FOllowing is melting methods of forged steel Gate Valve Wedge Disc
1. Step 1- Basic EF
Step 2- Either Argon Oxygen Decarburization (AOD) or Vacuum Oxygen Decarburization (VOD) or Vacuum Degrassing.
Step 3- Either Electroslag Remelting (ESR) or Electroflux Remelting (EFR) or Vacuum Arc Remelting (VAR).
Optional Step 4- Vacuum Arc Remelting (VAR)
OR
2. Step 1- Vacuum Induction Melting (VIM)
Step 2- Either Electroslag Remelting (ESR) or Electroflux Remelting (EFR) or Vacuum Arc Remelting (VAR).

Following is surface treatment that we could do for forged steel Gate Valve Wedge Disc
Coating:Nitridation, ENP, Chrome Plating, Tungsten Carbide, Chrome Carbide, Stellitee, Inconel, etc
Coating
Thermal Spray and Cold Spray:
Nitridation, ENP, Chrome Plating,
HVOF Tungsten Carbide, HVOF Chrome Carbide,
Stellite 6# 12# 20#, Inconel, etc
Our our finished forging steel Gate Valve Wedge Disc will have following non-destructive testing (NDT) methods such as ultrasonic testing, magnetic particle inspection, and X-ray testing, as well as mechanical testing for tensile strength, hardness, and impact resistance.
ALl our finished forging steel Gate Valve Wedge Disc 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)
