G2 Gray Iron - Dura-Bar

G2 Gray Iron. Dura-Bar G2 is a pearlitic gray iron containing Type A graphite. Our continuous cast bars made to this robust specification are a good fit for a variety of applications, due to its good machinability, wear resistance and vibration damping properties. Gray Iron Iron Casting Research Institute, Inc.Sep 07, 1990 · The variable relation between Brinell hardness and tensile strength for gray iron is confusing to materials engineers, who are accustomed to the fixed relation of Brinell hardness to tensile strength for wrought steel of about 492. For gray iron, the ratio will vary from as low as 140 for low-strength irons to over 250 for gray irons having a tensile strength of over 60,000 psi.

Machinability Rating [%] = (Score of a material / Score of SAE1112) * 100 (So SAE1112gets a score of 100%) The score typically factors results of several different tests:1. Cutting Speed Test:The cutting speed in which the cutting tool can survive for 60 minutes machining the material. 2. Tool-Life Test:In this test, we measure how long it takes to reach specified wear on the cutting tool at certain cutChapter 3:Machinability of Metals Cutting Tool Dec 28, 2009 · Metal Machining The term "machinability" is a relative measure of how easily a material can be machined when compared to 160 Brinell AISI B 1112 free machining low carbon steel. The American Iron and Steel Institute (AISI) ran turning tests of this material at 180 surface feet and compared their results for B 1112 against several other materials. Materials - Steel - Carbon, Alloy, Grades G.L. Huyett1045 This medium-carbon steel is stronger than 1018 and is more difficult to machine and weld. Max. attainable Rockwell hardness is B90. Melting point is 2800° F. Yield strength is 77,000 psi. Melting point is 2800° F. Yield strength is 77,000 psi. Rockwell Hardness Guide What it is, How to Measure, & MoreIt depends entirely on a blades intended use as to what hardness knife makers specify for their steel. As a rule of thumb, softer steels such as those rated at RC45 are more durable and withstand impact better than hard steel rated at RC60. Hard steel blades hold their edge longer than soft material.

      Steel hardness test methods and hardness conversion

      The hardness of steel is important to many processes. Steel hardness describes the properties of steel that enable it to resist plastic deformation, indentation, penetration, and scratching. In engineering, steel hardness is important because the inherent resistance of the surface to withstand friction or erosion by oil, steam, and water, typically increases with the relative hardness of steel.
