Shock Resistant Steel

Question 1

Characteristics of shock resistant steel?

Answer 1

-High impact resistance
-High Strength
-High toughness
-Wear resistance
-high harden-ability and softening resistance

Question 2

Most important characteristic ?

Answer 2

Toughness

Question 3

What is toughness defined as again?

Answer 3

The amount of energy a material can absorb before failure

Question 4

What does tempering actually do?

Answer 4

-ductility increases
-strength decreases

Question 5

What is the difference between S7 and S5 steel?

(Use reference sheet)

Answer 5

-S7 has added Mo and Cr as well as being oil quenched

-S5 unless a complex geometry is needed is water quenched
-S5 classed as general purpose medium hardening-ability
