all of these statements are correct about ultra - high - strength steel except:
a) it is used for door intrusion beams and bumper reinforcements.
b) it is used for many structural parts.
c) it is commonly used for outer body panels.
d) its strength is destroyed by heat.

Explanation:

To solve this, we analyze each option:

• Option A: Ultra - high - strength steel is indeed used for door intrusion beams and bumper reinforcements as it can withstand impacts.
• Option B: It is used for many structural parts due to its high strength.
• Option C: Outer body panels are usually made of materials that are more formable and not necessarily ultra - high - strength steel (which is more for structural/load - bearing or impact - resistant parts).
• Option D: The strength of ultra - high - strength steel can be affected by heat (e.g., during welding or heat - treating processes gone wrong), so this statement is correct.

So the incorrect statement (the one that is not correct about ultra - high - strength steel) is option C.

Answer:

C) It is commonly used for outer body panels.
