What is 65-45-12 ductile iron?
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.
What is ductile iron made of?
How is Ductile Iron Made? Rather than being cast from iron or steel scrap, ductile iron is made primarily from the crude iron that’s produced by smelting ore in a blast furnace, commonly called ‘pig iron. ‘ Pig iron is about 90% iron with high carbon content, and its chemical properties are very stable.
What is ASTM D2000?
ASTM D2000 is an industry specification that provides buyers and suppliers with a standard way to describe rubber. Published by ASTM International and designed for automotive applications, this classification system is used by many other industries because it’s clear, concise, and highly descriptive.
Is ductile iron stronger than steel?
While there is no large difference when it comes to tensile strength, ductile iron has the greater yield strength (40 ksi). Cast steel, on the other hand, can only reach 36 ksi yield strength. As the strength of ductile iron increases ductility decreases. Ductile iron has superior shock absorption to steel.
What is SG casting?
SG Iron is also known as Ductile Cast Iron, Nodular Cast Iron, Spheroidal Graphite Iron and Spherulitic Cast Iron. This grade of Iron was developed over 60 years ago and in the USA. In SG Cast Iron the graphite is in the form of spherical nodules (hence the name Spheroidal Graphite) rather than flakes as in Grey Iron.
Is steel a ductile material?
In general, soft tough metals will be ductile. Harder, stronger metals tend to be more brittle. The relationship between strength and hardness is a good way to predict behavior. Mild steel (AISI 1020) is soft and ductile; bearing steel, on the other hand, is strong but very brittle.
What is ferritic ductile iron?
Ferritic Ductile Iron Graphite spheroids in a matrix of ferrite provides an iron with good ductility and impact resistance and with a tensile and yield strength equivalent to a low carbon steel.
How do you read ASTM?
Every ASTM standard is identified by a unique designation. It includes a capital letter (A – H), followed by a serial number ranging from one to four digits, a dash, and finally the year of issue.
What is NBR seal material?
Nitrile rubber (NBR) is the general term for Acrylonitrile Butadiene Copolymer. It is the most widely used and economical elastomer. NBR offers excellent resistance to petroleum-based oils and fuels, silicone greases, hydraulic fluids, water and alcohols.
Which is a grade of ductile iron ASTM A536?
Ductile Iron ASTM A536. ASTM A536 65-45-12 is a nodular Iron with a ferritic and pearlitic microstructure and mechanical properties comparable to low alloy steels. Ductile iron 65-45-12 is one grade in a family of many. Chemistry requirements are not specified in the ASTM A536 standard.
What is the chemical composition of ASTM A536 80-55-06?
Chemical Composition, Mechanical and Physical Properties. ASTM A536 80-55-06 is a special ductile cast iron grade. It has comparatively high tensile strength, and also high elongation, so its is a good cast iron material.
What kind of steel is ASTM 65-45-12?
ASTM A536 65-45-12 is a nodular Iron with a ferritic and pearlitic microstructure and mechanical properties comparable to low alloy steels. Ductile iron 65-45-12 is one grade in a family of many. Chemistry requirements are not specified in the ASTM A536 standard. Chemistry and hardness listed in this spec would be typical for a Grade 65-45-12.
