We could produce Z20CDNbV11,Z 20 CDNbV 11 forged material  with diameters ranging from 100MM to 6000MM and with weights from 10KGS to 15000KGS

We could supply Z20CDNbV11 forging turbine material as per the standard of EN10204-3.1 or EN10204-3.2 of third party such TUV, DNV,BV,SGS and so on

Z20CDNbV11 forged steel raw material is normal melting by Basic Electric Furnace (EAF, AOD, VOD) or VIM + Electroslag remelting. (ESR)

Following is production process for Z20CDNbV11 forged Turbine Blades steel Flat  Bars

Forging process flow quality control: Raw material steel ingot into warehouse(test the chemical content) → Cutting→ Heating(Furnace temperture test) → Heat treatment after forging(Furnace temperture test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal diamention, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment

We produce Z20CDNbV11 forged steel turbine blade material as per standard of NF A 35-558-1983
