TOP-HTTRM: Heat Treater Test Result Monitoring 

Rev: 12/06/2017

Scope: This procedure describes the methods to be used to frequently monitor the reliability of hardness and tensile testing results being provided by authorized heat treat suppliers. "Frequently monitor" means that we double-check the hardness results of such suppliers as often as the Post Forge Supervisor sees fit, as long as each supplier is double-checked at least once each month in which they supply to us.

Procedure:

STEP	WHO	WHEN	INFO TO USE	WHAT TO DO
HEAT TREATER HARDNESS MONITORING
a1	Post Forge Lead Man	As required by Traveler or at Post Forge Lead Man discretion	Traveler	Double-check authorized heat treater's hardness per TOP-HARDT.
a2	Post Forge Supervisor	Completion of TOP-HARDT	Heat treater's certs; Trinity Hardness Inspection Sheet, Traveler	Compare heat treater's hardness results to in-house results.
a3	Post Forge Supervisor	If in-house results do not agree with heat treater's	Determination from previous step	Notify QA Manager of results via Hardness Inspection Sheet if they fail.
a4	QA Manager	Upon being informed that in-house results differ from heat treater's	Heat treater's certs; Trinity Hardness Inspection Sheet; sample forgings	Review results; have heat treater check a sample of the forgings that Trinity checked; issue CAR per TOP-CARRR if heat treater's results are in error (use outside arbiter if necessary); notify Post Forge Supervisor of determination.
a5	Post Forge Supervisor	Upon notification from QA Manager from previous step	QA Manager's notification	Record determination and ensure parts are to specification.
a6	Post Forge Supervisor	After monitoring complete	Trinity Hardness Inspection Sheet	Forward Trinity Hardness Inspection Sheet results to QA Assistant.
a7	QA Assistant	Receives results	Trinity Hardness Inspection Sheet	Scan into M2M Certs for later analysis of authorized heat treat supplier.
