FOllowing is melting methods of Forging steel valve balls
1 EAF: Electric Arc Furnace
2 EAF+LF+VD: Refined-smelting and vacuum degassing
3 EAF+ESR: Electro Slag Remelting
4 EAF+PESR: protective atmosphere Electro Slag Remelting
5 VIM+PESR: Vacuum induction melting
We could forged, heat treatment and final machined valve balls as per clients drawing
We could do following surface finish of forged valve balls
Surface Hardening Materials Tungsten Carbide TCC, Chromium Carbide CCC, Stellite STL,
Nickel Bace Alloy Ni60 / Ni55, Plasma Nitriding, Hard Chromium HCR,
Nickel Phosphorus ENP
We are able to provide any kind of NDE ( Non-Destructive Examination) tests for our all finished forged steel valve balls.
PT (Penetrant test)
UT (Ultrasonic test)
PMI (Positive material Identification)
MT (Magnetic test)
Thickness test (for cladding, plating or coating)
Alcohol Test (for MTM kits)
Corrosion Test
ALl our finished forged valve balls will have Inspection certificate 3.1 acc.EN 10204
The inspection Certificate shall include:
1. Chemical Composition.
2.Melting method
3. Tensile testing acc.DIN EN 10002-1 (Tensile strength Technical elastic limit =0,2%,Elongation,Throat
4. Beam Impact Test (average out.of 3 testings) acc.DIN EN 10045-1 by using ISO-V notch specimen
5. Hardness test according DIN EN 10003-1 (Brinell)o DIN EN 10109-1(Rockwell C)at three spots across the total length
6.Proof of the inner consistency (UItrasonic testing acc.EN10228-3 Class 3 C)
7. Information on heat treatments (tempering,stress relief annealing,normalizing)
8. Dimension inspection (Dimension record)
9.Proof of surface roughness Rz in the bearing zones
10.Proof that the entire finished product is free from cracks (Magnetic particle test acc.EN10228-1 class 4)
