The steel S.A.E 1025 has an ultimate tensile strength of __________(a)

1.	The steel S.A.E 1025 has an ultimate tensile strength of __________(a) 12,000 p.s.i(b) 6,000 p.s.i(c) 55,000 p.s.i(d) 22,000 p.s.iThis question was addressed to me in an online quiz.My question is from Properties of Steel and its Alloys in portion Steel and its Alloys of Aerospace Materials & Processes
Answer» Correct option is (c) 55,000 p.s.i For explanation I would say: The STEEL S.A.E 1025 is also called mild carbon steel and cold-rolled stock. It has an ULTIMATE tensile strength of 55,000 p.s.i. It is bought cold-rolled for aircraft manufacturing purposes. It DEVELOPS a higher strength when HEAT treated.
