Ductile IronHardening Treatment : Hardening treatment toductile ironcould increase the surface hardness ofcastings, to make thecastingwith good hardness and abrasive resistance.. The normal quenching and tempering treatment could increase the surface hardness to about HRC 30 to HRC 40 of Rockwell Hardness, thisprocessincludes the heat heated to 880-930 centigrade, then quenching in …

Ductile Iron CastingsFrom ounces to 3,000 pounds Inductile ironthe graphite forms into spherical nodules rather than flakes, thus inhibiting the creation of cracks and providing the enhanced ductility that gives the alloy its name.

SaguenayFoundryis an executive-owned company specialized in prototyping and short production runs of CG, gray andductile iron castingsfrom 200 to 15,000 pounds. + 1 418 545-8181 [email protected]…

In 1961, Wells Manufacturing Company introduced theprocessof continuousiron castinginto North America. Theprocesswas originally developed in Europe after World War II as an alternate method of producing castironbar stock without patterns and conventional molding methods.

The no-bake molding line at OKFoundryis most efficient for short runs of 25, 50 or 100castingsof 50 to 250 lbs. in gray orductile iron. Setups are quick on a no-bake molding line and frequent deliveries of short runcastingscan ramp production to significant volumes of lean supply.

Visitors who tour a McWaneDuctilefacility are often surprised by how much work goes into makingDuctile ironpipe.The pipe starts out as scrap metal from old cars and demolished buildings that is melted down and given a new lease on life. Up to 95% of our product is made from recycled material.

Ductile iron castingrefers to aprocessin which magnesium / cerium (as an alloy of magnesium / cerium) is added to castiron. It reacts with the sulfur and oxygen in the moltenironand changes the way the graphite is formed.Ductilecastiron(also called as spheroidal graphite castironor nodular castiron) has been widely used as a main industrial material in place of high-grade castiron.

There are two major types ofiron: wrought and cast. Within castiron, there are several different types. Learn more about their properties and uses.

Yet it isductile ironthat has become one of the most popular types ofiron casting. Development ofductile ironcontinued into the 1950s, making theprocessofductile iron castingbetter leading to acceptance ofductile iron, acceptance proven out by the nine-fold increase in use during the 1960s as an engineered material for commercial applications.

The normal quenching and tempering treatment could increase the surface hardness to about HRC 30 to HRC 40 of Rockwell Hardness, this process includes the heat heated to880-930 centigrade, then quenching in the oil, then do the tempering treatment in 500-600 centigrade.

In our blog post “Ductile IronVersus GrayIron Castings” we explore the differences betweenductile ironand grayiron, including mechanical and physical properties as well as typical applications. This particular post, on the other hand, is a generic overview ofductile iron.Ductile ironis also called spherical graphiteironor nodulariron.

To create different grades ofductile ironone must control the matrix structure around the graphite during thecasting process, or through subsequentheat treatment. There are minor compositional differences that exist between the different grades ofductile iron. These differences exist in order to create the desired matrix microstructures.
