Cast iron tubing and cast iron pipe are preferred for machinability, sliding wear resistance, heat treat response, noise and vibration damping characteristics. This makes cast iron ideal for many industrial applications, including pulleys, gears, wheels, and pistons. Alro Steel gray cast iron has superior mechanical versatility and strength because of its shape and internal graphite distribution. In addition to its renowned mechanical capabilities, gray cast iron is an ideal metal for the budget conscious, due to its cost-effectiveness, low scrap output, and the little downtime it produces through rarely needed tooling changes.
Cast iron is a ferrous alloys which has been heated until it liquefies, and is then poured into a mold to solidify. It is usually made from pig iron. Alro Steel is a proud distributor of Dura-Bar cast iron products.
Dura-Bar 65-45-12 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. This specification conforms to ASTM A536 grade 65-45-12.
Dura-Bar 80-55-06 ductile iron will contain nodular graphite in a matrix of ferrite and pearlite. The pearlite/ferrite structure provides higher wear resistance and strength when compared to a ferrite grade of ductile iron. This material is readily machinable with good surface finishes. Tensile and yield strengths are similar to AISI1040 steel in the as-rolled condition. This specification is similar to ASTM A536 grade 80-55-06.
Dura-Bar G2 is a pearlitic gray iron containing Type A graphite. Gray Iron bars made to this specification have optimal strength, wear and hardness when compared to the other gray iron grades. This material is well suited for applications requiring high resistance to wear and response to heat treatment. This specification is similar to ASTM A48 class 40.
