Aug 07, 2007 · Ductile Iron. Ductile iron was first patented in 1949 after foundrymen searched for the ideal cast iron, which was easy to cast like gray cast iron, but had properties equal to or better than malleable iron. Ductile irons are in fact a family of cast irons characterized by Difference Between Ductile Iron & Malleable Iron HunkerProperties. Metal workers can draw out a 2-inch test sample of ductile iron by 18 to 30 percent more than its original length. By contrast, malleable iron elongates by only 10 percent. Ductile iron has a higher "yield strength" than malleable iron, meaning it can bear greater loads and higher temperatures. However, according to the Kirkpatrick

ASTM A 536 is the most frequently used, covering the general engineering grades of Ductile Iron. The other standards cover austenitic and special Ductile Iron applications. The ASTM has issued in 1990 a new specification defining the properties of Austempered Ductile Iron. Ductile Iron Data - Section 3 - Part 2The low stress behaviours of Gray Iron, Ductile Iron and mild steel, see Figure 3.3, indicate their relative damping capacities. Gray Iron, which exhibits non-elastic behaviour at very low stresses, has the highest damping capacity, while steel, which behaves elastically up
1. Equivalent Material Grades of Ductile Iron GJS-450 The equivalent grades of EN 1563 EN-GJS-450-10 are ASTM A536 65-45-12, FCD400, FGS400 60-42-10, QT450-10, ISO 450-10. Although some grades just require elongation 10%, the iron foundries just n chemical composition to make the elongation a little higher, then they will meet the requirement. 2. EN-GJS-600-3 - Grade 600-3 Ductile Iron (SG)Grade 600-3 SG iron supplied in bars up to 3m in length, stock can be cut to length as required. The final number in the SG iron grade (EN-GJS-600-3) refers to the minimum percentage elongation. Our EN-GJS-600-3 SG iron (ductile iron) is supplied conforming to BS EN

Gray Iron Overview. Dura-Bar continuous cast gray irons contain flake graphite in matrix structures that range from all pearlite to pearlite plus ferrite depending on the grades. The flake configuration corresponds to ASTM Type VII and is available in Type D, size 6-8 or Type A, size 4-6. Malleable vs. Ductile Iron - A Comparison of Malleable and
- Iron HistoryMalleable vs. Ductile Iron PropertiesUses For Malleable IronUses For Ductile IronGrade 700-2 SG Iron bar - EN-GJS-700-2EN-GJS-700-2 is a grade of ductile iron or SG iron, so called because the graphite forms nodules or spheres - Spheroidal Graphite. The rounded graphite nodules produces a more ductile cast iron compared to grey iron which contains graphite in flake form. The graphite spheres inhibits the propagation of cracks.
Strengthened ferritic spheroidal graphite cast iron grades (SSFDI) ductile iron that contains significantly more silicon than conventional ductile iron grades. Effect of better mechanical properties are by fact that Fe atoms are substituted by smaller Si atoms as a result higher yield strength and at the same time noticeably improved results in elongination.

Equivalent Grades of Ductile Iron (SG Iron, Nodular Graphite Iron) ISO. ISO 1083. The Difference between Ductile Iron and Gray Iron Gray irons tensile strength ranges from 20,000 psi 60,000 psi, whereas ductile irons ranges from 65,000 psi 80,000 psi and can be heat treated to 100,000 psi. Ductile iron has lower thermal conductivity, so it can insulate better than gray iron. Ductile iron is
Jun 18, 2015 · There are many grades of gray iron as per the ASTM A48 standard. While gray iron does not have a measurable yield strength, the range for tensile strength is 20,000 psi 60,000 psi. Impact Ductile iron has a greater resistance to impacts, and is able to resist a minimum of 7 foot pounds of impact (versus 2 pounds of impact for gray iron).
