Nickel-base corrosion-resistant alloys have provided reliable service in aggressive industrial environments for many decades. However, with recent raw material cost increases, the cost of these alloys is prohibiting their use for some applications and designers are seeking more economical materials for construction. Conventional super-austenitic stainless steels have been successfully used but do not provide sufficient resistance for many applications. However, a 7% molybdenum advanced super-austenitic stainless steel designated UNS S31277 has been developed. This material offers resistance to corrosion equivalent to more highly alloyed nickel-base alloys in many applications. In addition the stainless steel product offers good fabricability and weldability. Thus, it is an economical alternative to these more costly alloys.

Key Words: Stainless Steel, Nickel Alloy, Super-Austenitic, Corrosion, Fabrication, Seawater, Marine, Chemical Processing, Welding, Molybdenum, Pitting, Crevice Corrosion

This work was undertaken to explore the possibility to extend the limits of 316L to higher temperatures.  The large scale test consists of a full ring pipe which is stressed externally and exposed internally to the test fluid.  The small scale tests are four-point-bend (4PB) tests in accordance with ISO15156-31 and EFC172.
