What is 80-55-06?
Grade 80-55-06 is an iron with nodular graphite in a matrix of ferrite. It also contains small amounts of pearlite. This grade has great machinability as well as good surface finishes. 80-55-06 shows high impact strengths, fatigue properties, and electrical conductivity.
Can you weld on ductile iron?
Ductile iron is more susceptible to welding stresses, and more likely to crack while welding or during cooling. Therefore, highly stressed ductile iron castings or portions thereof should never be welded. It is recommended not to perform welds if their section is more than 20% of the metal thickness.
Can you bend ductile iron?
Cast ductile iron normally contains over 3 percent carbon; it can be bent, twisted, or deformed without fracturing. Its mechanical properties are similar to steel, and far exceed those of standard cast irons.
Can you weld to ductile iron?
The weld you’re willing to do it’s impossible. Cast iron, whether ductile or gray, doesn’t accept structural welds (and this is one), but only repair welds. Generally, gears are fixed to their shafts by means of a key.
How do you tell the difference between ductile iron and cast iron?
Ductile iron can be bent without breaking, whereas cast iron is brittle and breaks when bent. As ductile iron can be bent, it can be made into different shapes and forms. But one cannot make out different shapes and forms using cast iron. While ductile iron is flexible, cast iron is not.
What kind of iron is ASTM A536 80-55-06?
ASTM A536 80-55-06 (Related standards – SAE J434C D5506; ISO 1083 500-7) is a nodular iron with a mostly pearlitic – and smaller amount of ferrite – microstructure. It has mechanical properties comparable to low alloy steels. Ductile iron 80-55-06 is one grade in a family of many. Chemistry requirements are not specified in the ASTM A536 standard.
What is the ASTM standard for ductile iron?
ASTM A536 is the American standard specification for ductile iron castings, the main material grades including: This specification covers castings made of ductile iron, also known as spheroidal or nodular cast iron, or S.G. iron.
What can I use ASTM 80-55-06 for?
Applications include: brakes, gear boxes, frames, oil and gas parts, pumping parts, compressor parts, mining parts, winch parts, wind energy and other applications. ASTM A536 80-55-06 is commonly used for municipal castings.
What kind of graphite is in Dura bar 80-55-06?
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.
