2101 is a duplex (austenitic-ferritic) stainless steel with relatively low contents of alloying elements. It has high mechanical strength than austenitic stainless steels. Its good corrosion resistance is on par with that of most standard stainless steel grades. Combined these properties, 2101 can be utilized to optimize design with respect to strength, maintenance, durability and long-term cost efficiency.
Chemical Composition (wt. %)
- 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.
- Pulp & paper plant equipment.
- chemical process pressure vessels, piping, storage tanks and heat
- Waste water handle systems.
- Mixers and agitators.
Fabrication and Heat Treatment
2101 can be readily formed using various cold and hot working processes.

2101 generally have good weldability and can be welded using most of the welding methods used for austenitic stainless steel: SMAW, GTAW, GMAW, FCW, PAW, SAW, Laser welding, Resistance welding and High frequency welding.
