Emissivity Coefficient Materials

The emissivity coefficient - ε - indicates the radiation of heat from a 'grey body' according the Stefan-Boltzmann Law, compared with the radiation of heat from a ideal 'black body' with the emissivity coefficient ε = 1. The emissivity coefficient - ε - for some common materials can be found in the table below. Note that the emissivity coefficients for some products varies with the temperature.

The stainless steel; they contain between 10% and 20%. This makes it corrosion resistant. There are 3 types of stainless steel: Austenitic stainless steel; contain about 18% chromium, 0.8% carbon and 8% nickel. It is one of the most common and it is mainly used to die cast plumbing systems, kitchen equipment, etc.

How to Choose the Right Blast Abrasive Media

When a sufficiently hard abrasive particle strikes steel, it deforms the surface into a valley and pushes up peaks. The distance between the top of the peak and the bottom of the valley is known as the depth profile. In the U.S., the depth profile is measured by mils – thouhs of an inch.In the metric system, the micron (one-millionth of a meter) is used.
