PREN =% Cr + ( % Mo x 3,3 ) + ( % N x 16 )
PREN is a guideline formula for calculating the properties of stainless steel and there risist against pitting. You could say that the content of Molybdenum, has 3.3 times as great effect against corrosion, as the content of chrome, and Nitrogens has 16 times. To ensure the right quality of stainless steel, Blue Wave has invested in an X-ray gun for the control of raw materials, to ensure that customers always get the desired quality. Below is a table of the most frequently used types of stainless steel at Blue Wave.
