Alloy 2205 Stainless Plate

duplex steel 2205

The yield energy is about twice that of austenitic stainless steels, thus permitting a designer to save weight and making the alloy more cost competitive when compared to 316L or 317L. The chromium, molybdenum, and nitrogen in 2205 duplex stainless steel plate additionally provide excellent resistance to pitting and crevice corrosion even in very oxidizing and acidic options. This leads to a microstructure that provides corrosion properties and toughness roughly equal to that of the mother or father metallic. Testing according to ASTM A262 PRE (Strauss´ take a look at) presents no issues for welded joints in Sandvik SAF 2205™, which move with out reservations.

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.

Characteristics of Stainless Steel Sheet and Plate:
High corrosion resistance
High strength
High toughness and impact resistance
Temperature resistance
High workability, including machining, stamping, fabricating and welding
Smooth surface finish that can be easily clean


This combination permits the alloy to be stronger and tougher than commonplace austenitic steels. Duplex stainless steels like 2205 additionally maintain good weldability of their thickest sections, and they are much extra immune to stress corrosion cracking than normal austenitic steels. Sandvik SAF 2205™ possesses higher strength and better corrosion resistance than odd austenitic stainless steels. Consequently, Sandvik SAF 2205, has considerably better fatigue strength under corrosive situations than such steels.

Stress relieving isn’t required or really helpful; nevertheless, if it have to be performed, the fabric should receive a full resolution anneal at 1900°F minimal, adopted by speedy cooling or water quenching. Grade 2205 stainless-steel reveals wonderful corrosion resistance, much larger than that of grade 316.

  • Duplex 2205 Plates Duplex 2205 Stainless Steel Plates is used extensively in functions that require good corrosion resistance and energy.
  • It has high mechanical strength and high resistance to emphasize corrosion cracking and corrosion fatigue.
  • Marc Steel is a known dealer of Duplex Steel 2205 Plates, which has Good to excellent resistance to pitting and crevice corrosion.
  • Duplex Stainless Steel UNS S32205 Plates is nitrogen enhanced duplex stainless-steel that was developed to combat frequent corrosion problems encountered with the 300 series stainless steels.
  • Combining many of the helpful properties of both ferritic and austenitic steels, 2205 Duplex Stainless Steel is the most extensively used duplex stainless-steel grade.

We produce ASTM/ASME Grade 304, Grade 304L,304h, 316, 316L, 316H, 316TI, 321, 321H, 309S, 309H, 310S, 310H, 410S, 2205, 904L, 2507, 254, gh3030, 625, 253MA, S30815, 317L, Type 317, 316lN, 8020, 800, 800H, C276, S32304 and others special requirement stainless steel grade.

It is designed to mix improved resistance to emphasize corrosion cracking, pitting and crevice corrosion. Duplex 2205 provides nearly double the corrosion resistance typical in other austenitic stainless steels. Whilst duplex stainless steels are thought-about proof against stress corrosion cracking, they don’t seem to be as proof against this type of attack as ferritic stainless steels.

It is essentially the most widely used duplex stainless-steel grade and is characterized by high yield power, double that of the usual austenitic chrome steel grades. It additionally demonstrates good fatigue energy, as well as outstanding resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion in extreme environments. In other words, duplex alloys have the energy of ferritic while retaining the corrosion resistance of the austenitic . 2205 Steel Plates is a duplex alloy with a microstructure, when warmth handled correctly, of nearly equal proportions of austenite and ferrite. Meanwhile, S32205 provides higher guaranteed corrosion resistance, but much of the S31803 presently produced also complies with S32205.

As a result, duplex stainless steels show properties characteristic of both austenitic and ferritic stainless steels. This mixture of properties can imply some compromise compared with pure austenitic and pure ferritic grades. Alloy 2205 duplex chrome steel plate possesses good weldability. The goal of welding 2205 is that the weld metal and heat-affected zone retain the corrosion resistance, strength, and toughness of the base metal.

Is 2205 duplex stainless steel magnetic?

The best known duplex grade, 2205, resists corrosion even better than 316 because it contains 22% of chromium and 3% of molybdenum. Austral Wright Metals stock two New Generation ferritic stainless steel grades, AWM 404GP® and 445M2. Both are magnetic, because both are ferritic.

The welding of 2205 isn’t difficult, however it’s essential to design welding procedures that result in a good section balance after welding and will keep away from precipitation of detrimental intermetallic or nonmetallic phases. Alloy 2205 duplex stainless steel plate combines excessive energy and high corrosion resistance to produce excessive corrosion fatigue power. Applications during which processing equipment is subject to each an aggresively corrosive enviroment and to cycle loading can profit from the properties of 2205 duplex chrome steel plate. Because of its high chromium (22%), molybdenum (3%), and nitrogen (0.18%) contents, the corrosion resistance properties of 2205 duplex chrome steel plate are superior to that of 316L or 317L in most environments. Sandmeyer Steel Company has an extensive inventory of 2205 duplex chrome steel plate in thicknesses from 3/sixteen” (4.8mm) through 6″ (152.4mm).
