The effect of CO2 shielding on the carbon content of mild, low-alloy steel and stainless steel weld metal is unique (as also referred earlier). Depending on the original carbon content of the base metal and the electrode, the CO2 atmosphere can behave either as a carburizing or decarburizing medium. Whether the

steel - steel - Casting of steel: The simplest way to solidify liquid steel is to pour it into heavy, thick-walled iron ingot molds, which stand on stout iron plates called stools. During and after pouring, the walls and bottom of the mold extract heat from the melt, and a solid shell forms, growing approximately with the square root of time multiplied by a constant.
The Prandtl Number - Pr - is a dimensionless number approximating the ratio of momentum diffusivity (kinematic viscosity) to thermal diffusivity - and is often used in heat transfer and free and forced convection calculations.. The Prandtl number can for calculations be expressed as. Pr = μ C p / k (1). where μ = absolute or dynamic viscosity (kg/m s, lb m /(ft h))
