QUESTION 3

RsQ_002Hot work steels combine ___________ with good wear resistance and shock resistance.

compressive stress

tensile stress

hot strength

a.

Shear on the die

b.

Angular clearance in the die

c.

Shear on the punch

Explanation / Answer

(1)- During the design of welding fixture, minimum heat loss from the weld area is required to avoids cracks. To reduce such heat loss, large fixture masses should not be placed close to the weld line.

Thus the statement is true.

(2)- in a blanking die, to reduce the possibility of slug clinging to the die, shear is provided to the die.

(3)- hot work steels combine compressive stress with good wear resistance and shock resistance.
