Question

Why is it not practical to use stainless steel to build structures such as bridges that are prone to corrosion?

Question 11 options:

stainless steel will corrode quickly if the protective coating is broken

the chromium used in stainless is too expensive

stainless steel is not strong enough

the carbon used to make stainless steel is too expensive

Answer 1

While bridges have relied on general carbon steel for close to 150 years, stainless steel, because of its relative expensiveness, was generally used only for support materials. In particular, it was valued for its anti-corrosion properties and used in safety features such as guardrails and handrails
