DI Hardenability Calculator App

The method of Jominy hardenability calculation from the chemical Ideal

Diameter* (DI) of a steel. DI Calculator includes carbon multiplying factors and

improved the correlation of the boron factor with both carbon and alloy content

to provide increased accuracy of both the calculated DI and Jominy hardenability

curves. Composition ranges shown below:

ELEMENT

RANGE (wt. %)

-------

-------------

CARBON

0.10 - 0.70

MANGANESE

0.50 - 1.65

SILICON

0.15 - 0.60

CHROMIUM

1.35 MAX

NICKEL

1.50 MAX

MOLYBDENUM

0.55 MAX

COPPER 0.35 MAX

VANADIUM

0.2 MAX

ZIRCONIUM

0.0

*DI represents the diameter of a round steel bar that will harden at the center

to 50% martensite when subjected to an ideal quench.

Multiplying factors are based on an average grain size of 7.

For design purposes, the calculated DI and Jominy hardenability curves are valid

only within the DI, alloy factor, and and chemical composition ranges stated

above.

However, to facilitate melting process, control for higher alloy steels,

Hardenability Multiplying Factors have been included for calculating the DI

within the following chemical composition ranges:

ELEMENT

RANGE (wt. %)

-------

-------------

CARBON

0.00 - 0.90

MANGANESE

0.00 - 1.95

SILICON

0.00 - 2.00

CHROMIUM

0.00 - 2.5

NICKEL

0.00 - 3.50

MOLYBDENUM

0.00 - 0.55

Copper

0.00 - 0.55

COMPOSITION INPUT

1. Touch on each compositions text box and enter percents.

2. Touch Yes or No for boron to calculate a boron steel or non-boron steel.

3. Touching the Calculate button calculates the multiplying factors,

the DI, the alloy factor, the boron factor, the carbon equivalent,

and the Jominy Hardenability curve.

4. The graph button displays the graph of the hardenability curve.

5. The print button prints the calculated values.

6. The email button will email the calculated values.

---------------------------------------------------------------

DATA DISPLAY

The data display screen contains the following information:

Alloy % entered

Multiplying factors used to generate DI and alloy Factor

Calculated DI

Alloy Factor

Boron Factor - for boron steels only

Carbon equivalent of the composition using:

%Mn (%Cr + %Mo + %Va) (%Ni + %Cu)

CE = %C + --- + ----------------- + -----------

6 5 15

Calculated hardness for each J-position listed at the bottom of the screen.

All results are rounded to 2 decimal places (3rd decimal => 5 rounds up)
