(a) True

(b) False

I had been asked this question during an internship interview.

My question comes from Steel and Iron Work in section Rules and Methods of Measurement of Civil Engineering Drawing

Answer 1

The correct option is (a) True

For explanation: ‘Stainless’ is a term coined early in the development of these steels for cutlery applications. It was adopted as a generic name for these steels and now covers a wide range of steel types and grades for corrosion or oxidation resistant applications.

Stainless steels are iron alloys with a minimum of 10.5% chromium. Other alloying elements are added to enhance their structure and properties such as formability, strength and cryogenic toughness.
