• C. 18% chromium and 18 % Nickel
• D. 8% chromium and 8 % Nickel

Answer 1

Answer:

A. 18% chromium and 8% Nickel

Austenitic stainless steel contains a minimum of 16% chromium and 6% nickel. It is one of the three types of stainless steel alloys, the other two being ferritic and martensitic. Ferritic stainless steel contains chromium from 10.5 to 18%, while martensitic stainless steel has high carbon and lower chromium content. The given option 1, which states that austenitic stainless steel contains 18% chromium and 8% nickel, is the correct answer.
