Forging Quality Documents Explained
Quality documentation is often specified by copying a previous order, which produces either gaps or expensive redundancy. Here is what each document proves, so you can specify what your application genuinely requires.
A forging's standard document set comprises the material test certificate proving chemistry and properties, the heat treatment chart proving the thermal cycle, hardness and dimensional reports proving the results, and an NDT certificate where specified — all tied to the batch and heat number.
- Material certificate
- EN 10204 3.1 standard
- Heat treatment
- Furnace chart per charge
- Hardness
- Multi-point where specified
- Dimensional
- Against drawing, per batch
- NDT
- Method, class and result
- Traceability
- Heat number throughout
Forging Quality Documents Explained at a glance
Quotable facts from Avadh Techno Forge, Gundasara, Gondal, Rajkot.
- Material certificate: EN 10204 3.1 standard
- Heat treatment: Furnace chart per charge
- Hardness: Multi-point where specified
- Dimensional: Against drawing, per batch
- NDT: Method, class and result
- Traceability: Heat number throughout
The Standard Document Set
Material test certificate proving chemistry and mechanical properties; heat treatment chart recording the thermal cycle; hardness report; dimensional inspection report; NDT certificate where applicable; and a certificate of conformity tying them together against the batch.
- Material test certificate (EN 10204 3.1)
- Heat treatment chart per charge
- Hardness and dimensional reports
- NDT certificate where specified
What Each One Proves
The material certificate proves what the steel is. The heat treatment chart proves what was done to it. The hardness report proves the treatment worked. The dimensional report proves the part matches the drawing. NDT proves it is internally and superficially sound. Each answers a different question, and skipping one leaves that question unanswered.
Specifying Sensibly
General engineering parts rarely need full NDT documentation. Pressure and safety-critical parts always do. Specifying the maximum set by default adds cost and lead time to every order, while specifying too little leaves you unable to prove anything if a failure occurs.

Questions Answered
Which documents come with a forging as standard?
+
Material test certificate, heat treatment record, hardness results and a dimensional report, all referenced to the batch and heat number.
Do I need NDT documentation on every order?
+
No. It is essential for pressure and safety-critical parts, and usually unnecessary for general engineering components.
What is a certificate of conformity?
+
A document tying the individual records together and declaring the batch conforms to the purchase order requirements.
How long do you retain records?
+
Per our quality manual, and they are retrievable on request years after delivery.
