Grade 926 Super Austenitic Stainless Steel Strip UNS N08926 for Marine Applications

1. Introduction to Alloy 926

Alloy 926 is a super-austenitic stainless steel enhanced with high molybdenum (6.0–7.0%), nitrogen (0.15–0.25%), and nickel (24–26%). Designed for extreme corrosive environments, it bridges the gap between standard austenitic steels (e.g., 316L) and high-cost nickel alloys. Its key features include:

• Exceptional corrosion resistance in chloride-rich media (e.g., seawater, acids)246.

• High strength and ductility due to nitrogen strengthening18.

• Applications span marine engineering, chemical processing, and pollution control systems510.
