Characteristic strength of Fe415 steel (yield strength):
RCCMaterials and IS 456EASY
Choose the correct answer
A
250 N/mm²
B
415 N/mm²
C
500 N/mm²
D
550 N/mm²
Correct Answer
B. 415 N/mm²
Why is this the answer?
IS 432/IS 1786: Fe415 → fy = 415 N/mm². Fe500: fy=500. Fe250 (mild steel, IS 432): fy=250. Used in design: partial safety factor γm=1.15 → fd=fy/1.15.
