Hafiz (2001) discussed about SG iron and mechanical properties like, tensile strength, hardness, toughness .Correlations between various properties are also investigated. They also explained about Bronze vs Cast Iron - Comparison - Pros and Cons Ultimate tensile strength of martensitic white cast iron (ASTM A532 Class 1 Type A) is 350 MPa. Ultimate tensile strength of malleable cast iron ASTM A220 is 580 MPa. Ultimate tensile strength of ductile cast Iron ASTM A536 60-40-18 is 414 Mpa (>60 ksi).
The American Society for Testing Materials (ASTM) numbering system for grey cast iron is established such that the numbers corespond to the minimum tensile strength in KPSI. Thus an ASTM No. 20 cast iron has a minimum tensile strength of 20 KPSI. Note particularly that the tabulations are typical values. Multiply strength in KPSI by 6.89 to get Cast Iron Types Metal Casting ResourcesJul 13, 2021 · A few common mechanical properties for cast iron include:Hardness materials resistance to abrasion and indentation; Toughness materials ability to absorb energy; Ductility materials ability to deform without fracture; Elasticity materials ability to return to its original dimensions after it has been deformed Cast Iron vs Cast Steel Metal Casting BlogAug 04, 2021 · Cast iron typically contains more than 2 percent carbon, while cast steel often contains between 0.10.5 percent carbon. Characteristics. The following table provides a general overview of the qualities of each material. While there are many different types of iron and steel to consider, this table focuses on grey iron, cast iron, and carbon
casting has higher rate of cooling than the thicker section [6-7]. Hardness and ultimate tensile strength are the most commonly specified properties for iron castings. Hardness is a relatively good indication of machinability; however, gray and ductile iron with the same hardness can exhibit Gray Iron Iron Casting Research Institute, Inc.Sep 07, 1990 · By suitable adjustment in composition and selection of casting method, tensile strength can be varied from less than 20,000 psi to over 60,000 psi and hardness from 100 to 300 BHN Grey Cast Iron FG 300/GG30 Material Custom Casting While grey cast iron has less tensile strength and shock resistance than most other castings or even steal, it has compressive strength that is comparable to low- and medium-carbon steel. These mechanical properties are controlled by the size and shape
Hardening and tempering of grey iron aims to improve the mechanical properties such as hardness, wear-resistance (increases five times of cast-state), and some tensile strength, hi hardening, the castings are heated to a high temperature of about 850°-885°C (around 95°C above the calculated A 1 transformation temperature from equation 15.2 Iron (Fe) - Properties, ApplicationsJul 11, 2013 · Tensile strength at break:540 MPa:78300 psi:Yield strength:50 MPa:7250 psi:Poissons ratio:0.291:0.291:Modulus of elasticity:200 GPa:29000 ksi:Shear modulus:77.5 GPa:11200 ksi:Hardness, Brinell:146:146:Hardness, Vickers:150:150:Hardness, Rockwell A:49:49:Hardness, Rockwell B:79:79 Relation between the Hardness and the Strength of Gray Mar 01, 2018 · The factors that affect the relation between ultimate tensile strength u and hardness HB of gray cast iron with flaked graphite are studied. The scatter of the ultimate tensile strengths at a given hardness is shown to be caused by one of the primary structure parameters, namely, the volume fraction of primary austenite dendritic crystals. The dependences derived in this work can be used to
either as-cast or by heat treatment. Ductile iron, that is heat treated by quenching to martensite and tempering, may have substantially lower fatigue strength than as cast material of the same hardness. 6. Test Coupons 6.1 The separately cast test coupons from which the tension test specimens are machined shall be cast to the size and shape Tensile strength and hardness of sub-zero chilled cast ironJan 01, 1995 · Abstract. This paper describes the results obtained and the deductions made from a series of ultimate tensile strength (UTS) and hardness tests performed on sub-zero chilled (using liquid nitrogen) cast iron containing 1.5% Cu, and of chromium contents ranging from 0.0% to 0.2%. By using copper chills of different thicknesses, the effect on UTS grey cast iron composition - Sand Casting, Investment and 0.3-5% silicon plus manganese, sulphur and phosphorus. It is brittle with low tensile strength, but is easy to cast. The all data in this documents is referred to Chinese standard of GB/T 9439-1988.
