Q1: Brass parts with high residual tensile stress at the surface are susceptible to season cracking (i.e. spontaneous cracking occuring on exposure to atmospheric corrosion), if its zinc percentage is more thanA 5
B 10
C 20
D 35
ANS:C - 20 zinc percentage exceeding 35% are more prone to season cracking, especially if they also have high residual tensile stress at the surface. A zinc percentage of 20% is less likely to cause season cracking compared to compositions with higher zinc content, such as those exceeding 35%. Here's an explanation:
