Continuous Cast Gray and Ductile Iron
Alternative to Steel and Sand Cast Iron

Continuous cast gray and ductile iron is the most metallurgically superior steel alternative on the market. Fluid power and bearing manufacturing industries are switching to our continuous cast iron because it is much more cost-effective than any other steel alternative.
The continuous cast process ensures the iron solidifies at a more uniform rate, so the iron is more durable and reliable than traditional sand cast iron. Bar is manufactured with less scrap and reduced machining, so it is not only stronger, but also costs less than sand cast iron because there are no tooling charges.
Continuous cast iron is used for a wide variety of applications including:
Hydraulics: Pistons, Glands, Manifolds
Machine tool: Gears, Bushing, Pulleys,
Patterns, Mould, Mounting Plates, Pins
Brake Disc, Bearing Caps, Valve Guides
Glass Moulds: Neck Rings, Plungers, Cores
Dies, Rollers, Sleeves, Spacers

Gray and Ductile Iron Differences
Some metallurgists will say the difference between gray and ductile iron is that ductile iron is an "upgraded" version of gray iron. But, the answer is not that simple.
Continuous cast gray iron is recommended for straight wear applications in the hydraulics industry due to its lower tensile strength, higher thermal conductivity and higher damping capacity. Gray iron is an ideal metal for bearings and bushings.

Sand Casting vs. Continuous Casting
Sand casting has been one of the most popular and simplest types of casting for centuries. It relies on silica-based materials, typically synthetic or naturally-bonded sand to form a mold. Sand casting is inexpensive and can be used for both ferrous and non-ferrous metals. However, sand casting tends to yield a lower degree of accuracy and a rougher surface finish when compared to continuous casting.
Continuous casting is a refined process for continuous, large volume production. Continuous casting is also known as strand casting, and produces high quality products in a variety of shapes and sizes including square bars, tubes, hexagonal profiles and slabs with varying thickness levels.

ASTM A536 - 84(2014) 
Standard Specification for Ductile Iron Castings
This specification covers ductile iron castings, also known as spheroidal or nodular iron, that is described as cast iron with the graphite substantially spheroidal in shape and essentially free of other forms of graphite. Appropriate heat treatment shall be identified according to grades, as follows: a full ferritizing anneal for 60-40-18; a quench and temper, or normalize and temper, or isothermal heat treatment for 100-70-03 and 120-90-02; and as-cast for 65-45-12 and 80-55-06. Castings shall be tested and conform to specified tensile requirements such as tensile strength, yield strength, and elongation. When indicated in the contract or purchase order, castings shall also adhere to special requirements like hardness, chemical composition, microstructure, pressure tightness, radiographic soundness, magnetic particle inspection dimensions, and surface finish.
This specification covers castings made of ductile iron, also known as spheroidal or nodular iron, that is described as cast iron with the graphite substantially spheroidal in shape and essentially free of other forms of graphite, as defined in Terminology A644.
No precise quantitative relationship can be stated between the properties of the iron in various locations of the same casting or between the properties of castings and those of a test specimen cast from the same iron (see Appendix X1).

ASTM A48 / A48M - 03(2012) 
Standard Specification for Gray Iron Castings
This specification covers gray iron castings intended for general engineering use where tensile strength is a major consideration. Castings are classified on the basis of the tensile strength of the iron in separately cast test bars. The surface of the casting shall be free of adhering sand, scale, cracks, and hot tears, as determined by visual examination. The test bars are designated into S, A, B, and C categories, according to the thickness of its controlling wall section. The casting shall be subjected to a tension test to determine its tensile strength.
This specification covers gray iron castings intended for general engineering use where tensile strength is a major consideration. Castings are classified on the basis of the tensile strength of the iron in separately cast test bars.
This specification subordinates chemical composition to tensile strength.
Castings produced to this specification are graded on the basis of minimum tensile strength obtained in special test coupons designed to standardize cooling rate. The tensile strength developed in certain casting sections may vary from test coupon values
