NAS 75N

We could produce NAS 75N forging parts,NAS 75N forged rings, NAS 75N Rolled Rings,NAS 75N forging flanges, NAS 75N forging round bars, NAS 75N forged disks, NAS 75N forging bushings,NAS 75N forging discs,NAS 75N forged tubes, NAS 75N forging sleeves,NAS 75N forging tube sheets, NAS 75N forging shafts,NAS 75N forging pipes as per the requirement of the client
NAS 75N is a super duplex stainless steel
We could delivery NAS 75N forging material as per the standard of JIS
We use EAF+VOD-ESR melting methods to melt the material of NAS 75N 
NAS 75N is superior to the more expensive grades such as alloy 20 or alloy 825 and is superior to duplex 2205 and 2507 super duplex at most concentrationsn
The Chemical Composition of NAS 75N  is as follows:

	C	Si	Mn	P	S	Cr	Ni	Mo	Cu	N	W	PREN	Fe
Min	•	•	•	•	•	24.00	6.00	3.00	0.50	0.20	0.50	40.00	0.00
Max	0.03	1.00	1.00	0.030	0.010	26.00	8.00	4.00	1.00	0.30	1.00	•	0.00

The mechanical property of NAS 75N is as follows:

U.T.S	109 KSI Min	(750 N/mm2)
0.2% Proof Stress	80 KSI Min	(550 N/mm2)
Elongation	25 %
Red of Area	45 %
CVN Impacts @ -46°C (-50°F)	45 Joules	(33 ft-lbf)

NAS 75N should be Solution annealing 1130 o C + water quench.
NAS 75N 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 NAS 75N with coated, cemented carbide tools. Much the same applies to other operations. Feeds should only be reduced slightly and with care
Due to special mechanical properties of NAS 75N forging parts, there are many wide uses as followings:
