Final answer:
The metal used to make stainless steel and nichrome wire is Chromium. It improves corrosion resistance and enhances the strength of stainless steel. Nichrome wire, formed by combining Chromium with nickel, has high electrical resistance to produce heat in devices like toasters.
Step-by-step explanation:
The metal used to make stainless steel and combined with nickel to form nichrome wire is Chromium. Chromium is added to stainless steel to improve its corrosion resistance and enhance its strength. Nichrome wire is known for its high electrical resistance, which allows it to generate heat in devices like toasters. Nichrome wire is commonly used in appliances like toasters and other heating devices where the generation of heat through electrical resistance is desirable.
