1. Introduce
– A silvery-white metal with excellent strength and luster, which does not melt well but oxidizes easily
– Applied in plating and alloying due to its excellent corrosion resistance and strength
– Cr alloying element effect: improves strength, becomes stainless steel when added more than 10%, and improves oxidation resistance
2. Property
– Excellent corrosion resistance, strength, and magnetism
