Alloy 28

We could produce Alloy 28 forging parts,Alloy 28 forged rings, Alloy 28 Rolled Rings,Alloy 28 forging flanges, Alloy 28 forging round bars, Alloy 28 forged disks, Alloy 28 forging bushings,Alloy 28 forging discs,Alloy 28 forged tubes, Alloy 28 forging sleeves,Alloy 28 forging tube sheets, Alloy 28 forging shafts,Alloy 28 forging pipes as per the requirement of the client
Alloy 28 is a a nickel-iron-chromium alloy with additions of molybdenum and copper.
We could delivery Alloy 28 forging material as per the standard of ASTM
We use EAF+VOD-ESR melting methods to melt the material of Alloy 28 
As per heat treatment of Alloy 28 forged parts, it should be Solution annealing 1100-1160°C (2010-2120°F), 10-30 minutes, quenching in water. 
The Chemical Composition of Alloy 28  is as follows:

Element	Content (%)
Iron, Fe	29-40.4
Nickel, Ni	30-34
Chromium, Cr	26-28
Molybdenum, Mo	3-4
Manganese, Mn	≤2.5
Others	Remainder

The mechanical property of Alloy 28 is as follows:

Properties	Metric
Tensile strength(annealed)	500 MPa
Yield strength(annealed)	214 MPa
Elongation at Break(Cold worked)	15%
Hardness, Rockwell B	80-90
Hardness, Rockwell C	33

Alloy 28 is requires an adjustment of tooling data and machining method, in order to achieve satisfactory results. Compared to Sanmac 316/316L, the cutting speed must be reduced by approximately 50-55% when turning Alloy 28 with coated, cemented carbide tools. Much the same applies to other operations. Feeds should only be reduced slightly and with care
