We could produce Alloy 20 forging parts,Alloy 20 forged rings, Alloy 20 Rolled Rings,Alloy 20 forging flanges, Alloy 20 forging round bars, Alloy 20 forged disks, Alloy 20 forging bushings,Alloy 20 forging discs,Alloy 20 forged tubes, Alloy 20 forging sleeves,Alloy 20 forging tube sheets, Alloy 20 forging shafts,Alloy 20 forging pipes as per the requirement of the client
Alloy 20 is a nickel–chromium–molybdenum stainless steel alloy developed for applications involving sulfuric acid.

We could delivery Alloy 20 forging material as per the standard of ASTM B462

Alloy 20 will be melted by AOD refining or vacuum induction melting. Vacuum arc or electroslag remelting procedure

Alloy 20 should be heated between 2100°F and 2250°F with careful temperature control insuring that 

the material not fall below 1800°F prior to forging. After hot working, anneal the material by heating to 

1725°F and 1850°F for a minimum of 30 minutes per inch of thickness followed by water quench.

The Chemical Composition of Alloy 20 is as follows:

Fe...........................................................Balance
Ni..............................................32.00% to 38.00%
Cr.............................................19.00% to 21.00%
Mo...............................................2.00% to 3.00%
Cu................................................3.00% to 4.00%
Cb + Ta..................................(8 x C%) to 1.00%
Mn.............................................2.00% Maximum
Si................................................1.00% Maximum
P..............................................0.045% Maximum
S ..............................................0.035% Maximum
C...............................................0.07% Maximum
The mechanical property of Alloy 20 is as follows:

Tensile Strength	Min 80KSI	Min 552MPA
Yield Strength	Min 35KSI	MIN 242MPA
Elongation	Min 30%

 

Alloy 20  resists pitting and chloride ion corrosion and its copper content protects it from sulfuric acid.

Due to special mechanical properties of Alloy 20 forging parts, there are many wide uses as followings:

Alloy 20 seamless rolled rings and  Alloy 20 forging shafts that is used in Sulfuric acid pickling tanks, racks and heating coils,Phosphate coating drums and racks
