Flow Corrosion Behavior of Austenitic Stainless Steels

The corrosion behavior of the two austenitic stainless steels has been compared with a superduplex stainless steel, UNS S32760, exposed to the same hydrodynamic conditions. INTRODUCTION The influence of fluid velocity on metastable and stable pit propagation of austenitic stainless steels, Type 304L (UNS S30403)(1) and Type 316L (UNS S31603), is examined.

Austenitic stainless steel

Austenitic stainless steel is one of the five classes of stainless steel by crystalline structure (along with ferritic, martensitic, duplex and precipitation hardened).Its primary crystalline structure is austenite (face-centered cubic) and it prevents steels from being hardenable by heat treatment and makes them essentially non-magnetic.

Improving the corrosion wear resistance of AISI 316L

2008/12/10In order to overcome the problem of corrosion wear of AISI 316L stainless steel (SS), two kinds of composite alloying layers were prepared by a duplex treatment, consisting of Ni/nano-SiC and Ni/nano-SiO 2 predeposited by brush plating, respectively, and subsequent surface alloying with Ni–Cr–Mo–Cu by a double glow process.

Influence of austenite stability on predicted cyclic stress

For the other two metastable austenitic stainless steels considered in the study (AISI 321 and AISI 348), an nc value of 2.2 is also reasonable [6]. Thus, nc is less than nm as expected, but nc does not increase with increases in plastic strain amplitude.
