Heat Code Traceability (HCT) Appendix 1
HCT refers to the fact that a specific part can be traced back
to the original mill heat of metal from which it was made.
Beginning with the original melt, a package of documents
is created which completely describes the metal in physical
and chemical terms. The end result is that a number, which
is permanently stamped to the part, refers back to the
document package. HCT offers these advantages:
•
Raw materials for manufacture must meet code
requirements. This can be verified through documentation
so that the customer is certain that what is ordered is
received.
•
HCT provides a record of chemical analysis with the raw
material.
•
HCT relieves the user of Parker instrumentation fittings
of any doubts. It acts as an assurance for today and for
tomorrow.
In addition to the documentation of chemical and physical
properties, great care is taken throughout the manufacture
of Parker’s connectors to ensure that potential stress
corrosion will not be a problem in normal usage of the
parts. Manufacturing processes avoid exposure of the parts
to mercury or halogens, and control of thermal treatment
avoids the condition known as continuous grain boundary
carbide precipitation.
