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

AISI 304H is austenitic stainless steel alloy that is specifically appreciated by the industry for its relatively high carbon content allowing the material to have more high-temperature mechanical property retention at elevated temperature. Usually, the chemical content comprises of chromium, nickel, manganese, silicon, carbon and the minor amounts of the other components, and this is one of the reasons why it has higher corrosion and mechanical resistance properties. AISI 304H results differ according to the carbon content and specific alloying elements which ultimately caters for varied situations across manufacturing industries such as food processing, chemical processing and pharmaceutics respectively. Extensive excel spreadsheets and pdf documents such as grades, chemical compositions, and mechanical properties are really useful for engineers and manufacturers so that they can make the right choice for material selection, design improvements, and to achieve industry standards.

AISI 304H Austenitic Stainless Steel Chemical Composition And Grade Table

Table of AISI 304H austenitic stainless steel chemical composition and grade is precious guides for engineers and manufacturers to make alloy selection. This table mostly embodies the exact percentage of the chromium, nickel, carbon, manganese and some other alloying elements, in their given values. Besides this, it provides us with the relevant grades, depicting the changes in mechanical properties, corrosion resistance, and suitability in application-specific tasks. Providing access to this table, however, is critical in the decision-making processes during the material selection, due to its need to be compatible with various fields such as construction through food processing among others.

The Advantages and Disadvantages of AISI 304H Austenitic Stainless Steel

    Advantages:

  • Corrosion Resistance: AISI 304L is an alloy that is corrosion resistant in the marine environments, various chemicals and food processing, so it can suit maker in these environments.

  • Weldability: This heat resistant steel has a good welding ability, which promotes easier fabrication and construction that meet the wide range of applications.

  • High Temperature Performance: AISI 304L stainless steel does not lose its tensile strength and remains intact at temperatures above normal which makes it ideal for high temperature applications like heat exchangers and exhausts.

  • Hygienic Properties: Its smooth, non-corrosive and non-stain surface make it suitable for sanitary areas like in food processing and pharmaceutical factories.

  • Versatility: AISI 304L is extremely versatile that it is available in different forms like sheets, plates, pipes and fittings, among the less number, and this makes it ideal for different industrial and commercial uses.

    Disadvantages:

  • Lower Strength: Compared with some other alloy grades of stainless steel, AISI 304L possesses a lower tensile strength, after which it is not recommended for the use in the high-stress cases.

  • Sensitivity to Chloride: Despite being heavily resistant to corrosive agent, AISI 304L also has a susceptibility to pitting corrosion in chloride-rich environments that should be considered while making appropriate decisions.

  • Susceptibility to Stress Corrosion Cracking: There exist some atypical cases whereby AISI 304L get susceptible to stress corrosion cracking when they are exposed to chloride solutions at high temperatures.

  • Cost: Whereas it is not too expensive but it may be higher in its initial cost to grocery as compared to other materials thereby the large-scale projects budget considerations may be negatively affected.

  • Limited Hardening by Heat Treatment: We should note that AISI 304L material is not heat treatable, which may limit its use in the app which need higher hardness and wear resistance.
