It is a product between grey cast iron and white cast iron in composition, colour and properties. It is obtained in casting where certain wearing surfaces have been chilled. Malleable Cast Iron. The malleable cast iron is obtained from white cast iron by a suitable heat treatment process (i.e., annealing). The annealing

Benton Foundry, Inc. Gray Iron Castings - Benton Foundry

Class 25,30,35,40 tensile and heat resistant irons. Gray Iron has a dense gray structure and offers excellent machinability. Grades 25, 30, 35 and 40 can fill specific requirements for hardness and wear, and heat treatments can yield even higher mechanical properties. Popular applications for gray iron include diesel and gasoline engine blocks and cylinder liners, [] Cast Iron Grades Table for Grey Iron, Malleable Iron, and Cast iron material grade comparison and equivalent grades for grey iron, malleable iron and nodular iron. Class 40 Gray Iron Supplier Material Properties Our V-2 Class 40 Continuous Cast Gray Iron is a Better Alternative. V-2 (Class 40) gray iron features a tensile strength of 40,000 psi with a compression strength of 150,000 psi. Class 40 gray irons hardness ranges from 187 to 269 bhn. The microstructure is essentially pearlitic.

Difference Between Grey Cast Iron and White Cast Iron

Dec 11, 2015 · What is Grey Cast Iron? The most commonly used category of casting alloy is grey cast iron. The composition includes about 2.5% to 4% carbon and 1% to 3% silicon.In the process of making grey cast iron, the proper control of carbon and silicon content and maintaining the proper cooling rate prevents the formation of iron carbide during solidification.This helps to precipitate graphite directly Grey Cast Iron EN-JL1040 and EN-GJL-250Grey Cast Iron EN-JL1040 and EN-GJL-250 :These are the chemical composition, mechanical properties and equivalent grades of cast iron EN-JL1040 (EN-GJL-250), including its Tensile Strength, Elongation, Proof strength and Hardness. Grey cast iron ASTM 40 [SubsTech]Jun 02, 2012 · Grey cast iron ASTM 40:Chemical composition:C=2.7-4%, Mn=0.8%, Si=1.8-3%, S=0.07% max, P=0.2% max Property:Value in metric unit:Value in US unit:Density :7.06 *10³-7.34 *10³ :kg/m³ :441-458 :lb/ft³ :Modulus of elasticity

Properties:An Introduction to Grey Iron

These are a form of cast iron that have variable properties dependent on the microstructure. The microstructure can be altered via heat treatments. In general these materials have low tensile strengths but good compressive strengths, hardness, corrosion resistance and wear resistance.

The Differences Between Ductile Iron and Gray Iron 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).

V-1 Class 30 Gray Iron Supplier Properties, Composition Contact cast iron suppliers at American Iron & Alloys for a quote on iron stock or custom cast parts. Class 30 gray iron (30,000 psi) is used for many types of custom cast parts. The high damping capacity of Versa-Bar V-1 gray iron (about 20 to 25 times higher than steel), along with its high hardness and machinability make it well suited for What are Properties of Gray Cast Iron - Definition Gray Iron Gray Cast Iron. Gray cast iron has less tensile strength and shock resistance than steel, but its compressive strength is comparable to low- and medium-carbon steel. Gray cast iron has good thermal conductivity and specific heat capacity, therefore it is often used in cookware and brake rotors.. Gray cast iron have also an excellent damping capacity, which is given by the

Gray Iron ASTM A48 Class 30 Data Sheet Penticton Foundry

Sep 12, 2018 · ASTM A48 Class 30 (Related Standards DIN GG20, BS 1452 Grade 220) is a gray cast iron. Gray iron consists of graphite flakes in a metallic matrix. When fractured, it is grayish in colour hence the name (specifically, a fracture will follow along the graphite flakes which are gray).
