ASTM A789 S32205 (UNS S32205) duplex stainless steel tube

1. Brief introduction

ASTM A789 S32205 (UNS S32205) duplex steel tubes are high-performance tubular products designed for extreme environments requiring exceptional strength and corrosion resistance. With a balanced microstructure of 50% austenite and 50% ferrite, these pipes deliver yield strength up to 450 MPa – twice that of standard 316L stainless steel – while maintaining excellent toughness across temperatures ranging from -50°C to 300°C.

2. Chemical composition (ASTM A789 standard)

element	Content (wt.%)
Cr	22.0 - 23.0
Ni	4.5 - 6.5
Mo	3.0 - 3.5
N	0.14 - 0.20
Mn	≤2.00
Si	≤1.00
C	≤0.030
P	≤0.030
S	≤0.020
