VANFORGE supply hot-worked alloy, carbon and carbon-boron steels in a variety of compositions and sizes.

Hardenability

The relative ability of a steel to harden under heat treatment becomes apparent in the degree to which the material hardens when quenched at different cooling rates. It is measured quantitatively, usually by noting the extent or depth of hardening of a standard size and shape test specimen in a standardized quench. In the “end-quench” test the “depth of hardening” is the distance along the specimen from the quenched end to a given hardness.

Ordering Information

Orders for material under this specification should include the following information, in proper sequence:

1 Quantity (weight),

2 Name of material (alloy, carbon, or carbon-boron steel),

3 Cross-sectional shape,

4 Size,

5 Length,

6 Grade,

7 End-quenched hardenability (see Section 9),

8 Report of heat analysis, if desired (see Section 7),

9 Special straightness, if required,

10 ASTM designation and date of issue,

11 End use or special requirements, and

12 Leaded steel, when required.
