AISI 316H Stainless Steel Chemical Composition, Grade, Charts and Online Pdf

AISI 316H is the high-carbon variant of the austenitic stainless steel grade 316 that became wildly popular. Chromium, nickel, molybdenum, and carbon are the chemical constituents. They have high ambient and temperature corrosion resistance and so are placed in highly resistant steel. Composite steel consists of 16%-18% chromium, 10%-14% nickel, 2%-3% of molybdenum, and 0.04%-0.10% of carbon. With this alloy, there is good weldability and formability which makes it suitable for so many applications in all sorts of industries like chemical processing, pharmaceutical and also marine engineering. However, these conditions lead to loss of sterling and the decrease of its weight in silver in future years. Often, engineers and designers, as well, scrutinize the AISI 316H chemical composition charts, tables and PDF, with the aim of establishing the particulars of this material and its appropriateness for a particular project.

AISI 316H Austenitic Stainless Steel Chemical Composition And Grade Table

AISI 316H is an austenitic stainless steel well known for two reasons namely high chemical and high temperature strength. Its chemical substances consists of mainly chromium, nickel, and molybdenum, ensuring longstanding corrosion protection, especially in chloride containing surroundings. Grade 316H featuring a higher content of carbon than the standard 316 stainless steel, it provides better creep resistance. The standard composition for a type-304 stainless steel typically ranges between 17%-20% chromium, 10%-14% nickel, 2%-3% molybdenum, and up to 0.1% carbon. The AISI 316H alloy composition is perfectly suited for diverse use cases by different industries like chemical, petroleum refining, and marine because of its ability to withstand corrosive environments.

The Advantages and Disadvantages of AISI 316H Austenitic Stainless Steel

    Advantages:

  • Corrosion Resistance: AISI 316H stainless steel displays as much as possible corrosion resistance in different environments such as acidic and high-temperature ones.

  • High Strength: It has a good tensile strength and durability, making it a great choice to apply in structural spaces where strength is essential.

  • Formability: AISI 316H is a material that is easier to form and manufacture into different shapes enabling for diverse construction.

  • Weldability: Its low carbon content not only improves weldability, but also facilitates assembly and welding processes. Consequently, working with it would be less complicated.

  • Temperature Resistance: AISI 316H offers amazing performance at high temperatures because it is stable and reliable under extreme conditions.

    Disadvantages:

  • Magnetic Properties: AISI 316 stainless steel is commonly magnetically by the mild magnetic effect what can lead to the rejection by some applications where magnetism is not required.

  • Work Hardening: It works prone to over hardening under forming operations and thus resulting in the loss of ductility that could be regained by annealing or heat treatment.

  • Cost: For instance, other for grades than AISI 316H stainless steel can cost relatively a lot, so the affordability is affected in some applications.

  • Surface Finish: Getting any given smooth surface finish can be difficult especially when the work-hardening property of this material is relocated at machining stage.

  • Sensitivity to Chloride: AISI 316H is at risk of getting localized corrosion in chloride rich, surroundings, so it is essential to take a cautious approach when choosing this alloy for marine or coastal structures.
