Literature. When tensile testing gray iron castings specified by ASTM A48, most customers use machined specimens. These specimens are often referred to as a "dumbbell", "dogbone" or "button-end" specimens. They have shouldered ends that are used for gripping the specimen during testing. ASTM A48/A48M :Standard Specification for Gray Iron Dec 01, 2003 · ASTM A48/A48M, 2003 Edition, December 1, 2003 - Standard Specification for Gray Iron Castings. This specification covers gray iron castings intended for general engineering use where tensile strength is a major consideration. Castings are classified on the basis of the tensile strength of the iron in separately cast test bars.

Dec 09, 2020 · Its Standard ASTM A48/A48M gives the standard specifications for gray iron castings. ASTM A48/A48M categorizes gray iron into classes according to its minimum tensile strength in thousands of pounds per square inch (KSI) as follows. ASTM Class 20 gray Iron has a minimum tensile strength of 20 ksi (140 MPa). Engineering American Cast Iron Products, Inc.Gray Iron Specifications. 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). Equivalent grades of gray iron, ductile iron, sg iron Standard.

Gray Iron in ASTM A48 Gray Iron castings in ASMT A48 are intended for general engineering use where tensile strength is a major consideration. Its different use against to ASMT A126 or ASTM A278. . ww.castingquality Reference Casting Standards:ASTM A48-03 Standard Specification for Gray Iron Castings The Differences Between Ductile Iron and Gray Iron CastingsJun 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). What is Gray Iron - Gray Cast Iron - Definition Material 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.
