Ductile Iron Rectangle Bar Basics

Ductile iron rectangular bar is a high-performance, sturdy and versatile material with a lower overall cost than comparable carbon steels. Dura-Bar continuous cast ductile iron is easy to machine and has the following characteristics:

  • Superior corrosion resistance
  • Excellent fatigue strength
  • Superior machinability
  • Fine-grained surface finish
  • Heightened wear resistance
  • High thermal conductivity

Ductile iron rectangle bar is stocked in many sizes, from 2.250” x 3.250” to 20.000” x 25.600”. Stock length is 72”, but lengths up to 144” are available upon request. With our skilled employees and industry-leading equipment, I.T.S. can supply your cast iron needs cut to your specific dimensions quickly and efficiently.

As-cast rectangles are made to the actual size with no allowance for machine stock added. They are cast to actual dimension, with clean up stock dependent on the height-and-width ratio. See Dura-Bar’s Stock Allowance & Guaranteed Clean-Up Sizes for specific sizes.

Ductile Iron Rectangle Bar Types

Industrial Tube & Steel carries a vast inventory of ductile iron rectangular bar to suit any application. This material is produced to meet ASTM A536 specification standards, and is available in the following grades:

  • 65-45-12
  • 80-55-06
  • 100-70-03
  • Solution Strengthen Ductile Iron, or SSDI

65-45-12 grade ductile iron contains nodular graphite in a matrix of ferrite with small amounts of pearlite. The ferritic structure gives excellent machinability with good surface finishes along with optimal impact strengths, fatigue properties, electrical conductivity, and high magnetic permeability. This iron has approximately the same tensile and yield strengths as AISI 1020 steel in the as-rolled condition.

80-55-06 grade ductile iron contains nodular graphite in a matrix of ferrite and pearlite. The pearlite-and-ferrite structure provides higher wear resistance and strength when compared to a ferritic grade of ductile iron. This material is readily machinable and displays good surface finishes. Tensile and yield strengths are similar to AISI 1040 steel in the as-rolled condition.

100-70-03 ductile iron combines nodular graphite in a matrix of pearlite with a small amount of ferrite. It's produced in a range of sizes and shapes and is often used in place of plain carbon steel. Its machinability is similar to carbon steel.

SSDI (Solution Strengthen Ductile Iron) is a grade of ductile iron that combines the high mechanical strengths of a pearlitic ductile iron with the machinability advantages of a ferritic ductile iron. It’s an attractive grade of ductile iron for the design and manufacture of metal components.

Ductile Iron Rectangle Bar Applications

Ductile iron rectangular bar has a graphite-and-ferritic microstructure and does not cause the waste disposal problems of other materials. This characteristic helps improve part manufacturing by reducing machining time and extending tool life. Ductile iron rectangular bar is an excellent material for a variety of applications, which include:

  • Fluid power glands
  • Manifolds
  • Rams
  • Sheaves
  • Side frames
  • Slides and ways
  • Cylinder liners
  • Shock-absorbing pistons
  • Valve guards 

While ductile iron rectangular bar exhibits toughness that’s comparable to low to medium plain carbon steels, it’s also a more cost-effective option. This blend of performance and affordability makes ductile iron rectangular bar ideal for use in an assortment of industries including oil & gas, fluid handling and machinery.
