AISI 314 Stainless Steel Chemical Properties, Grade, Chart and Pdf

The austenitic stainless steel AISI 314 has extremely high strength even at high temperature levels and outstanding resistance to oxidation. Most steels are built with blends of roughly 25% chromium, 20% nickel and silicon in it, which makes it tough to be functional even in extreme environments of elevated temperature. The AISI 314 alloy is normally used in the manufacturing of many furnace parts, heat exchangers and radiant tubes where it can withstand extremely high temperatures of close to 2100°F (1150°C) without losing its mechanical properties. The grades of offered product compliantly to those given by the AISI and its forms include sheets, plates, bars, and pipes. While working under the AISI 314 is the preferred one for its heat solidness by the engineers and designers. The downloadable charts and tables, as well as the PDF files, have all the specifications for this versatile panel.

AISI 314 Austenitic Stainless Steel Chemical Composition And Grade Table

AISI 314 is a widely acknowledged austenitic stainless steel that merits its reputation for achieving high-temperature strength and excellent oxidation resistance, which makes it be the best for use of furnace components, heat treatment equipment, and other elevated-temperature conditions. Its chemical make-up usually contains at least 25% chromium, 20% nickel and 2% silicon which leaves it with excellent oxidation and scaling resistance at temperatures up to 1150degC. In addition to the AISI 314 enjoying good creep strength and thermal shock resistance.

The Advantages and Disadvantages of AISI 314 Austenitic Stainless Steel

    Advantages:

  • High Temperature Resistance: AISI 314 has unique contrast to the resistance of oxidation and scaling at higher temperatures, it can be used for high-temperature applications like furnace components and heat exchangers.

  • Corrosion Resistance: This material provides a good degree of resistance to corrosion in different media that include even slightly acidic atmospheres and aqua solutions.

  • Strength and Toughness: AISI 314 with good mechanical properties should provide the necessary strength and toughness in structural parts.

  • Weldability: It is type of material which is easily weldable through common welding methods, then manufacture processes and also gives strong and durable welding joints.

  • Thermal Stability: AISI 314 keeps its properties at very low temperatures, therefore this steel can be used in applications that require high pressure conditions like cryogenic storage tanks.

    Disadvantages:

  • Cost: AISI 314, being higher-grade than a conventional stainless steel; is comparatively expensive because of its higher alloy content and advanced properties.

  • Magnetism: It displays minimum magnetism sometimes which can be undesirable in some applications featuring non-magnetic material.

  • Machinability: Machine AISI 314 is a difficult job, which often require unique cutting tools and complicated technologies to accomplish needed shapes and dimensions.

  • Sensitization: If certain temperatures are encountered over a longer period then corrosion in such environments will increase as sensitiisation is impossible to avoid.

  • Limited Availability: Moreover, the AISI 314 may take longer to obtain from specialized suppliers, as it may not be as easily found as more common stainless steel grades.
