Composition of 4340 Alloy Round Bar

Several elements within a 4340 hot rolled round bar give it the strength and durability our clients require. With an iron-chromium alloy base, it is also composed of:

  • Silicon

  • Nickel

  • Vanadium

  • Manganese

  • Molybdenum

Industries That Use 4340 Round Bar

This round bar is a popular choice due to its superior strength and resistance to fatigue. It is desirable for high-stress applications in several industries:

  • Automotive

  • Aerospace

  • Oil and gas

  • Military

  • Construction

Another property that makes it a prevalent choice in these industries is its machinability. When in the annealed condition, many traditional machining methods can be used to machine the metal to precision. When it is heat-treated and at a higher heat, machinability does decrease and different tools are recommended to get the job done correctly and safely.


Applications for 4340 Steel Alloy Round Bars

Available in both hot and cold finishes, the 4340 round bar is excellent at resisting corrosion. It is strong, tough, durable, low weight, and immune to embrittlement, making it perfect for a variety of applications. At Ohio Bar & Metal, we easily produce these in high quantities, making it a cost-effective solution for:

  • Crankshafts and gears

  • Power transmission parts

  • Truck frames

  • Aircraft landing parts

  • OIl and gas shafts

A 4340 alloy round bar will not rust, discolor, or tarnish. This makes it perfect for all-purpose applications, as well as finished parts that aid in aesthetics.
