Product Description
34CrNiMo shaft for steam generator
1. Forgings Technical Specification
This type of steam generator shaft is Nangong's usual forging products. The shaft can be produced as per drawing or your specified requirements. Of course, more details can be well discussed after email or call us.
The manufacture process is as follows: smelting→Ingot →heating → forging → Heat treatment → Inspection → rough machining → UT → 2nd Heat treatment (Quenching and tempering or normalizing) →mechanical properties tests (our own laboratory)→ finishing machining → Inspection(DT, UT, MT or PT.) → Reports and qualified certificates, package and delivery.
Following eight items are Nangong's advantages and duty but not restricted to:
A. Chemical composition confirmation steps:
First, 100% mill certificate issued by the raw material supplier.
Second, re-inspect by our own laboratary using spectrograph.
B. Product engineering is verified and confirmed by two parties before production.
C. For mechanical properties, the relevant tracking photoes will be offered to customer if required.
D. Finish machining will be outsourcing to qualified and reliable nearby machining suppliers.
E. Ultrasonic test, magnetic particle test or liquid penetrant test can be done according to customer requirements or acceptance criteria.
F. Dimension test will be checked, recorded and issued reports 100% before shipment.
G. Package photos before shipment will be offered to customers.
H. Notice customer pay attention to the arrival date before goods arrive discharge port.
