Factors Affecting the Crevice Corrosion Susceptibility of ride containing environments. However, Alloy 22 may be prone to crevice corrosion in certain condi-tions. There are many factors or variables that influence the susceptibility (or resistance) of Alloy 22 to crevice corrosion. They can be classified into environmental or external factors and metallurgical or internal factors. External factors The influence of metallurgical factors on corrosion The targeted dominant metallurgical factors focussed upon are chemical compositions, heat treatment, manufacturing process and microstructures.The emphasis is placed upon effect of Molybdenum content on corrosion fatigue strength of austenitic stainless steels in 3%NaCl aqueous solution, tempering temperature on corrosion fatigue strength of 13 Fundamentals of Corrosionof corrosion experienced is proportional to the electro­ lyte's ability to react, the potential difference between anode and cathode, and the amount of resistance in the external metal circuit" (t p. 4).
