SUS 312L

We could produce SUS 312L forging parts,SUS 312L forged rings, SUS 312L Rolled Rings,SUS 312L forging flanges, SUS 312L forging round bars, SUS 312L forged disks, SUS 312L forging bushings,SUS 312L forging discs,SUS 312L forged tubes, SUS 312L forging sleeves,SUS 312L forging tube sheets, SUS 312L forging shafts,SUS 312L forging pipes as per the requirement of the client
SUS 312L is an austenitic stainless steel with a high molybdenum content.
 We could delivery SUS 312L forging material as per the standard of EN 10088-2
We use EAF+VOD-ESR melting methods to melt the material of SUS 312L 
SUS 312L has excellent resistance to stress corrosion cracking allowing tube cold formingand may be used without the necessity to re-anneal at testing up to 120°C.
The Chemical Composition of SUS 312L  is as follows:

	C	Si	Mn	P	S	Ni	Cr	Mo	Cu	N
Min						17.50	19.00	6.00	0.50	0.16
Max	0.020	0.80	1.00	0.030	0.015	19.50	21.00	7.00	1.00	0.25

The mechanical property of SUS 312L is as follows:

0.2% proof stress (N/mm2)	Tensile strength (N/mm2)	Elongation (%)	Hardness
			(Hv)	(HB)
≥ 300	≥ 650	≥ 35	≤ 230	≤ 223

SUS 312L should be Quenching: 1150 to 1200°C ,Water, air cooling 
SUS 312L could be machined using techniques&equipment similar to 300 series stainless
Due to special mechanical properties of SUS 312L forging parts, there are many wide uses as followings:
