Chloride stress corrosion cracking of stainless steels can happen when the required circumstances of temperature, tensile stress, oxygen, and chlorides are present. Since these conditions are not easily controlled, stress corrosion cracking has often been a barrier to utilizing 304L, 316L, or 317L. The duplex microstructure is understood to improve the stress corrosion cracking resistance of stainless steels.

The Helix in Marina Bay, Singapore and the Harbor Drive Pedestrian Bridge in San Diego, CA both use 2205 as a primary structural providing excessive power, sustainable structures with cutting-edge design. The pitting resistance of an austenitic chrome steel may be related on to alloy composition, where chromium, molybdenum and nitrogen are a weight %.

Stainless Steel Duplex 2205 is the most widely used duplex (ferritic/austenitic) stainless steel grade. It finds purposes as a result of each wonderful corrosion resistance and high strength.


  • Duplex 2205 supplies practically double the corrosion resistance typical in different austenitic stainless steels.
  • Our Duplex 2205 Stainless Steelis a nitrogen-enhanced duplex used in functions requiring high strength and excellent corrosion resistance.
  • It is designed to combine improved resistance to stress corrosion cracking, pitting and crevice corrosion.

Alloy 2205 duplex stainless-steel plate combines high energy and excessive corrosion resistance to provide excessive corrosion fatigue strength. Applications in which processing tools is subject to each an aggresively corrosive enviroment and to cycle loading can profit from the properties of 2205 duplex stainless steel plate. Because of its high chromium (22%), molybdenum (3%), and nitrogen (zero.18%) contents, the corrosion resistance properties of 2205 duplex chrome steel plate are superior to that of 316L or 317L in most environments.

Alloy 2205 duplex chrome steel plate possesses good weldability. The objective of welding 2205 is that the weld steel and heat-affected zone (HAZ) retain the corrosion resistance, power, and toughness of the base steel. The welding of 2205 is not difficult, but it is necessary to design welding procedures that result in a favorable section balance after welding and can keep away from precipitation of detrimental intermetallic or nonmetallic phases. The chromium, molybdenum, and nitrogen in 2205 duplex stainless-steel plate additionally provide glorious resistance to pitting and crevice corrosion even in very oxidizing and acidic options. Sandmeyer Steel Company has an in depth stock of 2205 duplex chrome steel plate in thicknesses from 3/sixteen” (four.8mm) via 6″ (152.4mm).

Grade 2205 chrome steel displays excellent corrosion resistance, a lot greater than that of grade 316. It resists localized corrosion types like intergranular, crevice and pitting.

2205 is a duplex stainless steel, with a chemical composition of nearly equal proportions of austenite and ferrite. This mixture allows the alloy to be stronger and tougher than normal austenitic steels. Duplex stainless steels like 2205 also maintain good weldability of their thickest sections, and they’re much more resistant to stress corrosion cracking than standard austenitic steels.

We have thousands tons stock of stainless steel sheet and coil with various size and grade,mainly include austenitic stainless steel, martens stainless steel (including precipitation hardened stainless steel sheet & coil), ferritic stainless steel, and duplex stainless steel.
