ASTM's ferroalloy and casting standards are instrumental in classifying,evaluating,and specifying the material,chemical,mechanical,and metallurgical properties of iron alloys and their castings.The iron castings can be of the ferritic,austenitic,gray,cupola,pearlitic,ductile,or malleable types.Casting Material gray iron in ASTM A126Metal Castings Service in China castingquality [email protected] Gray Iron in ASTM A126 ASTM A126 Gray Iron casting is intended for use as valve pressure retaining parts,pipe fittings and flanges only,include three casting metal grades Class A,Class B and Class C.castingqualityClass 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.

Gray Iron.Also called grey cast iron,gray iron is a kind of cast iron with a graphitic microstructure.It has high thermal conductivity,good machinability and excellent damping capacity.Unfortunately,because of its low ductility and tensile strength,it has very little impact and shock resistance.It does,however,have good corrosion resistance because of its silicon content,which can occupy up to 6 to 10% of the content of gray iron.Gray Iron Castings - Benton Foundry,Inc.Gray Iron Castings.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,and structural
Gray Iron Castings to ASTM A48 Gray iron castings are also referred to as gray cast iron,grey iron castings,it is named after the gray color of the fracture surface.Gray Iron Gray Iron Grade Comparison Dura-BarGray 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.MATRIX IRON FOUNDRYThere are many different specifications governing the use and production of grey iron.At Matrix Iron Foundry,we produce grey iron in accordance with American Society of Testing and Materials (ASTM) A48,IS:210 1978 and BS EN 124:1994 as mentioned below.ASTM A48 covers a class of cast irons that are intended for general use applications.
Masterdrive,Inc.Standard Specification for Automotive Gray Iron CastingsAbstract.This specification covers gray iron castings for products of the automobile,truck,tractor and allied industries.The materials shall be classified into eight grades (G1800,G2500,G3000,G3500,G4000,G2500a,G3500b and G3500c) based on the range of their casting hardness,chemical composition and microstructure.What are Properties of Gray Cast Iron - Definition Properties of Gray Cast Iron ASTM A48 Class 40 The carbon and silicon contents of gray cast irons vary between 2.5 and 4.0 wt% and 1.0 and 3.0 wt%,respectively.Gray cast iron is characterised by its graphitic microstructure,which causes fractures of the material to have a gray appearance.
