B) The minimum stress that a material can withstand before it breaks.
C) The maximum stress that a material can withstand before it deforms to plastic
D) The UTS minus the yield point.
A) The maximum stress that a material can withstand before it breaks.
In order to obtain specific steel properties, special processes can be used such as
vacuum degassing. What does vacuum degassing do?
A) It increases the gas content (hydrogen and oxygen).
B) It reduces the gas content (hydrogen and oxygen).
C) It removes the surface area of the melt by suction.
D) It uses suction to stir the melt.
B) It reduces the gas content (hydrogen and oxygen).
During the rolling of a steel plate, non-metallic inclusions in the steel plate may
produce:
A) regions where inclusions accumulate.
B) regions free of inclusions.
C) elongated inclusions.
D) spherical inclusions.

,not A
C) elongated inclusions.
Why are silicon and/or aluminum added to steel?
A) To increase carbon content.
B) To increase the grain size of the steel.
C) To remove dissolved oxygen.
D) To reduce the toughness of steel.
C) To remove dissolved oxygen.
Groove welds can experience problems due to segregation in rimmed steel.
(True/False)
True.
Groove welds can experience problems due to segregation in rimmed steel. In
rimmed steel, there is a concentration of impurities and non-metallic inclusions
near the center of the ingot, which can lead to segregation issues during welding.
This can result in weld defects and reduced weld quality.
Lamellar tearing in a welded connection can be mitigated by:
A) reducing the temperatures used in welding.
B) reducing the volume of weld metal from complete to partial penetration.
C) changing the weld process used.
D) changing the base materials used.
B) reducing the volume of weld metal from complete to partial penetration.
There are many organizations issuing steel specifications. These include
A) CSA, CWB, TSSA, ABSA, and ASTM.
B) CSA, SMAW, AISI, ASME, and ASTM.
C) CSA, SAE, ASI, ASME, and ASTM.
D) CSA, SAE, AISI, ASME, and ASTM.
D) CSA, SAE, AISI, ASME, and ASTM.

The ASTM designation system for metals consists of a letter. What does A
represent?
A) Ferrous materials.
B) Non-ferrous materials.
C) Aluminum.
D) Atomic grade materials.
A) Ferrous materials.
What designates that AISI 4340 refers to nickel-chromium-molybdenum steel?
A) The first digit
B) The first two digits
C) The first three digits
D) The last digit
