Rockwell B: ~107 (major load 100)
Rockwell C: hardness 25; tensile 120 psi (major load 150)

Vicker Test:
Average length = 115, Hardness 207 (load of 200)

Rockwell C: 14 - no listed tensile strenght value.

Rockwell B: 94 = 98 kips of tensile strength (trial 1) and 91 = 91 kips of tensile strength (trail 2)

*Rockwell C test used a major load of 150.

*Rockwell B test used a major load of 100.

Vicker: Average length was 113 - Hardness of 215

*Vicker tests performed with a load of 200.

Rockwell B: 23 - no listed data

Rockwell C: 63 (trial 1) and 64 (trial 2) - no listed tnesile strength

Vicker: Average length of 58 yielded a hardness of 802

*same loads applied as before the heating and quenching

Rockwell C: No Value on Table

Rockwell B: 95= 101 kips of tensile strength

Vicker: average length: 104.5 hardness: 252

Rockwell B: score: 76 Tensile Strength: N/A

Rockwell C:

Trial 1: score: 38 Tensile Strength: 171 kips

Trial 2: score: 41 Tensile Strength: 188 kips

Vickers:

Trial 1: Average Length: 94.5 Score: 308

Before

Rockwell C: 106 - no listed tensile strength value.
Rockwell B: hardness 96 = 103 kips of tensile strength (load:100)

Vicker test:
Average length(trial 1) = 109.5, Hardness 228(load of 200)
Average length(trial 2) = 109, Hardness 231(load of 200)

After

Rockwell C: 67.5 - no listed tensile strength value.
Rockwell B: hardness 113.5 - too high for chart (tensile strength > 116) (load:100)

Vicker test:
Average length(trial 1) = 89.5, Hardness 342(load of 200)
