Question 64

Stainless steels have higher coefficients of thermal expansion than carbon steel or low alloy steel or nickel based alloys and are more likely to see _________.

    Correct Answer: B

    Stainless steels have higher coefficients of thermal expansion compared to carbon steel, low alloy steel, and nickel-based alloys. This means that when exposed to temperature changes, they will expand and contract more than these other materials. This greater expansion and contraction can lead to higher mechanical stresses within the stainless steel, especially if the temperature changes are rapid or uneven, potentially leading to thermal fatigue or other stress-related issues.

Discussion
ahmadmmOption: B

Critical Factors of Thermal Shock - The magnitude of the temperature differential and the coefficient of thermal expansion of the material determine the magnitude of the stress. - Stainless steels have higher coefficients of thermal expansion than carbon and alloy steels or nickel-based alloys and are more likely to see higher stresses.
