SUS 317 is higher chromium, nickel and molybdenum version of 316 stainless designed principally for increased strength and corrosion resistance.
 We use EAF+VOD-ESR melting methods to melt the material of SUS 317 
As per heat treatment of SUS 317 forged parts, it is annealed at 1010-1121°C (1850-2050°F) followed by cooling.
The chemical composition of SUS 317 is as follows:

C		0.08 max
Cr		18 - 20
Fe		Balance
Mn		2 max
Mo		3 - 4
Ni		11 - 15
P		0.045 max
Si		1 max
S		0.03 max

The mechanical property of SUS 317 is as follows:

Tensile strength	620 MPa
Yield strength	275 MPa
Elastic modulus	193 GPa
Poisson's ratio	0.27-0.30
Elongation at break (in 50 mm)	45%
Hardness, Rockwell B	85

 SUS 317 resists atmospheric corrosion, as well as, moderately oxidizing and reducing environments
