Its mechanical properties – strength, wear resistance, fatigue strength, toughness and ductility - are competitive with many cast, forged, and fabricated steel products, yet the result, in most cases, is lower cost and better looking parts.ĭuctile iron’s ease of maching and economy of production are almost equal to gray iron. This ensures the end user that production lead-times are reasonable and that a variety of suppliers are capable of producing their product.ĭuctile iron, a family of versatile cast irons, offers the design engineer versatility. Unlike cast steel, ductile iron capacity in North America is abundant.4.Ductile iron castings are readily available:.Its high yield strength and ductility make it an economical choice for many applications. It is considerably less expensive than cast steel and only moderately more expensive than gray iron. Its wear resistance is comparable to some of the best grades of steel and superior to gray iron in heavy load or impact load situations. The improved mechanical properties of ductile iron increase its resistance to breakage from physical load, or mechanical and thermal shock far above that of gray iron.Ductile iron castings outperform cast steels and gray iron in many applications: It has the ability to contract and develop 1,500 new products annually. With 30 years of precision casting experience, more than 20,000 products and more than 900 alloy grades have been developed. When heat treated ductile iron’s design flexibility can be enhanced to an even greater degree. Pintejin has a technical team of 100 people, focusing on the precision casting process. Several grades can be used in the as-cast condition without additional heat treatments. Casting, steel (20) Iron, special grade and pig iron (20) Stoves, cast iron (14) Iron and steel industry and foundries - machinery and installations (13) Moulds, foundry (10) White malleable cast iron (10) Radiators, cast iron (9) Casting of special and high-grade steels (7) Pipes and tubes, cast iron (7) Foundries, aluminium (5) Iron alloys (5.
Ductile iron is less brittle than most types of iron. Ductile iron castings are a cost effective substitute for carbon and low alloy steels, and in some applications, ductile iron can even outperform steel.Ductile iron is one of the most ductile of all cast irons and shows 18% to 30% elongation on a test piece.This is higher than grades 70-36 and 60-30 cast steel or ordinary gray iron (which has no true yield strength) The yield strength of A395 ductile iron is a minimum of 40,000 psi.The as-cast tensile strength of ductile iron ranges from 60,000 to 100,000 psi The tensile strength of ductile iron begins where gray iron stops. Iron Casting Foundry Total 912 manufacturers & suppliers found with 2,736 products Supplier List Online Trading Baoding Worth Engineering Technology Co., Ltd.The ductile iron family offers the designer and engineer a unique combination of strength, wear resistance, fatigue resistance, and toughness, as well as excellent ductility characteristics.Ductile iron castings offer a wide range of mechanical properties:
