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. Ductile iron's density of 0.256 pounds per cubic inch (lb/in³) or 7.1 grams per cubic centimeter (g/cm³) is significantly denser than aluminum but slightly less dense than steel. 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 for 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 as a steel replacement

When compared directly to 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 Lawton Standard offer tremendous cost savings. Versa-Bar ductile iron is an excellent, more affordable alternative to steel and contains several benefits for production:

Versa-Bar V-3 65-45-12 ductile iron for greater durability and longer life

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 the comparable cut and surface roughness depth with aluminum, bronze, and steel grades.

Machine used: A 7hp lathe was set up to produce hydraulic cylinder pistons. The cutting tools used in the analysis: a Valenite VC 67 Carbide Insert.

Here are the results:

The results, reached through conventional tooling and equipment, demonstrate Versa-Bar's competitive superiority.
