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.

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.
Duplex 2205 is a two-phase, ferritic, austenitic chromium–molybdenum–nickel alloyed stainless steel. It is the most widely used duplex stainless steel grade and is characterized by high yield strength, double that of the standard austenitic stainless steel grades. It also demonstrates good fatigue strength, as well as outstanding resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion in severe environments.

2507 is a super duplex stainless steel with designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment. The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion. The high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion.
