Such oxidizing media include both nitric and chromic acids. Presence of this element can improve resistance to reducing acids and caustic and resistance to stress corrosion cracking.Īlloying with Cr improves resistance to higher temperature oxidizing and sulfidation and resistance to oxidizing environments in general. Improves high temperature strength, resistance to oxidation, nitridation, carburization and halogenation. Understanding the elements and both positive and negative effects on the alloys can help to identify what applications certain alloys can be used in. While chromium, nickel, molybdenum, iron may be the primary alloying elements, other elements like tungsten, carbon, aluminum, titanium, copper and sulfur can have significant effects as well. The different elements that make up an alloy can drastically change the mechanical properties, corrosion resistance and the metal’s microstructure.
