat treatment that could be a disadvantage when parts needed for certain applications must have specific mechanical properties.

  • Magnetic properties: When compared with other austenitic stainless steels, 304N may exhibit slight magnetic properties attributed to its nitrogen content that in some applications where non-magnetic properties are critical may have negative effects.
