2304 Duplex Stainless Steel PlateDuplex 2304 is a 23% chromium, 4% nickel, molybdenum-free duplex stainless metal whose shape is a stability of ferritic and austenitic. It has common corrosion resistance comparable or higher than Alloys 304L and 316L however with yield energy almost double that of austenitic stainless steels.

AISI 329 Duplex Stainless Steel Plate belongs to a specification of duplex steel grades.

2304 duplex stainless steel bar:Stainless steel is a production which not easy rust, acid resistance and corrosion resistance, so it is widely used in light industry, heavy industry, daily necessities and the decoration industry.

2507 (UNS S32750) duplex stainless steel has strong strength and corrosion resistance, which is mainly used in chemical processing, petrochemical industry and subsea equipment. It has strong chloride corrosion resistance, high thermal conductivity and low coefficient of thermal expansion. The high content of chromium, molybdenum and nitrogen makes it highly resistant to patchy, crevice and general corrosion.

2205 Duplex Stainless Steel PlateDuplex 2205 is a two-phase, ferritic, austenitic 22% chromium, 3% molybdenum, 5 to 6% 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.

329 is a duplex stainless steel with optimized S and Mo to improve mechanical properties.

Duplex 2507 Stainless Steel PlateAlloy 2507 is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel 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.

Duplex 2304 is a 23% chromium, 4% nickel, molybdenum-free duplex stainless steel whose structure is a balance of ferritic and austenitic.

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.

s31803 Duplex stainless steel is a kind of  Medium alloy stainless steel,it's PREN value is 32-33, and its corrosion resistance is between AISI 316L and 6%Mo+N austenitic stainless steel.Duplex stainless steel has the characteristics of both austenitic stainless steel and ferritic stainless steel because it has austenite + ferrite dual-phase structure, and the content of the two phase structures is basically the same. The yield strength can reach 400Mpa ~ 550MPa, which is twice that of ordinary austenitic stainless steel.

Duplex 2304 is two-phase, ferritic, austenitic which contain chromium 23%,nickel 4%, molybdenum-free duplex stainless steel. Itscorrosion resistance properties are similar to 316L stainless steel. Furthemore it has mechanical properties twice to 304L stainless steel/316Lstainless steel grades. And this becomes helpful for the manufacturers to save weight especially for properly designed pressure vessel applications.

1. Compared with 316L and 317L austenitic stainless steel,2205 alloy has better performance in corrosion resistance and crack corrosion, it has high corrosion resistance, compared with austenite, its thermal expansion coefficient is lower, higher thermal conductivity.2. Compared with austenitic stainless steel, the compressive strength of duplex stainless steel 2205 alloy is twice that of austenitic stainless steel. Compared with 316L and 317L, the designer can reduce its weight.

duplex 2205 flangesDuplex 2205 flanges are made from an austenitic-ferritic stainless steel, which was once designed to supply greater power and corrosion resistance than 300 sequence stainless steels. It helps customers to keep away from stress corrosion cracking that is normally viewed with 316 and 317.
