For example, Mo gives the steel higher working temperatures and added strength.See all results for this questionsp.info What are the two key alloying elements?As the name suggests, the two key alloying elements are molybdenum (Mo) and chromium (Cr). These alloys are normally sorted into one main group, with names such as chrome croalloy, chromalloy, moly and CrMo often used [1]. Industries where the alloy is common include construction, energy, oil and gas, and automotive.See all results for this questionsp.info Does increasing the Mo content of steel increase creep ductility?However, continually increasing the Mo content of the steel in order to further improve its properties does not work since creep ductility actually decreases with increasing Mo [2]. Another limitation refers to the fact that graphitization (breaking down of iron carbides) takes place above 500 °C.See all results for this question

What is the advantage of CR in steel?

Moreover, the Cr results in exceptional oxidation, and helps the steel resist corrosion in a more effective manner [1]. The Cr also provides good hardness penetration, and the Mo content guarantees the hardness is uniform [3].See all results for this questionsp.info Alloy design employing high Cr concentrations for Mo-free ...3 rows · Aug 01, 2018 · Material and methods.
