Calculate the weight of different steel forms With our steel-weight-calculators you can calculate the weight of steel round material, tubes as well as squares.
Calculation of the carbon equivalent (CEV). CEV stands for "Carbon equivalent value", which means carbon equivalent in German. With this tool you can calculate the CEV value. A maximum of three digits after the decimal point are required for this. The formula used by the International Institute of Welding is only recommended from a carbon content of 0.18 percent.
Calculation of PREN. The PREN index (Pitting Resistance Equivalent Number) is a measure of the corrosion resistance of a stainless steel. The ASTM G48 specifies the detailed test methods. In general, the higher the PREN value, the more corrosion-resistant the steel.
