AISI 4024 Molybdenum Alloy Steel Chemical Composition & Properties, Grades, Table and Online Pdf

AISI 4024 in the molybdenum steel family is simply remarkable for its high strength and long-term resilience. Apart from carbon otherwise known as C, manganese, phosphorus, sulfur, silicon, chromium and molybdenum constitute its chemical composition with any slight variation in the percentages of these compositions affecting its production significantly. This compound has yielded a material that possess a great degree of hardenability and wear resistance that we see being used in industrial machines such as gears, pulleys, shafts and other machine components that work under very stressful conditions. Compared to AISI 4024, AISI 4340 possess remarkable mechanical features, for instance, high tensile strength, good ductility, and toughness. Similar to other grades, its properties are often arranged in table, chart and PDF documents in order to ease the engineer and the manufacturer in the decision to use a material and the considerations during design.

AISI 4024 Alloy Steel Chemical Composition And Grade Table

AISI 4024 is a carbon-based, stainless chromium-molybdenum alloy that has the reputation for its high hardenability and overall low-production costs. Chemicals that usually, on the basis of its structure, contain carbon, manganese, phosphorus, sulfur, silicon, chromium, and molybdenum are a typical example of this chemical composition. These alloys are widely applied in cases which need high strength and hanging resistance, e.g., transmittals, shafts, and axles. There is an ideal heat treatment scheme for AISI 4024 as it has excellent machined and welded characteristics. Such a table of grades shows descriptively the particular percentages of each element, and, consequently, ensures the required quality and performance in a variety of industrial settings.

Advantages and Disadvantages of AISI 4024 Molybdenum Alloy Steel

    Advantages:

  • High Wear Resistance: The material is used because it resists wear as well as abrasion in conditions of operation.

  • Impact Strength: Possesses decent rebound properties for shock absorption, particularly in instances where high quantities of force are experienced on a routine basis.

  • Corrosion Resistance: Exhibits some measure of immunity to specific forms of chemical erosion.

  • Dimensional Stability: Retains its stability while operating at different loads.

    Disadvantages:

  • Brittle at Low Temperatures: A known characteristic of this material is that it is quite prone to brittle fracture particularly at low temperatures.

  • Limited Weldability: Welding needs preheat and pw HT heat treatment after the welding operation.

  • Surface Treatment Challenges: Some surface treatments may not be so straightforward because depending on the composition of the metallic alloy, some elements may interact with others due to their chemical properties.

  • Cost: More costly than regular carbon steel material types owing to the additional alloying elements contained in them.
