LDX 2101* is a duplex (austenitic ferritic) stainless steel with relatively low contents of alloying elements. The grade has high mechanical strength, similar to that of other duplex grades. Its good corrosion resistance is on par with that of most standard stainless steel grades. Combined, these properties can be utilized to optimize design with respect to strength, maintenance, durability and long term cost efficiency. LDX 2101 main characteristics:- High strength - approximately twice as high proof strength as austenitic stainless steels ASTM 304 and 316
- Very good resistance to stress corrosion cracking
- Good resistance to general corrosion and pitting
- High energy absorption
- Physical properties that offer design advantages
- Ease of fabrication and good toughness
- Very good weldability
Applications: General purpose applications and environments:- Building and construction
- Storage tanks
- Reinforcement bars
- Water piping
Microstructure: The balanced chemical composition of LDX 2101 results in a microstructure containing approximately equal amounts of ferrite and austenite after annealing at a temperature of 1050°C (1920 F). Due to its relatively low alloying content, LDX 2101 is less prone to precipitaition of intermetallic phases than other duplex steels. The high nitrogen content results in rapid reformation of austenite in weld thermal cycles.Information provided by Sandvik |
