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.

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

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.

Stainless steel plate is detection and shaping have to be off-line processing.

Super Duplex Steel UNS S32760 Welded Pipes are multi-purpose and possess good weldability, used widely in the offshore and marine industry for their acid corrosion resistance.S32760 Super Duplex Stainless Steel Pipes are highly alloyed with different metals and have a greater mechanical strength.

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.

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 PlateDuplex 2205 Plate is a two-phase, ferritic, austenitic 22% chromium, 3% molybdenum, 5 to 6% nickel alloyed stainless steel.

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.

2205 Duplex Stainless Steel BarDuplex 2205 Stainless Steel is a nitrogen-enhanced duplex used in purposes requiring excessive electricity and magnificent corrosion resistance. It is designed to mix accelerated resistance to stress corrosion cracking, pitting and crevice corrosion.

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

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.
