ASTM Specification A-536

V-3 (65-45-12) ductile iron has a tensile strength of 65,000 psi with a yield strength of 45,000 psi and 12% elongation. 65-45-12 ductile iron hardness ranges from 131 to 220 bhn. The microstructure as cast is ferritic. The fine ferritic structure makes V-3 65-45-12 ductile iron the easiest machining of the three grades of Versa-Bar.

V-3 ductile iron offers high spindle speeds, less tool wear and better finishes. It’s widely used to pistons in the hydraulics industry. 65-45-12 grade ductile iron provides excellent wear resistance and high strength in metal-to-metal applications.

V-3 Continuous Cast SG Ductile Iron is a Fine Steel Replacement

When compared directly 1144 steel (including material cost) our machining tests showed the V-3 ductile iron cost up to 20% less to produce the same part. All grades of continuous cast iron from American Iron & Alloys offer you tremendous cost savings. Versa-Bar ductile iron is an excellent, more affordable alternative to steel, and contains several benefits for producing:

  • Sprockets
  • Gears
  • Pulleys
  • Spindle housings
  • Flywheels
  • Pistons

Versa-Bar 65-45-12 Ductile Iron Boasts Greater Durability and Longer Life

65-45-12 ductile iron

V-3 65-45-12 ductile iron features unparalleled machinability.

Versa-Bar ductile iron offers you unprecedented machinability and performance. Versa-Bar’s continuous casting process provides uniformity and consistent soundness you’ll never achieve by sand casting. Turning speeds of 30% or more means increased tool life and decreased labor expense.

High graphite flake content in ASTM A536 SG Versa-Bar means every bar contains tiny recesses retaining oil—lubricated parts stay oily for longer. Well dispersed and retained lubricant means a part made of Versa-Bar has a much better chance of survival should there be oil loss.

Versa-Bar is the true hydraulic metal. Its natural non-abrasive quality gives it extremely high wearability. Versa-Bar represents an opportunity you can’t afford to pass up.

V-3 65-45-12 ductile cast iron beats aluminum, bronze and steel in basic field comparison testing.

Operators were asked to reach the best surface feed per minute (sfm) on 65-45-12 Versa-Bar ductile cast iron and maintain comparable depth of cut and surface roughness with aluminum, bronze and steel grades.

Machine used: a 7hp lathe set up for production of hydraulic cylinder pistons. The cutting tools used in the analysis: a Valenite VC 67 Carbide Insert.

Here are the results:
