Question 1 of 27070

Q

Stainless steel is an alloy composed mainly of __________.

🔍 Key Concepts

• Alloys are mixtures of metals designed to improve properties like strength and corrosion resistance • Stainless steel is known for its resistance to rust and staining, especially in marine environments • Think about what the word "stainless" suggests about the metal content and corrosion resistance

💭 Think About

• Which base metal is common in ordinary carbon steel, and what must be added to make it more resistant to rust? • Look at each choice and ask: if I mixed those two metals, would the result still be called a kind of steel, or would it be a different alloy name (like bronze or brass)? • In shipbuilding and marine gear, what key element is added to help metal resist corrosion from water and air?

✅ Before You Answer

• Identify the primary base metal that steel itself is made from • Recall the specific element that, when added in sufficient quantity, gives steel its corrosion-resistant, "stainless" quality • Eliminate any options that would actually form a different named alloy rather than a type of steel
