Gray Iron bars made to this specification have optimal strength, wear and hardness when compared to the other gray iron grades. This material is well suited for applications requiring high resistance to wear and response to heat treatment. This specification is similar to ASTM A48 class 40.
Jul 13, 2021 · ASTM A48 Class 20 (Related Standards ISO 185/JL/150, SAE J431, EN-GJL-150) is a gray cast iron. Gray iron has a long history, and is one of the most widely used metallic materials. This is due to its low cost, ease of production, and unique, beneficial characteristics. Gray Iron Class 40 Products ::Atlas BronzeIt is a pearlitic gray iron containing Type A graphite. Gray Iron bars made to this specification have optimal strength, wear and hardness when compared to the other gray iron grades. This material is well suited for applications requiring high resistance to wear and response to heat treatment. This specification is similar to ASTM A48 class 40. Gray Iron Gray Iron Grade Comparison Dura-BarDura-Bar G2 gray iron will contain this type of graphite distribution and will be best suited for applications requiring moderate strength, good vibration damping and thermal conductivity, along with optimal machining characteristics. Dura-Bar G2 is built around ASTM A48 Class 40 gray iron.
Feb 17, 2020 · What means of ASTM A48 Class 30B? Each class is designated by a number followed by a letter in ASTM A48 standard. The number indicate the minimum tensile strength of the separately cast test bar, and the letter indicates the size of the test bar. 30 Texcellent Cast IronASTM A48; Mechanical Properties Class 30 Hardness:175 HB Typical:Tensile:30 ksi min:Mechanical Properties Class 40 Hardness:180 HB Typical:Tensile:40 ksi min:Cast Iron (ASTM A48) Cast iron (gray iron) is an alloy of iron and carbon. The high carbon content yields a flake graphite structure. Cast iron is popular due to the good strength What are Properties of Gray Cast Iron - Definition Youngs modulus of elasticity of gray cast iron (ASTM A48 Class 40) is 124 GPa. The Youngs modulus of elasticity is the elastic modulus for tensile and compressive stress in the linear elasticity regime of a uniaxial deformation and is usually assessed by tensile tests. Up to a limiting stress, a body will be able to recover its dimensions on removal of the load.
Youngs modulus of elasticity of gray cast iron (ASTM A48 Class 40) is 124 GPa. 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, ASTM A 48 Class 40 - MatWebGray Cast Iron, ASTM A 48 Class 40 Categories:Metal; Ferrous Metal; Cast Iron; Gray Cast Iron.
