Oxidation of the casting skin is common for low carbonequivalent cast irons and for most low-carbon steels. It is likely that the majority of the oxidation is the result of reaction with water vapour from the mould, and not from air which is expelled at an early stage of mould filling as shown earlier.
Carbon Equivalent and Multiplying Factor for Hardenability of Steel The correlation of the carbon equivalent and the multiplying factors are clarified by a heat conduction analysis BY T. KASUYA AND N. YURIOKA ABSTRACT. The carbon equivalent and the multiplying factor are indexes for hardenability of steels. The carbon

Carbon dioxide equivalent (CO2e) Carbon dioxide equivalent or CO2e is a term for describing different greenhouse gases in a common unit. For any quantity and type of greenhouse gas, CO2e signifies the amount of CO2 which would have the equivalent global warming impact.
Jul 11, 2016 · With the carbon equivalent number, properties of the metal such as application suitability can be determined. Why is Carbon Equivalent Important? Knowing the carbon equivalent, or CE value, is particularly important in situations in which two pieces of metal will be welded together, such as welding two pipes together.

a carbon equivalent equation that could cover a wide range of carbon contents for cold-cracking assessment. They reviewed the works of Beckert , Stout  and Sayffarth  to integrate all non-linear contributions and developed new equations for carbon equivalent and maximum hardness for steels with a carbon content between 0.01 and 0.30% :
Nov 28, 2017 · The equation for calculating the carbon equivalent for ASTM A615 reinforcing steel is: CE = %C + (%Mn)/6 %C and %Mn are listed on every mill certificate, and the carbon equivalent should be calculated for every mill certificate. Sometimes, the carbon equivalent may even be calculated on the mill certificate for you.
