← TechnologyWhich dimensional variance occurs when hot forging alloy steel components due to incomplete die closure?
A)Flash exceeding tolerance limits✓
B)Erosion of the die surfaces
C)Development of quench cracks
D)Grain boundary oxidation onset
💡 Explanation
Excessive flash leads to dimensional inaccuracies because incomplete die closure causes the forging to extrude material beyond specified boundaries via flash formation, therefore over-tolerance flash occurs, rather than die erosion, quench cracks, or oxidation influencing dimensional accuracy directly.
